Boonton 4540 Series RF Power Meter
Installation 2-3
Trigger Most triggered applications can use the RF signal applied to the sensors for triggering. For measurements
requiring external triggering, connect the external trigger signal to the EXT TRIGGER BNC connector on
the rear panel.
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 USB control, the rear panel USB
connector should be used, and for Ethernet control, connect to the rear panel LAN connector. In most
cases, it will be necessary to configure the interface using via the System > I/O Config 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. Press the lower half (marked "0") of the power switch in the center of the power module on the rear panel.
2. Connect the AC (mains) power cord to a suitable AC power source; 90 to 260 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.
3. Press the upper half (marked "1") of the power switch in the center of the power module on the rear panel. If the
instrument was last in the standby state, it will enter standby mode. If it was last ―on‖ when power was removed, it will
return to the ON state.
4. If the 4540 is in standby mode (no display or power indication present), press the green ON/STBY key (marked with the
international 0/1 on/standby symbol) on the front panel to turn the instrument on. The display backlight should turn on
and there will be several clicks as the instrument boots.
5. After a self-check, the instrument will execute the application program. A bootup splash screen should briefly appear
that shows the instrument name, model number, and software version, and indicates boot status. After several moments
a screen similar to Figure 2-2 should be displayed.
