input from the synchronization source and the signal
output to the main output.
The frequency of the input signal is displayed on the
screen.
Frequency range 20Hz to 10MHz
Synchronization target Only external trigger input terminal is available.
In addition, CH2 can select the same trigger source as
CH1.
Trigger delay setting is invalid.
Synchronization source input
Polarity Positive, Negative (switch)
Input connector External trigger input terminal (TRIG IN)
Input signal and input impedance depend on external
trigger input specification.
Phase difference The phase between the signal input from the
synchronization source and the signal output to the
main-output can be set freely in the phase setting
(however, it will not become the same phase with 0
setting).
Limitations
・
Not available for the FM, PSK, FSK, frequency sweep and burst except auto, and
when the waveform is noise, DC and pulse.
・
Not available together with the sequence function (→17.11)
・
Not available when in 2-
channel coordination operation (→17.13)
However, by making the same synchronization source of CH2 to CH1,
equivalent operation to the 2-phase output, differential output, differential
output 2 can be achieved.
17.10 Trigger
External trigger input Independent for each channel, however CH1 input can be
shared with CH2
Usage For single sweep, gated single sweep, trigger burst, gate,
trigger gate and synclator functions
Input voltage TTL level (low level 0.8V or lower, high level is 2.6V or
higher)
Maximum allowable input -0.5V to +5.5V
Polarity Switches positive, negative or off (off is not available for
synclator)
Each setting is independent for FSK/PSK, sweep and
synclator.
Minimum pulse width 5ns
