Keysight M9601A Startup Guide, Edition 2 23
Front Panel Features
Trigger and Interlock Terminals
The M9601A has the following terminals for the trigger signal input/output and
the interlock circuit status detection.
The M9601A has a 6-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 M9601A and ferrule
terminal cables such as Keysight PX0101A-001/002 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 module or
instrument. 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 must 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 M9601A output voltage is
limited to

42 V or less as you specified. If you set 0, the interlock function will be
same as inhibit control.
For more details, see “Installing Interlock Circuit” on page 29 .
CAUTION
Do not connect the interlock terminals to anything other than the interlock
circuit. Applying current or voltage to the terminals may damage the M9601A.
WARNING
Dangerous voltage, instrument maximum output voltage may appear at the High
force, High sense, and Guard terminals if the interlock terminals are closed or the
interlock circuit is closed.
Une tension dangereuse, une tension de sortie maximale de l'appareil peut
apparaître aux bornes High force, High sense et Guard si la borne Interlock est
fermée.
