• Notes
• The Advance B4B is a AM/CW RF signal generator, which covers frequencies from 30 kHz to 30 MHz in six bands. Accuracy within ± 1 % is given. The modulation can be internal (400 Hz) or external (10 Hz to 10 kHz). A meter on the front panel monitors either the modulation or the RF amplitude.
