Predefines

A set of standard variables and operators that can be used in
logic assignments.

Program All Channels

A function which sends all logic and timing settings to the
Model 725.

Programmable Logic Controller A device which combines logic and timing processors for

precise control of physical experiments.

Recall

Re-loads a stored Settings File.

Reset

Returns all channels of the Model 725 to their waiting
condition. Retriggering Counters and delay settings are reset as
well.

Retrigger

A channel setting that allows the channel to be triggered more
than once, if subsequent trigger pulses are received.

Scaling

In the Dynamically Delayed Trigger timing mode, scaling
determines the ratio of the distance between the two input
sensors to the distance of the target.

Settings File

A PC file (with a .trg extension) that contains all the logic and
timing settings for an experiment. Up to 256 Settings Files can
be stored and recalled from the Model 725.

Skip Triggers

A setting that allows a channel to trigger only after the
specified number of input pulses.

Store

Load a Settings File into the memory of the Model 725. The
settings can be recalled later.

Sweep

In the Delayed Pulse After Trigger timing mode, this settings
facilitates time-delay scanning experiments in which the delay
of the pulse relative to the trigger must be incremented by a
specified value each time the channel is triggered.

Time Base Settings

These General Settings determine the timing resolution of the
Model 725. Higher resolution allows 10ns timing resolution,
while low resolution allows delays over 1300 seconds.

Timer

Timer mode determines the time delay between two separate
input signals and reports it back to the PC.

Timing Mode

The eight functions that each channel can perform.

Toggle Mode

This mode toggles its output state upon every input pulse.
