Part 1: LPF, Attenuator and A dapter Insertion Loss Characterization

1.Zero and calibrate the measuring receiver and 100 kHz to 1800 MHz power sensor in LOG mode as described in the measuring receiver operation manual.

CAUTION	Do not attempt to calibrate the low-power power sensor without
	the reference attenuator or damage to the low-power power
	sensor will occur.

2.Zero and calibrate the power meter and low-power power sensor, as described in the power meter operation manual.

3.Press INSTRUMENT PRESET on the synthesized sweeper, then set the controls as follows:
