T2
Channel 2 output -- designed specifically for use as a solid-state laser Q-switch trigger and
has all the capabilities of the other output channels, including several special modes which af-
fect only the output of Channel 2.
Ext/Gate
External Trigger or Gate signal input -- used as either an external signal to trigger the genera-
tion of pulses or as a gate signal to enable and disable the outputs.
Output Voltage Adjustment
The maximum output voltage of all output channels is adjusted by turning the potentiometer la-
beled VOUT. Turn clockwise to increase the voltage, counter-clockwise to decrease the volt-
age. The maximum voltage possible is 20 Volts into a high-impedance load or 10 Volts into a
50 Ohm load.
Serial Port
This is a 9-pin D-sub connector for the RS232 interface that comes standard with the
9412/9412A. It is pinned to be directly connected to a standard IBM-PC serial port -- use a
straight-through cable (not a null modem cable) to connect to a PC.
AC Input
A standard IEC instrument-type cord should be used. The 9412/9412A is supplied with a
power cord that fits the type of socket used in your country.
Before plugging in, please make sure that the voltage selection switch is set
to the proper setting for your country (either 110V or 220V).
Line Voltage Selection
This switch is used to select the voltage level used in your country -- make sure that it is on
the proper setting or the 9412/9412A could be damaged.
