Operating Basics
4.
Modulation mode:
When internal
modulation source is
selected, the trigger
output is a square
waveform of the
same frequency as
the modulating signal.
When an external
modulation source is
selected, the trigger
output is disabled.
5.
Burst Mode: When
internal trigger source
is selected, the trigger
output is a square
waveform and the
rising edge at the
start of each burst
period.
When an external
trigger source is
selected, the trigger
output is high during
the time the trigger
input is high.
When a setting frequency of an output waveform is higher than 4.9 MHz, a
divided frequency that is lower than 4.9 MHz is output from the Trigger Out. See
the table below:
Set frequency of output waveform (MHz)
Trigger output frequency (MHz)
〜
4.900 000 000 00
Fs
4.900 000 000 01 to 14.700 000 000 0
Fs/3
14.700 000 000 1 to 20.000 000 000 0
Fs/5
NOTE.
When the instrument outputs a modulation waveform, the Trigger Output
signal cannot be output if you select External as the modulation source.
