Step #
What to do
Check
1
Unpack your device and place it in front of you
as shown on the next page.
2
Connect a load (for example your laser diode)
to the output.
Make sure to use both anode
and cathode connectors in
parallel.
3
Connect the PLB-21 or the USB cable
A driver is required in order to use the
LDP-QCW with a PC. See chapter
“Controlling the LDP-QCW via USB”
for more information
4
Connect the input power supply; make sure
that polarity is correct. The supply voltage must
be at least 24 V and about 5 V above the
desired capacitor bank voltage.
Make sure that your power
supply does not have any
voltage overshoots when
switching on or off. Do not exceed the
maximum operating voltage of 48 V
5
Switch the power supply on
6
If a PLB-21 is used, its display may show a
message about downloading a new driver.
Confirm this with YES.
See chapter “Controlling the LDP-QCW
using a PLB-21” for more information
7
Set all required parameters using the PLB-21 or
USB interface
See chapter “Controlling the LDP-QCW
using a PLB-21” for more information
8
Apply +5V to the MasterEnable pin of the BOB
connector
See chapter “Interface specifications”
for more information
9
Apply +5V to the Enable pin of the BOB
connector. This will enable the output
See chapter “Interface specifications”
for more information
10
Monitor the current pulses using an
oscilloscope connected to the current monitor
output
See chapter “Interface specifications”
for more information
11
Verify that the PULSER_OK signal is +5V
See chapter “Interface specifications”
for more information
