Settings file
A PC file (with a .tr2 extension) that contains all
the logic and timing settings for an experiment.
Skip triggers
A setting that allows a channel to trigger only after
the specified number of input pulses.
Statically delayed pulse
In this timing mode, a channel waits for an input
signal, waits a specified delay time then sends a
pulse to the channel output.
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
The minimum increment of time used by the
LC220. This can range from 5 ns to 1000 ns and
can be generated from an internal or external clock.
Timer
Counter/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
Toggles its output state upon every input pulse.
Trigger
An input signal that initiates a channel function.
Trig220
The control software for the LC220.
Trigger validation mode
Also known as “Noise Suppression” mode. This
timing mode eliminates false triggers due to noise
on the input signal by requiring the signal to remain
high (or low) for a specified duration.
Update firmware
This menu function allows you to upgrade your
LC220’s firmware to the latest version, available at
www.labsmith.com.
