Preparing the Analyzer for Use
This chapter contains instructions for inspecting and installing the
HP 89410A DC-10 MHz Vector Signal Analyzer. This chapter also
includes instructions for cleaning the screen, transporting and storing the
analyzer.
Power Requirements
The analyzer can operate from a single-phase ac power source supplying
voltages as shown in the table. With all options installed, power
consumption is less than 750 VA.
AC Line Voltage
Range Frequency
90-140 Vrms 47-440 Hz
198-264 Vrms 47-63 Hz
The line-voltage selector switch is set at the factory to match the most
commonly used line voltage in the country of destination; the appropriate
fuse is also installed. To check or change either the line-voltage selector
switch or the fuse, see ‘’To change the line-voltage selector switch’’ or ‘’To
change the fuse.’’
Warning Only a qualified service person, aware of the hazards involved, should
measure the line voltage.
Caution Before applying ac line power to the analyzer, ensure the line-voltage selector
switch is set for the proper line voltage and the correct line fuse is installed in
thefuseholder.
