Port Richey, Florida, January 24, 2022 – David Goins, founder of and chief engineer
for Windfreak Technologies, has written a number of application notes pertaining
to the specification and testing of RF and microwave frequency signal generators.
Most of the articles include features and applications for Windfreak Technologies
products, but the concepts are universally applicable. His latest, "Testing RF Generators for Reliability" is featured here.

We pride ourselves in designing, building, and selling high value radio frequency
products that are thoroughly evaluated and tested. All of our products go through
rigorous testing before releasing to our customers. Our devices have proven to be
very reliable. In rare cases, we have had a product come back for repair caused
by output amplifier failures. In this post, we explain the testing process we go
through to ensure our high-quality products and the two reasons for output amplifier
failures.
How We Test and Verify Reliability of RF Output To verify that our RF output
design is reliable, we submit several production units of each model to two long-term
tests.
Full frequency range sweeping is performed on the output at maximum RF power
into an open load and a short load. This test is usually run for a full week. Full
frequency range sweeping at maximum RF power is performed directly into the output
of another RF Signal Generator while that generator is generating approximately
+20dBm of RF output power at 1GHz. In the case of the SynthHD, both channels are
directly connected via a short SMA with each channel configured as above. See below.
This test is usually run for a full week. To date, we currently have no RF testing
products that have failed these tests.
