2. 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.
3. 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.

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. Never attempt to open the instrument casing, disconnect
transmission lines, or otherwise service the meter while RF power is applied
to the system.
Failure to comply with these warnings may result in injury or death to
personnel, and damage to equipment.
Connect the 5541A RF Power Meter INPUT to the RF power
source using torque techniques appropriate for the connector
type.
Allow 10 minutes for the instrument to warm up.
Turn ON the source RF output power. The display will begin
updating immediately. Allow sufficient time for the readings to
stabilize before recording the measurement results.
