Unsure if my problem is a hardware or S/W problem or setting:
Configuration: Labview 7.0, MAX (unsure), SCXI 1100 (three modules), SCXI 1303, 6034E DAQ card.
The problem: 10 kHz hardware/SW filter: mulitple channels (~4) are posssible with huge standard deviation. For 4 Hz hardware/SW filter: multiple channels possible with excellent signal to noise, but there is interference in the chanels. For example: if I have three thermocouples, if I increase the temperature in one, all three increase at the same time.
Troubleshooting: It wasn't module depenant - changed between all three modules and the same trend occurs. Changed all MAX and DAQ assitant settings correctly. Reset PC to ensure valid test point.
By my calcuation: a 200 kS/sec card should produce at least 1000 samples per second if I used all the 96 Channels in the SCXI 1100 with Windows taking about half of the original card potential.
Appreciate any help,
