I notice on the 34461A datasheet it claims a reading rate of 1000 rdgs/s. I need to sample a voltage at this sample rate. When looking at the manual it seems that only the 34465A and 34470A can sample at anything like this. I have tried logging in stand alone and via the PC but can only get a sample rate of around 2 Hz. Is it possible to obtain samples at 1000 Hz with this unit or do I need the 34465A? If it is possible can you give me a step by step process?
Kind Regards
Tom
Hi Tom, to reach 1000/s you must turn off some feature and adjust PLC.
I have tested with my 34410A with these commands : results was 1000 samples/sec.
Now with your 34461A, based on data sheet, you can reach 1000 samples/sec with PLC=0.02. It is the maximum speed with the 34461A.

CONF:VOLT:DC 10 (in this example, range set at 10V)
VOLT:DC:NPLC 0.06 (setting of PLC to reach 1000sample/sec, use PLC = 0.02 for 34461a)
SAMP:COUN 1
TRIG: COUN 1000 (1000 sample before read data by FETCH command)
TRIG:DEL 0 (delay set to minimum)
SENS:ZERO:AUTO OFF (disable auto zero feature)
TRIG:SOUR IMM
:INIT (start reading of 1000 samples)
:FETCH? (read data)
