For bench-top use, choose a clear, uncluttered area. Ensure that there is at least 2" of clearance at the exhaust vents on the
side panels. Pull-down feet are located on the bottom of the instrument. Rack mounting instructions are provided with the
optional rack mount kit.
2.2 Power Requirements
The 9240 Series is equipped with a switching power supply that provides automatic operation from a 90 to 260 volt, 47 to 63
Hz, single-phase, AC power source. Maximum power consumption is 15W and 25VA. For metric fuse sizes, use the metric
fuse kit supplied. Connect the power cord supplied with the instrument to the power receptacle on the rear panel. See Figure
3-2.
Caution Before connecting the instrument to the power source, make certain that a 0.5-ampere time delay fuse (type
T) is installed in the fuse holder on the rear panel.
Before removing the instrument cover for any reason, position the input module power switch to off (0 =
OFF; 1 = ON) and disconnect the power cord.
2.3 Connections
Probe(s)
Connect the RF Voltage Probe that covers the frequency range of the measurement to the CHANNEL 1
connector on the front (Standard) or rear (Optional) panel, as follows. Connect the probe to the supplied
Data Adapter/Cable combo. Connect the Data Adapter to the CHANNEL 1 Input, holding the red mark on
the adapter connector up. For two-channel measurements, use the same procedures to connect the second
probe to the CHANNEL 2 input.
Recorder If a recorder is to be used to record measurement data, connect the recorder to the recorder BEC connector
on the rear panel. Output impedance is 9.06 kilohms, and the output voltage range is 0 to 10 volts dc.
Remote
If the instrument is to be operated remotely using the GPIB (IEEE-488) bus, connect the instrument to the
bus using the rear panel GPIB connector and appropriate cable. For RS-232 control, the rear panel 9 pin
RS-232 connector should be used. In most cases, it will be necessary to configure the interface used via
the Menu > SETUP > IEEE or Menu > SETUP > RS232 menus.
