How to get started
Step
What to do
Check
1
Unpack your device.
2
Make a short at the output.
3
Turn the high voltage to the lowest value
(turn poti fully counterclockwise).
4
Connect a pulse source with the desired
pulse width to the selected triggering
input.
E.g. 100 ns, 100 Hz reprate.
5
Connect your scope.
Select 50 Ohm termination, trig on
neg. falling edge, 200 mV/div.
6
Apply the supply voltage.
Security advice: Do not touch any leads
of the output or the output capacitors as
they are connected to a high voltage of up
to 100 V.
Connect a 15 .. 24 V DC power
supply to the pin header. See page
5 for details.
Note: Some supplies have a
voltage overshoot during turn
on/turn off. This may damage the
device.
7
Adjust the value of the desired pulse
current (turn the poti clockwise until the
current reaches the desired level).
8
Disconnect the supply, remove the short at
the output and assemble the laser diode
(polarity!).
9
Reconnect the supply and check the
optical output of your laser diode.
Note: The actual current is always
some percent lower than the value
of step 7. Adjust the current with
help of the poti.
Do not use PLCS-21 with a higher supply voltage than 15 V. If you use the PLCS-21 with
higher voltage than 15 V the device will be damaged.
