What is the minimum Interchannel delay for Interval Scanning in DAQCard 6062E?

I am trying to determine if a DAQ Card 6062E can be used to sample 10 channels each at 250 KSamples/sec. The gain is the same on all the channels and the output impedance of all the signals are low.
Is it possible to do this using the Interval Scanning method? If yes, how do I determine the mimimum interchannel delay? Can the data for all the channels at this rate be streamed to disk without losing any data?
Also, I do not understand the multiple channel scanning rate specification of the DAQCard-AI-16E-4 (250kS/s multichannel sampling rate). Can you please clarify if this card can be used for my application?
Regards,
Geeth

Hello,
Please take a look at the following link:
http://sine.ni.com/apps/we/nioc.vp?lang=US&cid=4371
The maximum sampling rate for DAQCARD-6062e is 500KS/s. Since the channels are multiplexed, the maximum sampling rate that you can achieve when you are doing acquisition on N channels is (500/N) ksamples/s.
Regarding the DAQCard-AI-16E-4, yes you would assume that usually if you are doing acquisition on 1 channel, you can get maximum sampling rate of 250 kS/s. But actually for this particular card, if you are doing acquisition on only one channel, you can achieve 500kS/s. But if you are performing acquisition on multiple channels, you can achieve maximum 250/N kS/s.
For information on interchannel delay, I would recommend you to take a look at t
he support page I am linking.

What's the minimum Clock Speed Requirement for GB3?

What's the minimum Clock Speed Requirement for GB3 (assuming one wishes to create and play mult. audio tracks within this current iLife app)? Is it 733mhz?
Here's what i was able to find on
iLife ’06 requirements:
To install iLife, you need:
• A Macintosh computer with a PowerPC G4, G5, or Intel Core processor; 733 MHZ or faster required for iDVD
• 256 MB of RAM; 512 MB recommended
• Mac OS X version 10.3.9 or Mac OS X version 10.4.3 or later; Mac OS X version 10.4.4 recommended
• iTunes 6.0.2 and QuickTime 7.0.4 (included)
• A DVD drive for installation
• 10 GB of disk space to install iLife '06 applications

Thanks Christoph, TIA, and AppleGuy!
Christoph, what model are you using? You said you have even less Mhz, but your model looks like the same as mine.
TIA, I looked at the other thread (thanks for the link) any idea what other models are affected by the sound output problem?
I probably will back up first just to be safe, and won't try running them both at the same time. I was hoping though to have full functionality of the Podcasting features plus all the old music ones without slowing the machine down.

What is the minimum pulse width output for PCI7831R?

I have a problem to generate the signal output by using PCI7831R.
I have used Labview FPGA program and PCI7831R with my experiment.
When I tried to output a signal which has a pulse width less than 2msec, Its pulth width becomes double or triple longer than I set.
For example, if I set the pulse width 1msec, its output pulse width became 3msec...
But if I set the pulse width 2.5msec, its output pulse width is just 2.5msec.
Internal clock is 40MHz and theoretical rate is 53.5MHz. And the cycle time of main loop is less than 0.5msec.
(I believe those value are fine to generate the 1msec pulth width output.)
My questions are
-What is the minimum pulse width for PCI7831R?
-Do you have any idea to solve this problem?
I attached the picutre of my VI.
(because this picture is a little old, It has broken wires. But it is fine now.)
If conditions are all good, this VI will output the signal during "Injection Duration(micros)" micro-second.
Thanks,

I'm sorry I could figure out what was the problem.
And I also find the minimum output pulse width on the catalog (12.5nsec).
Thanks,
Kaoru

What is the minimum download speed required for iTunes Match streaming

I have been very interested by iTunes Match, and I have read much about it. The only thing that I have not been able to find is the minimum bandwidth required to stream music to an iPhone. Specifically, I would be looking to stream to an iPhone 5, as well as an iPhone 4. If there is an official minimum requirement, please let me know. If there is no apple specified speed, I would be interested in what you found to be he minimum speed necessary for smooth streaming.
Thanks,

iPhone 4 and 5 will both work well with a good 3G service and much better with 4G. Song file is actually downloaded to allow for all conditions of viable mobile signal.

What are the minimum system requirements for GB 4?

What are the minimum system requirements for GB 4? I did search this forum but wasn't able to find a direct answer.
I'm running version 3.0.4 successfully on a lowly G4 733 but I suspect this is as far as I can go.
I'm updating to iDvd'08 and was also wondering if I can safely update to GB4 or not (from GB 3.0.7) on a G4 733 mhz Digital Audio. Any help would be sincerely appreciated. My guess is that I cannot but I'd like to confirm prior to attempting any further updates in GB.

I try my best to play it safely; always. And you were right, everything worked on the ext. FW HD flawlessly ...... truly amazing software!
(I did happen to check the activity Monitor w/in Utilities and it showed GB4 using about 60-67% of the CPU on a G4 733 ..... I'm assuming this is normal).

Not sure if there's a correct order to opening these apps as there has been in former versions of iLife ..... however, this (as shown above) is the order in which I opened all apps, and all worked well.

What are the minimum db user privileges required for CDC?

What are the minimum privileges required for the source data server user in order to to successfully implement CDC
Currently I'm getting an "Insufficient privileges" error when trying to start a CDC journal on a model. The error is happening on the step that creates a trigger on the table in the source schema.
Here's the situation:
The data server uses the user "ODI_TEMP" for its connection. ODI_TEMP has been granted select privileges on the desired tables in the source schema. When starting the CDC journal on the model for the source schema, ODI tries to create a trigger on the source tables. This fails since the ODI_TEMP user can't create triggers on anything outside of it's own schema. For obvious fundamental security reasons, we cannot give the ODI_TEMP user the CREATE ANY TRIGGER system privilege on the data source.
Journalizing is set up using JKM Oracle Consistent. ODI is 11g, DB is 11g.

Hi,
You can go for this
Grant CREATE ANY TRIGGER system privilege to ODI_TMP
Start the Journal , it will create triggers in ODI_TMP schema for the tables present in your source schema.
Now revoke CREATE ANY TRIGGER system privilege from ODI_TMP.
It will continue to work .. only when you are restarting the journal (due to adding or removing some tables in CDC) , you will be requiring CREATE ANY TRIGGER privilege.
Thanks,
Sutirtha

What are the minimum CPU and Memory requirements for R12 Vision instance?

We are in the process of trying to figure out what the minimum hardware requirements are for installing the R12 Vision instance. This Vision instance would only have 5 or less concurrent users. We may have to order a new server and we are wondering what the minimum CPU and memory would be? Oracle Support will not give us this information.
We aleady know how much disk space it will need.

How do I know what is the minimum resource requirement for OLAP 11g?

How do I know for OLAP 11gR1 ...
1. what is the minimum number of CPUs and speed required
2. how much minimum physical memory, SGA, PGA etc. is required?
Regards, Anirban

Hello Anirban,
In summary, since the OLAP option is an option to Oracle Database 11g, Enterprise Edition the minimum requirements in order to run the database would be identical to those necessary to run a "Data Warehousing" type installation. That being said starting up a database is a far cry from actually performing well while accessing and building OLAP Cubes in your Database.
There are lots of things to consider. For example: the complexity of your model; data sparcity; level of aggregation; system load, SLAs, etc..
Lets look at true minimum requirements and then consider what it would take to achieve good performance in your environment
TRUE MINIMUM...
I performed a test in my environment (Oracle Database 11g Release 2 (11.2.0.2.0) on Oracle Enterprise Linux 5.5) using Analytic Workspace Manager 11.2.0.2.0A and found the following minimum settings to work against the OLAPTRAIN schema (You may find it here http://www.oracle.com/technetwork/database/options/olap/index.html). This is a very small schema which we use for demonstration purposes.
I discovered that the database started with a memory_target of only 160m (apparently this is the absolute minimum for my environment). I knew that if the database successfully started that I would be able to query the Cube but maintain it? Running queries against the OLAPTRAIN Sales Cube, despite being slow, worked as anticipated. Next, I performed a maintain operation on the Sales Cube where I had to abort the job because it ran into memory issues at 160m, however, when I increased it to only 180m it did a complete maintain in a reasonable timeframe, albeit slow considering the limited resources.
MINIMUM REQUIREMENTS TO ENSURE REASONABLE PERFORMANCE IN YOUR ENVIRONMENT
Most importantly ensure you have a good cube design
Run a sample set of your data in order to define what "reasonable performance" is for your environment. Create a small representative cube in order to test both build and query performance while collecting and analyzing database statistics through AWR and ADDM. For OLAP option specific queries please take a look at http://wiki.oracle.com/page/OLAP+option+-DBASample+Scripts.
You could creat a view on top of your fact table and use the view to generate your OLAP Cube. This will allow you to test a more manageable amount of data. For example, if you have 10 years of data and want to determine the footprint and resources required in order to manage a Cube of this volume then consider scoping it down to a few months first then increase it by a measured amount in order to predict requirements. Monitor your resources and ensure you balance I/O, memory and processors. Since the OLAP option is a Enterprise Edition option it falls under Data Warehousing. As such there is plenty of literature available on oracle.com in order to define what it takes to achieve a balanced Data Warehouse.
I would recommend contacting Oracle Consulting or an Oracle Partner to determine the best fit for your environment.

[SOLVED] What is the minimum .reg configuration for monting eMMC2??

Hello Friends,
Greetings for the day!!
As, I have a board that contains the eMMC2(slot=3). We have made some changes in the driver for make it capable for slot=3. Now, the turn of .reg files. We have made all the required entries for Driver\BuiltIn\SDHC3. And driver is taking the values correctly.
Now the part of remaining entries related to file system, profiles, partition, partition table etc
I have made entries are as -

I have read lot of document related to the issue that eMMC2 is not mounted for most of the persons. In every document I have observed that they are using different keys and keys values.. I am confused that what is the minimum keys and keys values required
for the eMMC2 to be mounted apart from driver level.... ???

Anyone can tell me that what is the minimum .reg entries that is required to mount the eMMC2 ????

Hello Friends,
I am happy to intimate you that I have self solved the above problem with minimal configuration as shown below -

What's the minimum setting for WL as a proxy server

What's the minimum setting of weblogic.properties for WL as a proxy server?

Hi Michael,
Recommended setting is the default setting which is 25 .dot.
If your situation is abnormal and you see message delivery throttling state to “4” when the following performance counters are high or if you expect any of you integration
process could have impact on following counters, then you can consider the suggestion by Microsoft. Don’t change the default setting.
High process memory
Process memory usage (MB)
Process memory usage threshold (MB)
You can see these counters under “BizTalk:MessageAgent”
You can gauge these performance counter and its maximum values if have done any regression/performance testing in your test servers. If you have seen these counters having
high values and causing throttling, then you can update the Process memory usage.
Or unexpectedly you’re process high throughput messages in production which is causing these counters to go high and cause throttling, then up can update the Process memory
usage.
The above two cases where I know my expected process usage (by doing performance testing) or suddenly my production server processing has gone high due to unexpected business
hike (or any reasons) which caused throttling, then do changes to default throttling setting.
Just changing the default setting without actual reason could have adverse effect where you end up allocating
more processing capacities but the actual message processing message usage ever is low means you end up investing in underutilised resources.

HT4437 what are the minimum wireless requirements for airplay regards wireless strength ( DBs)

What are the minimum requierments for Apple Airplay? i need to know how strong in BDs the system con operate down to?

It is not a matter of single strength. That only tells you the amplitude of the radio connections which tells you nothing. What really matters is the speed of traffic across the connection and the number of dropped/lost packets. And single strength tells you neither of these. Interfearance, noise, collisions due to too many WiFi connections in the area impact the connection. You can have strong single strength and not be able to maintain a connection.
