SSB Transmitters
171
Measurement Procedure:
1. Connect the Transmitter as shown.
CAUTION: The RF present at the Test Set RF IN/OUT connector must not exceed 60W
continuous (or 100 Watts for 10 sec/minute) or permanent instrument damage
may result.
On the Test Set:
2. Press the PRESET key.
3. Press the TX key.
Using the knob:
4. Set AF Anl In to SSB Demod.
On the Radio:
5. Key the Transmitter and keep keyed until the remaining steps are complet-
ed.
On the Test Set using the knob and data entry keys:
6. Set AFGen1 Lvl until a measurable RF signal is displayed (typically >5-10
mV).
Test Set Options Required
Spectrum Analyzer/Tracking Generator (option 102)
Special Test Considerations
Cable and adapter mismatch must be considered when
measuring harmonics and spurious emissions of a trans-
mitter. If an external attenuator is used, special care must
be taken to ensure the attenuator is not causing any spuri-
ous or harmonic emission. Also, if spurious emissions are
located, verify that the transmitter is the source, and not
another object radiated emissions near the test site
