Hello,

The 34401A is not longer available in Canada. We need to change and use the 34461A as a replacement and we are having trouble with the peak-to-peak measurements (We are using LabVIEW).

We use the peak-to-peak option while reading a communication line in order to get the min and max values. The code:

34410A
CONF:VOLT:AC
VOLT:AC:PEAK:STAT ON
INIT
FETC?

FETC:VOLT:AC:PTP?

This code no longer works with the 34461A. Reading the AC will only give the RMS values. We dont really care how to get the min-max of the communication channel, as long as it is in a respectable time (10s at most...). Reading the signal with DC pretty much stays around the 0V. The communication signal is ±100mv. We verify the min-max range to be around 200mV.

Thanks
