STEP PROCEDURE 

LOC 

8.  Press the LOC Soft Key to display the LOC AMPL LEVEL Sequence Screen. 

9.  Connect Measuring Receiver Sensor Head to the ANT Connector. 

10.  Follow the on-screen prompts and recall stored calibration levels on the 

Measuring Receiver (para 2-2-3F[1] Step 2).  For the LOC AMPL LEVEL 
Sequence, the AM modulation setting error must be <0.5% and the amplitude 
setting error must be <0.1 dB. 

11.  Reference the following: 

z

  Step 1 of LOC AMPL LEVEL Sequence 

Turn modulation OFF to set and check RF level.  Toggling the UUT 
Modulation field between OFF and ON and the Measuring Receiver between 
AM and TUNED RF LEVEL several times may be required to meet the 
requirements of this step. 

z

  Step 2 of LOC AMPL LEVEL Sequence 

Once the VALUE: field has been set for minimum distortion, use the PREV 
Soft Key to return to Step 1.  Steps 1 and 2 are interactive; toggling between 
the two is required to meet the requirements of the steps. 

12.  When the LOC AMPL LEVEL Sequence is complete, press the SAVE & RETURN 

Soft Key to return to the AMPL LEVEL Cal Screen. 

MKR 

13.  Press the MKR Soft Key to display the MKR AMPL LEVEL Sequence Screen. 

14.  Connect 10 dB Attenuator between Measuring Receiver Sensor Head and ANT 

Connector. 

15.  Follow the on-screen prompts and recall stored calibration levels on the 

Measuring Receiver (para 2-2-3F[1] Step 2).  For the LOC AMPL LEVEL 
Sequence, the AM modulation setting error must be <1% and the amplitude 
setting error must be <0.1 dB (taking into account the 10 dB Attenuator). 

16.  Reference the following: 

z

  Step 1 to 2 of MKR AMPL LEVEL Sequence 

Turn modulation OFF to set and check RF level.  Toggling the UUT 
Modulation field between OFF and ON and the Measuring Receiver between 
AM and TUNED RF LEVEL several times may be required to meet the 
requirements of this step. 

z

  Step 3 of MKR AMPL LEVEL Sequence 

Select 15 kHz Low-Pass Filter on the Measuring Receiver. 

17.  When the MKR AMPL LEVEL Sequence is complete, press the SAVE & RETURN 

Soft Key to return to the AMPL LEVEL Cal Screen. 

18.  Press the RETURN Soft Key to return to the Calibration Screen.
