![]() If you’re measuring how well a device performs at 100 kHz or 1 GHz, this is what you need. The spectrum analyzer receives the signal coming from the tracking generator, through the device under test, and puts lines and numbers on the screen. The tracking generator generates a signal, which is fed through the device under test. ![]() Ted’s Rigol spectrum analyzer consists of two basic parts. These problems can be corrected, though, with a little bit of cunning from Ted: The noise floor was higher than it should have been. Being the first revision of the hardware, there were a few problems there was leakage that would affect the measurement. It was their first revision of the hardware, and it was only a scalar network analyzer. Around the time Ted’s project began, Rigol released their cheap spectrum analyzer, the DSA815. These allow for RF measurements, but if you ever need one, be prepared: you can spend twenty thousand dollars on a used VNA. Ted’s talk begins with a need for a network analyzer. ![]() It comes from Ted Yapo, it is indeed a tale of hardware heroics: what happens when you don’t want to spend sixty thousand dollars on a vector network analyzer? We also have a peer-reviewed journal with the same goal, and for the 2018 Hackaday Superconference we got a taste of the first paper to make it into our fully Open Access Journal. The Hackaday Superconference is all about showcasing the hardware heroics of the Hackaday community. ![]()
