For all measurements, the HP 3458A is in DCV, manual ranging, with external trigger
enabled. A convenient method to make these measurements from the HP 3458A's front
panel is to program these settings into several of the user defined keys on its front panel.
For example, to make topline measurements at 1 kHz, you would set the DMM to "NPLC
.01; DELAY .0007; TRIG EXT". To find the average of multiple readings, you can
program one of the keys to "MATH OFF; MATH STAT" and then use the "RMATH
MEAN" function to recall the average or mean value.
For this application, if making measurements of a signal > 1 kHz, the HP
3458A has been known to have .05% to .1% peaking in the 100 mV range.
For these signals, lock the HP 3458A to the 1 V range.
