Trigger And Interlock Terminals - Keysight M9614A Startup Manual

Front Panel Features

Trigger and Interlock Terminals

The M9614A/M9615A has the following terminals for the trigger signal
input/output and the interlock circuit status detection.
The M9614A/M9615A has a 5-pin terminal block on the front panel. The pin
assignment of the terminal block is shown in Figure 1-1. You can connect these
terminals by using a connector-terminal block furnished with the
M9614A/M9615A and ferrule terminal cables such as Keysight PX0101A-001 or
PX0101A-002 BNC to ferrule terminal cable.
Trig 1 and Trig 2 External trigger 1 and 2 terminals
These terminals are used to make synchronization with other modules or
instruments. You can specify the direction (input/output), the polarity (positive/
negative), and the pulse width of the trigger signal. The output trigger is
push-pull, and the trigger level is 0 V to 3.3 V at high impedance. The input trigger
should be the TTL level.
Intlk Interlock terminals
These terminals are used to connect an interlock circuit which is installed in your
test fixture or shielding box. The interlock circuit can be created by using two
mechanical switches and wire as shown in Figure 1-5. If the interlock terminals are
opened or the interlock circuit is opened, the output voltage is limited to 42 V or
less as you specified.
The interlock circuit is not necessary for the M9614A/M9615A because the
maximum output voltage is 30 V, but can be used to limit the output voltage to
the specified value. If you set the limit to 0 V, the interlock function will be same as
inhibit control.
For more details, see "Installing Interlock Circuit" on page 29.
Do not connect the interlock terminals to anything other than the interlock
circuit. Applying current or voltage to the terminals may damage the
M9614A/M9615A.
