Basic Operation
Modulating the Carrier Signal
3. Enable modulation of the RF output: Press the Mod On/Off key until the LED lights.
If you enable modulation without an active modulation format, the carrier signal does not
modulate until you subsequently turn on a modulation format.
NOTE To turn modulation off, press the Mod On/Off key until the LED turns off.
When the Mod On/Off key is off, the carrier signal is not modulated, even with an active
modulation format.
4. To make the modulated carrier available at the RF output connector, press the RF On/Off key until
the LED lights.
