3.3.1.6 Checking the IF PCB signals
The following table provides reference information for checking
signals on the IF PCB:
Signal name Signal function
COR Voltage to operate the laser power supply 0 to 5V
GPC Specification of pressure inside discharge tube 0 to 15V
MOUT
Sampling output of monitored laser power supply currents
and voltages.
Data is output in the order: pressure, voltage (No. 1);
pressure, current (No. 1); pressure, voltage (No. 2); and so
on.
LPW Monitoring of laser output power 0 to 10V
LTP
Monitoring of pressure inside discharge tube 0 to 9V
1V/1.33kPa (PRG×1)
Monitored values are clamped to 9V.
PAN1
Sampling outputs of monitored laser outputs and pressure
values inside discharge tube are output alternately.
