1. When making measurements at 1 kHz, set the HP 3458A to DCV, NPLC = .01,
TRIG EXT, and the DELAY to .0007 for measuring the topline of the wave form,
and the DELAY to .0012 for measuring the baseline of the wave form. Manually
lock the HP 3458A to the range that gives the most resolution for the topline
measurements. Use this same range for the corresponding baseline measurements at
each step.
2. Enable the Calibrator Mainframe external trigger by toggling the blue softkey under
TRIG to /1.
3. Measure the topline first, as indicated in Table 6-21. For each measurement, take
samples for at least two seconds, using the HP 3458A MATH functions to determine
the average or mean value. See “Setup for SC600 Voltage Square Wave
Measurements” for more details.
4. Measure the baseline of each output after the corresponding topline measurement, as
indicated in Table 6-21. The peak-to-peak value is the difference between the topline
and baseline measurements. Compare the result to the tolerance column.
5. When making measurements at the other frequencies, set up the HP 3458A (NPLC
and topline and baseline DELAY) per Table 6-16. (See “Setup for SC600 Voltage
Square Wave Measurements.”)
