I have a audio system for testing headsets that have a cDAQ 9174 CompactDAQ chassis (4 slot USB) and 3 modules:
NI 9205 32-Ch ±200 mV to ±10 V, 16-Bit, 250 kS/s Analog Input
NI 9263 4-Channel, 100 kS/s, 16-bit, ±10 V, Analog Output Module
NI 9403 C Series 32-Ch, 5 V/TTL Bidirectional Digital I/O Module
Headset speaker is connected to NI 9263 and a reference microphone is connected to NI 9205
When I need to do one audio test I use simultaneous one channel for generation and one for measurement.
What is the maximum sampling rate that I can use for this measurement?
In case of USB headset, speaker audio is generated by USB PC and measurement is by reference Microphone to NI 9205
In this case, what is the maximum sampling rate I can use?
Thanks for any help
