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
0
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.
