36. Connect equipment as shown in Figure 2-19, with one resistive
output of the power splitter connected to the power meter/power
sensor, and the second resistive output connected to the spectrum
analyzer RF INPUT using an APC 3.5 (m) to Type N (m) adapter.
Connect the power meter rear panel RECORDER OUTPUT to the
synthesized sweeper front panel LEVELING EXT INPUT.
37. On the power meter, verify that the [RANGE HOLD) switch is off.
Consult the power sensor Cal Factor versus Frequency graph or
table and set the power meter CAL FACTOR

switch to the 100
MHz calibration setting.

40. On the power meter, press (RANGE HOLD) (turning it on).
41. On the synthesized sweeper, press [POWER LEVEL) and adjust the
ENTRY knob for a power meter indication of -10.00 ho.03

Note
Do not vary the synthesized sweeper POWER LEVEL setting (internal
leveling) or METER REF and METER ATN settings (external power
meter leveling) for the remaining steps in this test procedure.
