SYNC 2 Output
The SYNC2 output generates a single TTL pulse for synchronizing other
instruments to the output waveform. The SYNC2 signal always appears
at a fixed point relative to the waveform. The location of the signal along
the waveform is programmable.
SYNC 3 Output
The SYNC3 output generates a single TTL pulse for synchronizing other
instruments to the output waveform. The SYNC3 signal always appears
at a fixed point relative to the waveform. The location of the signal along
the waveform is programmable.
Trigger 1 Input
In general, the trigger inputs accept signals that stimulate the output
waveforms. The trigger input is inactive when channel 1 is in continuous
operating mode. When placed in trigger, gated or burst mode, the
trigger input is made active and waits for the right condition to trigger the
instrument. In
trigger and burst
modes, the trigger input is
edge
sensitive
, i.e., it senses transitions from high to low or from low to high
to trigger the Model 3153. The direction of the transition is
programmable. In
gated mode
, the trigger input is
level sensitive
, i.e., the
Model 3153 is gated when the logic level is high and idle when the level
is logic low. Trigger level for this input is programmable.
In master-slave mode, the trigger 1 input is also used as the master
trigger for the whole generator. When other channels are coupled to
channel 1, all other trigger inputs are disabled.
Trigger 2 Input
The trigger 2 input is inactive when channel 2 is in continuous operating
mode. When placed in trigger, gated or burst mode, the trigger input is
made active and waits for the right condition to trigger the instrument. In
trigger and burst
modes, the trigger input is
edge sensitive
, i.e., it
senses transitions from high to low or from low to high to trigger the
Model 3153. The direction of the transition is programmable. In
gated
mode
, the trigger input is
level sensitive
, i.e., the Model 3153 is gated
when the logic level is high and idle when the level is logic low. Trigger
2 input accepts TTL level signals only.
If channel 2 is coupled to channel 1, this input is disabled and channel
1 triggers override the state of this input.
Trigger 3 Input
The trigger 3 input is inactive when channel 3 is in continuous operating
mode. When placed in trigger, gated or burst mode, the trigger input is
made active and waits for the right condition to trigger the instrument. In
trigger and burst
modes, the trigger input is
edge sensitive
, i.e., it
senses transitions from high to low or from low to high to trigger the
Model 3153. The direction of the transition is programmable. In
gated
mode
, the trigger input is
level sensitive
, i.e., the Model 3153 is gated
when the logic level is high and idle when the level is logic low. Trigger
3 input accepts TTL level signals only.
