Hello,
I am trying to change the mode of measurement on our 4294A impedance analyzer from taking a measurement of impedance vs frequency (from 40Hz to 10MHz), at 5mVac constant bias, to taking a measurement at one frequency over time. I would like to monitor the change in impedance vs time, at say 100kHz and 100mVac.
I tried to put the analyzer into "zero span sweep" mode to take data at a constant frequency and AC bias (as per page 94 of the user's manual), but wasn't able to actually start the measurement - on the oscilloscope the 4294A was still scanning the previously setup frequency window.
Anybody familiar with this mode of use? And how to switch to constant frequency mode?
Thanks!
James
Hello,
How about changing the sweep parameter to [OLEV] (= Oscillator level) for your purpse? Please check page 84 of Operation manual (Seventh Edition)
