N67xx DUT Power Supply Installation

Inhibit Input

Pin 3 can be configured as a remote inhibit input. The polarity of pin 3 can also be

configured. Pin 8 is the common for pin 3.

The Inhibit Input function lets an external input signal control the output state of all

the output channels in the DUT power supply. The signal latency is 5 microseconds.

Pin 3 can be programmed for the following Inhibit modes, which are stored in

non-volatile memory:

Description

LATChing

Causes a logic-true transition on the Inhibit input to disable all outputs. The

outputs will remain disabled after the inhibit signal is received.

LIVE

Allows the enabled outputs to follow the state of the Inhibit input. When the

Inhibit input is true, the outputs are disabled. When the Inhibit input is false, the

outputs are re-enabled.

OFF

The Inhibit input is ignored.
