TYPICAL TEST PROCEDURES
Tone (sine wave symbol)
Tone AGC was designed for continuous tones. Once the AGC has set the gain the AGC circuit
will verify the output level and correct if necessary, approximately every two seconds.
1. Connect an audio generator such as the Ramsey SG560 to the MOD IN jack. Set the
audio generator's level to approximately 1 Vpp. (50 mVpp to 5 Vpp acceptable).
2. Set the generator for desired RF frequency. Example: 464.15 MHz, Press
3. Turn on external deviation by pressing
4. Select the tone AGC mode by pressing
5. Set the desired modulation type by pressing
6. Set the required FM deviation or AM percent of modulation. Examples: for FM 3 kHz

deviation, press
Do not reproduce or distribute.
For 50% AM, press
7. The AGC display (lower center of GENERATE screen) should show "Good". If it shows
"Low" increase the audio input level. If it displays "Adj" it is internally adjusting the au-
dio level to give the proper output modulation.
8. The COM3010 is now transmitting the tone at the requested frequency and modula-
tion.
