2-5. INSTALLATION INTO SYSTEM
The -hp- 3047A is supplied with the -hp- 35601A Spectrum Analyzer Interface already in­
stalled. Unless the instrument has been removed from the system for calibration or service,
just check for proper fuse installation and line voltage selection before applying power to the
instrument.
2-6. Line Voltage and Fuse Selection
fCAUTIONj
Before applying ac-line power to the -hp- 35601 A, be sure that
the VOLTAGE SELECTOR switches are set for the proper line
voltage and the correct line fuse is installed in the rear panel FUSE
holder.
Voltage selection switches on the rear panel are used to configure the instrument to operate
on one of four input line voltage ranges. The range of input voltages for each configuration
of the switches is illustrated in Figure 2-1. Set the switches to conform with the line voltage
to be used with this instrument. The switch positions for each input voltage range are in­
dicated on the rear panel and in Figure 2-2.
Verify that the line fuse installed in the fuse holder on the rear panel is the correct fuse (0.5
amps, -hp- part number 2110-0012).
