4.9 Remote Inhibit Function
The remote inhibit input on the rear panel can be used to disable the output of the AC source.
This SMC input takes either a low level TTL signal or a contact closure. The mode of operation
can be programmed over the remote control interface using the OUTP:RI:MODE command. See
7004-961 programming manual for details.
The following modes are supported.
MODE OPERATION
LATCHING A TTL low at the RI input latches the output in the
protection shutdown state, which can only be cleared
by an OUTPut:PROTection:CLEar command or by
manually resetting the output.
LIVE The output state follows the state of the RI input. A TTL
low at the RI input turns the output off; a TTL high turns
the output on. This mode is equivalent to using the
Output On/Off button on the front panel.
Default mode. This mode is active at power up.
OFF The instrument ignores the RI input.
Table 4-4: Factory Default Power on Settings
The RI output state is saved as part of an instrument setup using the REGISTERS menu. It can
be made part of the power on setting if needed. The default state is LIVE.
