Jason Chonko from Siglent America is joined by Nick KN6NK to give an in-depth intorudction to spectrum analyzers. We talk about the specs, features, and engineering that make up this handy piece of frequency-domain test equipment. We also explore several common spectrum analyzer uses such as filter and cavity tuning as well as radio purity evaluation.

When working with circuits diagnosis and design become nearly impossible if you can’t see what’s going on. Digilent has created a super portable and affordable instrument that when combined with its Waveform software suite, it delivers to its users a bench worth of test and measurement instruments in a USB device slightly larger than a deck of playing cards. George has been a huge fan of this device for a while and suggests that it’s a great option for those who need a lot of capability on a budget or those who need a lot of instruments in a portable package. Join Kaitlyn Franz, Instrumentation Product Manager for Digilent, as she introduces us to the many functions of the Digilent Analog Discovery 2.

Curious about what the “10 MHz” connector on the back of your test equipment or radio is? Interested in calibrating an SDR to reduce tuning error? Do you want an accurate frequency source for tuning radios? How about a super accurate sense of what time it is? This week, Dr. Frank M Howell K4FMH joins Jeremy and George to talk about GPS Disciplined Oscillators and Frequency references for your workbench.

Alan Wolke W2AEW from Tektronix joins us to talk Oscilloscopes. Alan is a field application engineer for Tektronix, the world's most well-known oscilloscope maker. He also has a YouTube channel that is chock full of great information for those wanting to better understanding oscilloscopes and test equipment in general. Alan joins us for a two part session to deep drive on oscilloscope features and applications. In part one, we introduce the oscilloscope, what it's used for, some introductory concepts, and some comparisons of analog and digital scopes. We also discuss probe quality.

George and Jeremy take a look at power supplies for powering radios and working on electronic projects. They explain the differences between traditional radio power supplies and “lab” Constant Current / Constant Voltage power supplies. They also provide helpful tips on what to look for when selecting power supplies for your radio or your workbench.
