Burst Waveform(the sync delay is invalid)
1) When internal or munual trigger source is selected:
Infinite burst: the sync signal is the same as that of the basic
waveform.
N cycle burst: the sync signal is TTL high level at the start of the
burst and will change to TTL low level after the specified number of
cycles finished. For the sync signal, the frequency is the reciprocal
of the Burst Period and the duty cycle is
Carrier Period * Cycles / Burst Period.
Gated burst: the terminal is used to accept the external modulation
signal and there is no sync signal output.
2) When external trigger source is selected:
The terminal is used to accept the external trigger signal and there is no
sync signal output.
Output Set
1. Output Polarity
Set the output signal on the [CH1] connector as normal or inverted. Waveform
inversion is relative to the offset voltage. Press Utility Channel Set
Output Set Output to select “Normal” or “Invert”. The default is “Normal”.
The waveform is normally outputted in “Normal” mode and is inverted before
outputted in “Invert” mode. For example, the waveform of the first half period of
the cycle is positive in “Normal” mode and negative in “Invert” mode, as shown
in the figure below.
0 V
Offset
0 V
Normal Invert Normal Invert
Note: the sync signal related to the waveform is not inverted when the
waveform is inverted. To set the sync signal to invert, press Utility Channel
Set Sync Set Polarity and select “Invert”.
