To Use the Channel Gating Function

Each channel may use the external input to gate or control its output. The gate

controls the triggering of the channel. Once a channel has started to produce a

pulse it will complete the pulse, even if the gate has been removed. No partial

pulses will be produced. To use the gate, set the following parameters

- Within the Gate/Trig menu

Level: Set the threshold voltage for the external input.

- Within the Channel menu

Gate: Select active high or active low.

External Input Overview

The external input may be used to trigger the unit or to gate the system or channel

timers. When used as a trigger input, the external input acts as a system start

pulse. Depending on the system mode, the result of a trigger input can be either

a single pulse, a burst of pulses or the start of a stream of pulses.

To Generate a Pulse on Every Trigger Input

To generate a pulse on every external trigger received, set the following

parameters:

- Within the Mode menu:

Mode: Select the Single Shot mode.

- Within the Gate/Trig menu:

EXTin: Select Triggered mode.

Level: Set the trigger threshold level.

Edge: Select which edge, rising or falling, to trigger on.

Pressing the RUN/STOP key will arm the unit. Once the unit is armed, it will

generate a T

pulse for every external trigger received. Pressing the

RUN/STOP key will disarm the unit. This mode corresponds to the normal

external trigger mode found on most other pulse generators.

To Generate a Burst of Pulses on Every Trigger Input

To generate a burst of pulses for every external trigger received set the following

parameters:

-Within the Mode menu

Mode: Select the Burst mode.

Burst: Set the number of pulses to generate in each burst.
