4.4 CALIBRATION OF THE TEST PROBE

For some test probe measurements it is necessary to use a test probe calibrated with a specified multi
meter.
NECESSARY EQUIPMENT FOR THIS PROCEDURE:
1. Diagram for the measurements
2. Test probe
3. Multi meter
4. New factory adjusted RT2047

4.5 PROCEDURE FOR CALIBRATION

1. Switch on the set.
2. Select channel 28.
3. Remove coax cable from the soldering point for F
it with a 50 resistor.
4. Connect the test probe to the point mentioned above and record the result in the diagram.
5. Remove the resistor and solder back the coax cable.
6. Follow the procedure mentioned above by measuring the levels from F
Synthesizer and the TX drive level from the TX-Exciter.
All other test probe measurements are relative and ought to be measured with the same test probe and
recorded in the diagram.
