Enabling External Gate Control
• EXTin Selects external input usage for controlling T
o
: dis-
abled, edge triggered or level gated.
*NOTE: When the gate disables the System Timer, the timer is reset. The
gate edge, to enable the timer, will restart the System Timer, which synchro-
nizes the T
o
pulse to the gate and minimizes jitter relative to the gate. The
trigger threshold applies to all uses, channel and system, of the trigger/gate
input.
Power On Configuration
Upon power-up the unit will load the last configuration stored or recalled. If the
Autostart mode is enabled, the unit will begin generating pulses after loading the
latest configuration.
Setting Auto Start Mode
• Auto Auto run startup function - allows unit to automatically
generate pulses after startup is complete.
Setting System Serial Port Baud Rate
• Baud Rate Selects the baud rate (within the SYSTEM menu) for
the RS232 interface.
*NOTE: The unit will not respond to computer commands unless the appropri-
ate BAUD rate or GPIB address is selected.
Setting Communication GPIB Address
• GPIB Address Selects the GPIB Address (within the SYSTEM menu).
Setting Communication Echo Mode
• Comm Echo Selects whether to echo characters back to the host
computer or not.
Setting Key Repeat Rate
• Key Rate Sets the rate at which the keys will repeat when held
down. This is most useful when using the Up/Down ar-
rows to change parameters.
*NOTE: The key repeat rate is fairly accurate (better than one millisecond)
and may be used to increase/decrease a parameter at a set rate.
