Review: TPI Version 4 4400 MHz RF synthesizer

Earlier, I wrote a short review on a low cost RF synthesizer from Trinity Power, Inc. (TPI) Version 5, a very small, but relatively powerful RF source that could be used for localized radiated immunity pre-compliance testing of products. The company also sells Version 4, a larger RF synthesizer that sacrifices maximum RF output level for a flatter RF output response. I had a chance to try it out recently. Read More...

Review: Signal Hound BB60C real time 6 GHz spectrum analyzer

The Signal Hound series of spectrum analyzers are about as small as three large-size Hershey chocolate bars stacked on top of each other. The unit offered for review is the recently released model BB60C real time analyzer, which can tune from 9 kHz to 6 GHz with a dynamic range of +10 to approximately -158 dBm (DANL, which is dependent on resolution BW). It can easily fit within a standard briefcase with room left over for a medium sized laptop. Read More...
