• The
Square
channel mode (Fig.
) allows the creation of a square TTL pulse sequence. This includes all sequence
options as the
CW
mode, with the following additions.
1. The
Frequency
sets the frequency (in Hz), which is the number of pulses per second. The frequency can also
be changed to the
Period
. For example, a signal at 10 Hz (frequency) will output one pulse every 100 ms
(period), whereas a signal at 0.5 Hz (frequency) will output one pulse every 2 seconds (period).
2. The
Time ON
defines the length of a single pulse. This time can also be converted to a
Duty Cycle
, which
indicates the % of the period the pulse duration corresponds to.
3. The
Pulse(s) per sequence
set the number of pulses per sequence. If it is set to 0, the number of pulses will
be infinite.
4. The
Number of sequence(s)
sets the number of times that the sequence will be repeated.
5. The
Delay between sequences
sets the delay between each sequence.
• The
Input
mode (Fig
) receives a signal that is translated to 0 (
Off
) or 1 (
On
). The channel can then be used
as a trigger source for all the other channels of the console. No
Sequence Options
or
Sequence Previews
are
available for this mode.
