INSTRUMENT DISPLAY
The 5541A RF Power Meter digital direct-reading display, shown in Figure 2,
provides forward and reverse power measurements, VSWR, and frequency. These
readings are indicated on the display by the designators FWD PWR, REV PWR,
VSWR, and FREQ respectively. Units of measurement are displayed on the right
side of the display. The displayed measurement data is updated three times per
second. 
NOTE: The Frequency and VSWR indications are informational and provided only for the user’s convenience. For traceable frequency measurements, use appropriate instruments.
CONNECTING THE RF POWER METER AND TAKING YOUR FIRST MEASUREMENT
-
To meet published specifications, allow the instrument to acclimate in the laboratory environment for at least 24 hours after shipping, storage, or other exposure to temperatures beyond its operating range of 18 to 28 °C.
-
Before connecting your 5541A RF Power Meter to any RF power source, identify the INPUT and OUTPUT ports. The INPUT port and power flow direction are designated by the symbol on the instrument housing (see Figure 3). NOTE: The 5541A RF Power Meter may be calibrated to either the input or output port. However, the RF power source must always be connected to the input port regardless of which port is calibrated. Failure to do so may result in incorrect readings. Refer to the Calibration Certificate for port calibration information.
-
Connect an IEEE 802.3af PoE (Power over Ethernet) compliant device (switch/hub/router/etc.) to the 5541A RF Power Meter The 5541A RF Power Meter display will illuminate.
NOTE: The 5541A RF Power Meter may be connected to any IEEE 802.3af compliant device for power. However, the meter must be connected to the same network as the host PC for communication. -
Connect the 5541A RF Power Meter OUTPUT to a suitable load using torque techniques appropriate for the connector type.
WARNING: High RF power levels may be present at the output of the 5541A RF Power Meter. Always connect an appropriate load to the instrument output.
WARNING: The 5541A RF Power Meter should be serviced by qualified personal only.
