Output Couple Control
This function lets you connect multiple instruments together and synchronize the output on/off
sequence across all units. Each unit that will be sequenced must also be "coupled" to the other units.
1. Couple the output on each unit as described under Sequencing the Output.
2. Set the delay offset of each individual unit to match the longest delay offset of the group.
3. Connect and configure the digital connector pins of the sequenced units as shown below.
Only pins 4 through 7 can be configured as "coupled" pins. The designated pins will function as both an
input and an output, with a negative transition on one pin providing the sequence signal to the other
pins. The polarity of the pins is not programmable; it is set to NEGative.
In this example, pin 6 is configured as the output On control. Pin 7 is configured as the output Off
control. The ground or Common pins are connected together.
Front Panel Menu Reference SCPI Command
Select System\IO\DigPort\Pins.
Select pin 6, then Function, then On Couple.
Select Pins., select pin7, then Function, then Off Couple.
Repeat these steps for units #2 and #3
To set pin 6 of unit 1 as the ON control:
DIG:PIN6:FUNC ONC
To configure pin 7 of unit 1 as the OFF control:
DIG:PIN7:FUNC OFFC
Repeat commands for units 2 and 3.
Once configured and enabled, turning the output on or off on any coupled unit will cause all coupled
units to turn on or off according to their user-programmed delays.
