20 If any calibration step FAILS, after several seconds the counter displays
“Calibration step failed” .
21 If the calibration fails (“ Calibration step failed ”), first verify the input frequency
and power are correct and the source output is connected and turned on.
Then, refer to “Troubleshooting the Counter” on page 160.
22 To check for error messages, refer to the Summary of Option 115 remote
microwave calibration: below for information on how to read the error
message(s) from a remote computer.
Table 2-3 Option 115 calibration frequencies and power levels
Test point Frequency (MHz) Power level 1 Power level 2 Power level 3
1 300 MHz -21 dBm -4 dBm +10 dBm
2 1000 MHz -21 dBm -4 dBm +10 dBm
3 3000 MHz -21 dBm -4 dBm +10 dBm
4 5000 MHz -21 dBm -4 dBm +10 dBm
5 7000 MHz -21 dBm -4 dBm +10 dBm
6 9000 MHz -21 dBm -4 dBm +10 dBm
7 10000 MHz -21 dBm -4 dBm +10 dBm
8 11000 MHz -21 dBm -4 dBm +10 dBm
9 12000 MHz -21 dBm -4 dBm +10 dBm

12 15000 MHz -21 dBm -4 dBm +10 dBm
NOTE
If the calibration fails for any calibration point (including zero-cal), the current
calibration constants for that frequency and power level, and the Cal Count,
remain unchanged.
