15 Press the Input Power softkey and enter the power level of the 500 MHz source
as -27 dBm (actual input power at the counter must be -27 dBm ± 0.5 dB).
16 Press the Perform Cal Step softkey to enter the data into the counter and initiate
the microwave oscillator calibration.
– If the calibration step PASSES, after a few seconds the counter momentarily
displays “Calibration step succeeded.”
– The internal calibration constants are updated.
–The Cal Count on the screen will increment.
17 Repeat steps 14 to 16 using each of the calibration frequencies and power
levels in Table 2-2 (total of 36 steps). For each calibration step, set the source
frequency and power accordingly.
