Log Fidelity
5. Set the power sensor cal factor for 810 MHz on the measuring
receiver.
6. On the synthesized sweeper, press POWER LEVEL and adjust the
output amplitude so that the analyzer marker amplitude reads
−9 dBm ±0.05 dB.
7. Record the measuring receiver power reading in Table 2-17.
8. Adjust the output amplitude of the sweeper for analyzer marker
amplitude readings of −14 dBm and −19 dBm.
9. Record the measuring receiver power readings in Table 2-17. The
readings should be within the limits shown.
