•
BNC cable supplied with the SC600
Refer to Figure 6-6 for proper setup connections. Set the Calibrator Mainframe to
SCOPE mode, with the Edge menu on the display. Press
O
on the Calibrator
Mainframe to activate the output. Then follow these steps to verify Edge frequency.
1.
Set the PM 6680’s FUNCTION to measure frequency on channel A with auto
trigger, measurement time set to 1 second or longer, 50
Ω
impedance, and filter off.
2.
Using the BNC cable, connect the SCOPE connector on the Calibrator Mainframe to
PM 6680 channel A.
3.
Program the Calibrator Mainframe to output 2.5 V at each frequency listed in Table
6-25.
4.
Allow the PM 6680 reading to stabilize, then record the PM 6680 reading for each
frequency listed in Table 6-25. Compare to the tolerance column of Table 6-25.

6-53. Edge Duty Cycle Verification
This procedure uses the following equipment:
•
PM 6680 Frequency Counter
•
BNC cable supplied with the SC600
Refer to Figure 6-6 for proper setup connections. Set the Calibrator Mainframe to
SCOPE mode, with the Edge menu on the display. Press
O
on the Calibrator
Mainframe to activate the output. Then follow these steps to verify Edge duty cycle.
1.
Set the PM 6680’s FUNCTION to measure duty cycle on channel A with auto
trigger, measurement time set to 1 second or longer, 50
Ω
impedance, and filter off.
2.
Using the BNC cable, connect the SCOPE connector on the Calibrator Mainframe to
PM 6680 channel A.
3.
Program the Calibrator Mainframe to output 2.5 V at 1 MHz.
4.
Allow the PM 6680 reading to stabilize. Compare the duty cycle reading to 50%
±
5%.
6-54. Edge Rise Time Verification
This procedure tests the edge function’s rise time. Aberrations are also checked with the
Tektronix 11801 oscilloscope and SD-22/26 sampling head.
The following equipment is used to verify the edge rise time.
