Chapter 11 — High Accuracy
Power Meter

11-1 Introduction

The VNA Master with Option 019 is available on all VNA Master models and sensors PSN50
or MA24106A can be used to make High Accuracy Power Measurements from 50 MHz to
6 GHz. This high performance sensor option provides true RMS measurements with accurate
measurements for both CW and complex digitally modulated signals.
A power sensor is not included with Option 019. PSN50 or MA24106A sensors
Note
must be ordered separately.
The power values are displayed in both dBm and Watts. The Relative Power feature allows
the display of 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. Running averaging and a Max/Hold feature are also available.
The VNA Master connects to the PSN50 High Accuracy Power Sensor or MA24106A USB
Power Sensor with a standard USB A/mini-B cable (3-2000-1498).
The zeroing feature improves the accuracy at low power levels by removing measured system
noise. Calibration factors can be used to correct both efficiency and mismatch loss.
Attenuators can be used to ensure that the power does not exceed the specified measurement
range. The Enter Offset feature allows entering offset values for any cables and attenuators.
