2-3 General Measurement Setup High Accuracy Power Meter (Option 19)
2-4 PN: 10580-00492 Rev. B High Accuracy Power Meter MG
2-3 General Measurement Setup
Field Master Series instruments display the power values in both dBm and Watts, and offers the following
measurement features:
•Relative Power displays power changes with respect to a desired reference value in both dB
and % (percent).
•Limit values can be turned on as needed to indicate if a measurement is within or outside specified
limits.
•Averages provides a settable number of a running average count.
•Max Hold retains the highest power level measurement.
•External Gain and Loss setting allows power level compensation for passive losses (such as cable loss or
attenuators) or active gains (such as RF power amplifiers).
•Zeroing the sensor improves accuracy by removing measured system noise. Refer to Table 2-2 for the
power range in which accuracy is improved. Calibration factors can be used to correct both efficiency and
mismatch loss.
Caution
Ensure the power level that you are measuring does not exceed the input rating of the power sensor
being used or damage may result. Additional attenuators can be used to ensure that the power does
not exceed the specified measurement range.
Table 2-2. Power Range for Improving Accuracy via Zeroing to Remove Noise
Sensor Power Range
MA24104A +3 dBm to +13 dBm
MA24106A, MA24108A, MA24118A, MA24126A –30 dBm to –40 dBm
MA24208A, MA24218A –45 dBm to –60 dBm
MA24330A, MA24340A, MA24350A –50 dBm to –70 dBm

High Accuracy Power Meter (Option 19) 2-3 General Measurement Setup
High Accuracy Power Meter MG PN: 10580-00492 Rev. B 2-5
Example Measurement Setup
This measurement example uses an Anritsu MA24106A power sensor and an attenuator for a high power
measurement.
1. Connect the USB cable between the sensor and your instrument. When the sensor is connected, a
notification in the top toolbar will identify the sensor model number.
2. Press the On/Off key to turn on your instrument.
3. Select the High Accuracy Power Meter by touching the 9-dot icon or from the current measurement icon
to display the available analyzers (see Figure 2-4). Select the HIPMUSB application, then touch the
desired analyzer icon to load the new analyzer.
4. Open the Zero/Cal menu and enter the Cal Frequency, or press Signal Standards to select a particular
standard. Calibration factors are stored in the power sensor for the corresponding measurement
frequency.
5. With sensor RF input connector disconnected from any other device, press Zero to zero the sensor. This
step is recommended when making power measurements below –20 dBm.
6. Open the Amplitude menu and enter the EXTERNAL LOSS value of the attenuator.
7. Connect the power sensor to the RF output of the device to measure and read the power level on the
instrument display.
Figure 2-4. Example Analyzers
Note When using a signal standard, the channel number is not required because the calibration factor
frequencies are rounded to the nearest 500 MHz.
Note
With no loss or gain offset, the maximum value for the display is the upper measurement range,
which is +20 dBm. With an offset, such as with 10 dB of attenuation, the upper value can be set to
+30 dBm. With an offset of xx dB, the upper value can be set to +20 dBm plus xx dB.

AVERAGES: Sets the number of measurements to be averaged.
MAX HOLD: Sets the displayed measurement to show the maximum measured power
when enabled, and places a marker on the scale at the maximum measured value. Note
that changing any parameter resets this feature. If averaging is selected
(AVERAGES > 1), then Max Hold displays the maximum value of non-averaged data.
MEAS MODE: Sets the measurement to Continuous or Single mode. Continuous will
cycle through the average count continuously. Single will cycle through the average count
just once and then switch to Hold mode. Single measurements must be triggered each
time by using the Single button below.
RUN/HOLD: Sets the current measurement to Run or Hold. In Run mode, the power
meter takes measurements according to the MEAS MODE setting. In Hold mode, the
power meter finished the current measurement and then stops measuring.
SINGLE: Triggers a measurement when the MEAS MODE is set to Single.
