Frequency Response Test Setup (60 MHz to 2.5 GHz, 2 to 22 GEIz)
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
