Pulse Trigger
The trigger mode defaults to “Auto”. The SSG5000A offers five pulse trigger types: “Auto”,
“Key”, “Bus”, “Ext Trig” and “Ext Gate”.
Click the drop-down box corresponding to the trigger mode to select the desired type.
⚫
Auto: The default trigger method. The signal source satisfies the trigger condition at
any time. At this time, the two settings “Trig Slope” and “Trig Polarity” are hidden.
⚫
Key: Each time the “Click to trigger” key is pressed, the signal source initiates a pulse
modulation. At this time, t
he two settings “Trig Slope” and “Trig Polarity” are hidden.
⚫
Bus: Send one SCPI command: “*TRG”, the signal source initiates a pulse
modulation. At this time, the two settings “Trig Slope” and “Trig Polarity” are hidden.
⚫
Ext Trig: The source receives the trigger signal from the
[TRIG IN/OUT]
connector on
the rear panel. Each time a TTL pulse signal of the specified polarity is received, the
source initiates a pulse modulation. At this point, the “Trig Delay” and “Trigger Slope”
setting will be displayed and
the “Trig Polarity” setting will be hidden.
⚫
Ext Gate: The source receives the trigger signal from the
[TRIG IN/OUT]
connector
on the rear panel. Each time a TTL pulse signal of the specified polarity is received,
the source initiates a pulse modulation wi
thin its active level. At this point, the “Trig
Polarity” setting will be displayed and the “Trig Slope” setting will be hidden.
Trigger Delay
The trigger delay indicates the delay from the receipt of the external trigger signal to the
start of the first pulse. This parameter can be set by touching screen keyboard or pressing
the front panel keypad.
Note:
This setting item will be hidden when the modulation source is “Ext” or the pulse
trigger is not “Ext Trig”.
