upl()
uplink(‘on’,1) Turns on the uplink TT control and sets the
response time (in seconds). This is a good setting for testing so
you can see what the TT mirror is doing. Setting the time to 0.01
is good for operations (e.g. 100Hz uplink correction).
upl(2, 1.5) Send a move command to the uplink TT mirror.
First argument is the channel (2 is X, 3 is Y), second argument is
the voltage (-5 to + 5). When things are working properly you should
see the pointing laser diagnostic spot move off axis then back to close
to center (there is hysteresis with the PZTs so it never goes exactly
back to the start position).
Positive voltages on channel 2 moves the pointing spot up and left
(-V to down and right) and on channel 2 moves it to the up and right
(-V to down and left).
When done testing, make sure to set uplink(‘on’, 0.01) for
regular operations.
