Agilent U2356A Configuration

[vt92]

Hello all,

I'm having trouble getting my Agilent U2356A configured correctly for my application.  My task is simple: measured 10 samples at 100 Hz on channel 101.  I want differential mode, unipolar (0-5V).  I have verifed my connections using the Agilent measurement tool, but when I try to acquire data with LabVIEW I don't get the correct voltage.

Here are the parameters that I am using:

ROUT:SCAN (@101)

ROUT:CHAN:POL UNIP, (@101)

ROUT:CHAN:RANG 5, (@101)

ROUT:CHAN:STYP DIFF, (@101)

ACQ:POIN 10

ACQ:SRAT 100

Any suggestions?

How does the voltage you are reading differ from the expected voltage?

I talked to an Agilent support person and we resolved the problem.  I was "unflattening" as U16 instead of I16, which threw off the conversion.
