To select the trigger output function:
DIG:PIN1:FUNC TOUT
To select the pin polarity:
DIG:PIN1:POL POS
DIG:PIN1:POL NEG
Output relay
Digital Control pin 1 can be programmed to function as an output relay. All pins are referenced to the Signal
Common pin.
When the output of the power supply is turned off, it is implemented by setting the output to 0 volts and 0.02 amps.
This gives a zero-output voltage without actually disconnecting the output. To disconnect the output, an external
relay must be connected between the output and the load. A TTL signal of either low true or high true is provided to
control an external relay. This signal can only be controlled with the remote command OUTPut:RELay OFF | ON. The
TTL output is available on the Digital IO pin 1 for channel 1. When the OUTPut:RELay state is "ON" on channel 1, the
TTL output of pin 1 is high if the Polarity is positive and pin 1 is low if the Polarity is negative.
The levels are reversed when the OUTPut:RELay state is "OFF".
From the front panel:
1. Press Utilities > I/O Config > Digital IO to access the Digital I/O window.
2. Select the pin you wish to configure. For example, press Pin 1 to configure Pin 1.
3. Press Function and select Relay. Select and program the remaining pins in the same manner. Press Back to
return to previous page.
4. Configure the polarity for each of the pin. Press Polarity Pos to select Positive and Polarity Neg to select Neg-
ative. Select and program the remaining pins in the same manner.
From the remote interface:
To select the trigger output function:
DIG:PIN1:FUNC REL
To select the pin polarity:
DIG:PIN1:POL POS
DIG:PIN1:POL NEG
Output couple controls
This function lets you connect multiple Keysight E36731A together and synchronize the output on/off sequence
across units. Each instrument that will be synchronized must have at least one coupled output.
1. Configure the outputs on each instrument as described under
Sequence. Set the output coupling mode to ON.
