The connector accepts the ac input power cord.
The LINE SELECT switch selects line voltage of 115 or 230 volts. The selected voltage range is
visible on the switch.
The DC FUSE is a two ampere fast blow fuse. Provides main instrument protection.
The EXT DC INPUT power connector accepts the two-conductor input power cable. Input
voltage range is from 9 volts to
1s
volts de and 1.0 ampere maximum.
The input/output interface connector provides optional remote control capabilities with
either HP-IL (Option 003) or HP-IB. HP-IB is shown.
The 10 MHz IN/OUT BNC connector provides a 10 MHz calibration signal when the
INT EXT switch is in the INT position. With the switch in the EXT position, the IN/OUT
BNC connector becomes the external reference input for the counter .
The switch selects the internal 10 MHz oscillator or an external reference oscillator.
The interface capability label lists the standard interface functions of the counter for the
HP-IB or HP-Il.
The internal time base oscillator is adjusted through this opening.
The address switch is used to manually set the remote control address of the counter. The
five rightmost switch positions determine the address.
