InstrumentStudio record memory and PXI-5105

[Mykeil]

Hi,

I use InstrumentStudio 20.3 with PXI-5105. The card has 16 MByte record memory, which gives 8 Mbyte Samples memory for all channels.

The card has 8 channels. When I disable 7 channels and leave one to sample, the record memory stays at 1 MSample and not increases to maximum value. It never switches to value above 1MSample.

Am I doing something wrong or the software is limited?

Thank you very much.

Best Regards,

Mykeil

Hi Mykeil, 

Under the horizontal settings for the Oscilliscope in InstrumentStudio, you'll find a setting for "Data display".  Changing that setting from "Live" to "On demand" should allow for larger record sizes (>1 MSample).  In addition to controlling the thumbnail preview, this setting also limits record size to maintain quick update rates. 

This setting's effect on the maximum record size is not well documented, and I've filed a bug report on InstrumentStudio for our upcoming release to better document this.
