Using the Self-Calibration Routines with Option 105
The spectrum analyzer self-calibration routines (initiated by pressing CAL AMPTD or
CAL FREQ & AMPTD ) should be performed prior to using the Option 105 functions. Use the
following procedure to perform the self-calibration routines and to check the results of the
self-calibration routines.
Note
Be sure that the GATE TRIGGER INPUT connector (on the spectrum analyzer
rear panel) is not connected to anything while performing the spectrum
analyzer self-calibration routines.
1. Remove the cable from the GATE TRIGGER INPUT connector.
2. Connect the CAL OUT connector to the spectrum analyzer input connector with the
calibration cable.
3. Press a. Press either CAL FREQ & AMPTD (to perform the frequency and amplitude
self-calibration routines) or CAL AMPTD (to perform the amplitude self-calibration routine).
4. When the self-calibration routines have successfully completed, press CAL STORE .
5. Press COAL), More 1 of 4 ,
More 2 of 4, Service Diag , DISPLAY CAL DATA, then
NEXT PAGE.
6. Verify that the number displayed for GATE, in the lower left corner, is between
0.98 and 1.0 (see Figure 4-30).
