AMPLITUDE MODULATION
The following specifications apply to the
Channel A and Channel B outputs with
external modulation or to the Channel A
output with Internal modulation (Channel B
is the modulation source) External ampli-
tude modulation is allowed in any mode
while internal amplitude modulation is
allowed only ~n the Two-Channel mode
WAVEFORMS: Sine, square or pulse
(pulse allowed in external only)
CARRIER FREQUENCY RANGE: DC to
13 MHz
MODULATION FREQUENCY RANGE:
DC to 100 kHz
MODULATION DEPTH: 0 to 100%
The following specifications apply at
10 MHz carrier frequency 1 kHz modula
