Boonton 4240 Series RF Power Meter
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.
2.4 Preliminary Check
The following preliminary check verifies that the instrument is operational and has the correct software installed. It should
be performed before the instrument is placed into service. To perform the preliminary check, proceed as follows:
1. Connect the AC (mains) power cord to a suitable AC power source; 90 to 264 volts AC, 47 to 63 Hz, with a
capacity in excess of 75 W. The power supply will automatically adjust to voltages within this range.
2. Attach the sensor data adapter(s) to the front panel CHANNEL connector(s).
3. Set the POWER switch to the ON (1) position.
4. Verify that "BOONTON ELECTRONICS, 4242 RF Power Meter, REV XXXXXXXX" is momentarily
displayed where XXXXXXXX represents the revision code. (Note: Model number 4241 display for single
channel instruments.) While the sign-on screen is displayed the phrase “ A WIRELESS TELECOM GROUP
COMPANY” is scrolled along the second line.
5. Verify that the measurement display showing "CH 1" only for Model 4241 or "CH 1" and "CH 2" for Model
424
