How to
Obtain �Correct� Front-Panel Display for
Agilent 33120A Function/Arbitrary Waveform Generator
The function/arbitrary
waveform generator assumes you are driving a 50-ohm load (this is the power-on
default behavior). If you are driving a high-impedance load (such as the clock
input of a digital gate, or an op-amp input) then you will see that the actual
voltage waveform is two times higher than the displayed value. Follow these
instructions to produce a correct display for high-impedance loads:
