CAUTION
Do not exceed +10 dBm input to either amplifier input.
NOTE
Verify the proper cal factors are loaded for the power sensor
module being utilized.
a. Measuring receiver setup
(1) Connect sensor module to the power reference output. Perform sensor zero
and calibration.
(2) Configure measuring receiver to measure power.
