8 Hints for Making Better RF Measurements

Show Description

Signal sources provide precise, highly stable test signals for a variety of component and system test applications. Signal generators add precision modulation capabilities, and are used to simulate system signals for receiver performance testing.

This Keysight Technologies, Inc. guide helps you improve the accuracy of your measurements that involve using RF analog signal sources. You may increase the accuracy of your data by using more than one of the hints in your test setup. 

HINT 1.

Improve Source’s Effective Harmonic Distortion Use a low pass filter at the output of your source to decrease its harmonic distortion.

HINT 2.

Increase Power Level Accuracy Use a power meter to increase the accuracy of the signal level at your device under test (DUT).

HINT 3.

Improve Frequency Accuracy Select the appropriate frequency reference to improve absolute or relative frequency accuracy.
