Getting Started
This chapter will introduce the user to the RFM3000 RF Power Meter. The chapter will identify display organization,
list the configuration of the instrument after initializing, and provide practice exercises for front panel operation. For
additional information, see Section 4 Operation .
3.1 Initialization
The steps below initialize the RFM3000 and prepare it for normal operations. Step 3 should only be performed when you
wish to set the meter operations to a known state. This is typically done when you first power on the instrument or at
the start of a new test.
1. If the main power is off, press the power switch located on the rear panel. See figure 1.2 .
2. Press the key to turn on the RFM3000.
3. After a self-check, the instrument will execute the application program.
– There will be some momentary dialogs indicating application initialization and channel updating.
– After the last dialog the main screen will be on the display.
When selecting a sensor for an exercise or a measurement, be sure you know the power range of
the sensor. Operation beyond the specified upper power limit may result in a permanent change
of characteristics or burnout.
4. Connect the sensor USB cable to the Channel 1 input on the front or rear of the instrument.
– When the sensor is connected or disconnected, the instrument will momentarily show a channel update dialog.
Note:
Connecting the Sync cable from the Multi I/O port on the sensor to the corresponding Sync port on the instrument
for the sensor in use is necessary if using an external trigger or when performing measurements across multiple chan-
nels
5. Use the nagivation keys to navigate the menus.
– The touch screen can be used to navigate the menus.
6. From the Main menu, select the Measure menu, and navigate to the Meas. Settings option.
7. Select Initialize .
– This will load the default operating parameters listed in table 3.1 .
– This table only shows the parameters that are affected by initialization.
