generator output level as necessary for proper meter deflection.
3) After the previous step, the final signal generator levelshould be less –3dBu for 12
dB SINAD.
S-Meter Calibration
1) While tuned to 51.000 MHz,and turn the radio off. Press the [PWR] and [SACN] of
the panel and hold while you turn the radio on. The radio now is in the Alignment
Mode.
2) The [SCAN] buttons on the panel to select the “MAIN S-METER 1”,and press the
[ENT] button.
3) The RF signal generator turned to the same frequency, set the generator for
±
3.5
kHz deviation with 1kHz tone modulation,and set the output level for -5dBu at the
antenna jack, press the [ENT] button.
5) The [SCAN] buttons on the panel to select the “MAIN S-METER 5”,and press the
[ENT] button.
6) The RF signal generator turned to the same frequency, set the generator for
±
3.5
kHz deviation with 1kHz tone modulation,and set the output level for +28dBu at the
antenna jack, and press the [ENT] button.
