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.
