1. Program the Calibrator Mainframe to the output as listed in Table 3-23.
2. Using the N to BNC cable, connect the CHAN 1 connector on the Calibrator
Mainframe to the PM 6680 at the channel indicated in Table 3-23. You will need the
BNC-N adapter for the connection to Channel C.
3. Set the filter on the PM 6680 as indicated in the table. Allow the PM 6680 reading to
stabilize, then record the PM 6680 reading for each frequency listed for the
Calibrator Mainframe.
4. Invert the PM 6680’s frequency reading to derive the period. For example, a reading
of 1.000006345 kHz has a period of:
1/1.000006345 kHz = 0.999993655 ms.
Record the period in the table and compare to the tolerance column.
