the external clock supply is automatically
switched on when clock signal is fed to
EXT CLOCK.
resulting generator output frequency
f= fp: fe: 2-33 - 109 (fc in MHz)
fp = programmed frequency
all generator functions can be remote
controlled
acceptor handshake

address adjustment via the keyboard
with key ADDRESS, stored in the
battery buffered ram; initial value = 20
not for all commands
basic frequency, carrier frequency

dBm-level
DC-level
amplitude modulation 'on'
amplitude modulation 'off'
the header MA requires a numerical
extension 'X' to select between internal
and external modulation.
