FIG.3 REAR PANEL
AC INLET: AC power input connector
INT/EXT TIME BASE SELECTOR:
Selects the source of the time base. EXT.STD. IN
sets up BNC as a nominal 600 input impedance
path for an external 10 MHz time base signal. INT.
STD. OUT sets up BNC to monitor the internal time
base signal.
GROUND TERMINAL
FUSE HOLDER: Replace fuse by unscrewing
INT/EXT TIME BASE BNC:
Provides a connector through which the internal time
base signal can be monitored or through which an
external time base signal can be applied (see item
above). The external signal should have a voltage
range of 1.5 V~5 V rms.
RS-232C CONNECTOR: Connector for serial interfacing with a computer.
