Setting Trigger Parameters for an External Trigger (Gate)
The external trigger (gate) signal is input from the TRIGGER INPUT connector
on the front panel. The maximum input voltage is ±10 V into a 1 MW input
impedance, and the maximum input voltage is 5 V
RMS
into a 50 W input
impedance.
Use the Slope or Polarity, and Level items in the side menu of the MODE menu
to set trigger (gate) parameters for an external trigger (gate) signal.
H Slope. This menu item sets the slope for the external trigger signal. Press the
Slope button in the side menu and select either Positive or Negative. When
Positive is selected, the output is triggered at the rising edge of the external
trigger signal; when Negative is selected, the output is triggered at the
falling edge of the external trigger signal.
H Polarity (Gated mode). This menu item sets the polarity for the gate that
outputs the waveform or sequence with an external gate signal. Press the
Polarity button in the side menu and select either Positive or Negative.
When Positive is selected, the waveform or sequence is output while the
level of the gate signal is higher than the gate level set with the side menu
Level item. When Negative is selected, the waveform or sequence is output
while the level of the gate signal is lower than the set gate level.
H Level. This item sets the trigger (gate) level for an external trigger (gate)
signal. Press the Level button in the side menu, then set the level with the
numeric keys or the general purpose knob. The trigger (gate) level can be set
in the range –5.0 V to 5.0 V in steps of 0.1 V.
