6-56. Tunnel Diode Pulser Drive Amplitude Verification

This procedure uses the following equipment:
Hewlett-Packard 3458A Digital Multimeter
BNC(f) to Double Banana adapter
BNC cable supplied with the SC600
Set the Calibrator Mainframe in Scope Cal mode, Edge. Proceed with the following
steps:
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. Refer to Figure 6-2 for the
proper setup connections.
2. Activate the TD Pulser output by pushing the TDPULSE blue softkey. The output
should now be at 80 V peak-to-peak, 100 kHz, STANDBY.
3. Set the HP 3458A to DCV, NPLC = .001, LEVEL 1, TRIG LEVEL, and the DELAY
to .00012 for measuring the topline and DELAY to .00007 for measuring the
baseline. Manually range lock the HP 3458A to the 100 V dc range.
4. Change the Calibrator Mainframe output frequency to 10 kHz. Push the operate key,
and use the HP 3458A to measure the topline and baseline.
5. The peak-to-peak value is the difference between the topline and baseline. Record
these values in Table 6-28, and compare against the listed tolerance.
