o Burst Counts: Selects the number of pulses to output with each input clock
pulse. Valid input is 1-1,000,000.
o Single Shot: Will produce one pulse each time the channel is armed.

Sync Source: Selects the timing reference for the selected channel. Each channel may
be set to sync to T
0
or may be set to sync to a different channel. It should be noted that
if a channel is set to sync to a separate channel a negative delay may be used as long
as that delay does not require the pulse be produced before the T
0
pulse is produced.
For example: the value of (T
0
+ Sync source delay + channel delay) must be greater
than or equal to 0.

Wait Counts: Selects how many T
0
pulses to wait until the channel outputs its first
pulse. Valid input is 0-1,000,000.

Polarity: Selects the Channel’s Polarity. Normal is active HIGH, Inverted is active
LOW. The polarity function is not available on the virtual channels.

Mux: The outputs of each of the Channel Timers are routed to a set of multiplexers.
This allows routing of any or all Channel Timers to any or all of the units’ outputs. In the
normal mode of operation, the output of the n
th
Channel Timer is routed to the n
th
output
connector. As an example, if a double pulse is required on Channel A, one can multiplex
the Channel A timer with the Channel B timer, then adjust each timer to provide the
necessary pulses.
Only the timing parameters are multiplexed together, not the actual
output amplitudes.

Gate Mode: Selection determines which active state will gate the selected channel
output.
