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.
