Boonton 9240 Series RF Voltmeter

1.2 Description

The Model 9240 is a DSP (digital signal processor) based RF Voltmeter capable of measuring RF voltage
levels from 200 microvolts to 300 volts (probe dependent) over a frequency range from 10 Hz to 2.5 GHz
(probe dependent). The voltage levels can be displayed in V, mV, dBV or dBmV. When the measured
voltage is across a known impedance (5 ohms and 2500 ohms), the calculated power can be displayed in
dBm or dBW.

1.3 Features

• Software. A 32-bit Digital Signal Processor running control software provides display, I/O and

system memory functions for the instrument. Software updates are easily made using either the
GPIB or RS232 interfaces.

• Alphanumeric Display. The alphanumeric LCD provides clear, unambiguous readouts of the

instrument's setup and measurement values. Simultaneous display of both channels is available in
dual channel mode. A bar graph provides a display of the channel's measured value for nulling
and peaking applications.
