In the remote position electrical gate signals con trol the counting gate. Two bridged LEMO connectors on Front panel. Less than l0nsec. Front panel push button for reset of,counter overflow, display and preset level outputs. Two bridged LEMO connectors on front panel.
Bridged inputs allow daisy chaining of gate signals from scaler to scaler.
Three least significant digits are blanked when prescaler is disabled. Turns off when counter is reset. A carry pulse will not be generated at reset. A five digit thumbwheel is used to set the preset number. At preset coincidence a -900mv minimum signal into 50 ohm signal is generated at the B Lemo connector.
