The charge level indicator illuminates when the capacitor bank is fully charged. The
current monitor is an oscilloscope compatible reference voltage to monitor the
current pulse, 1A = 100mV.
External Trigger
Trig In (BNC) -- external signal input to trigger the generation of pulses.
Optoisolated input, 3-15V (>3mA). Pressing the RUN button in the external trigger
mode arms the system and waits for an external trigger input.
Sync Out
This is a BNC connector which provides a TTL sync output when the instrument is
fired. This signal is generated by the internal clock and therefore the actual pulse
output will be delayed relative to the Sync Out as specified by the channel delay
parameter.
Interlock
A switch is provided to arm/disarm the system. This switch is used with the interlock
input on the rear panel to control pulse generation of the system. A READY
indicator is provided to indicate that the rear interlock is satisfied and the arm/disarm
switch is in the armed position. No pulses will be generated unless the LED is on.
When the system is disarmed, a relay disconnects the bank voltage from the output
jacks.
Rear Panel
Interlock
This is a BNC connector which must be appropriately connected to allow the
instrument to generate pulses. The input must be shorted to satisfy the interlock.
Serial Port
This is a 9-pin D-sub connector for the RS232 interface that comes standard with the
9700. 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.
