Figure 6-19. Equipment Setup for SC300 Square Wave Measurements.
For all measurements, the HP 3458A is in DCV, manual ranging, with level triggering
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; LEVEL 1; DELAY .0002; TRIG LEVEL”. 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. Refer to Figure 6-19
for the proper connections.
6-104. DC Voltage Calibration
This procedure uses the following equipment:
• Hewlett-Packard 3458A Digital Multimeter
• 50 Ω feedthrough termination (as required in the calibration procedure)
• Shorted Dual Banana Connector
• BNC(f) to Double Banana adapter
• BNC cable supplied with the SC300
Note
Full calibration of the Voltage Function requires both dc and ac
calibration.
Refer to Figure 6-19 for the proper setup connections.
Set the Calibrator Mainframe in Scope Cal mode, DC Voltage section. Follow these
steps to calibrate DC Voltage:
1. Connect the Calibrator Mainframe’s SCOPE connector to the HP 3458A input, using
the BNC cable and the BNC(f) to Double Banana adapter.
2. Set the HP 3458A to DCV, Auto Range, NPLC = 10, FIXEDZ = on.
3. Press the GO ON blue softkey.
