00:09 – Introduction & Giveaway Details
02:21 – Leo Bodnar Electronic – Fast Pulse Generator

These fast pulse generators are rated to below 25ps! The modules are examined and various microwave and design considerations are explored. The block diagram and functionality of the final output driver is also described in details. The units are used to measure the rise and fall time of various oscilloscopes ranging from 300MHz to 13GHz of analog bandwidth. You can purchase your own fast pulse generator here.

21:11 – SV1AFN GPS Disciplined Oscillator

This GPS disciplined oscillator not only provides frequency synchronization to the GPS clock, it also provides programmable outputs on two independent channels using a Silicon Labs synthesizer IC. The complete module acts as standalone unit which only requires power and GPS antenna connection. The full schematic and block diagram of the synthesizer chipset is presented along with measured output waveform, frequency an phase noise at 1GHz. You can purchase your own GPS DO here.

33:28 – Sain Smart USB-C TS80 Portable Soldering Iron

This soldering iron which supports QC 3.0 is the followup of the very popular TS100 soldering iron. The unit can operate with up to 18W of power from 9V. However, it does not support PD on USB-C. By using the AVHzY USB tester the power bank can be configured to provide any desired output voltage and deliver up to 28W into the TS80 soldering iron. Using this method, the TS80 soldering iron can easily solder large components on a wide ground plane. The TS80 soldering iron can be purchased here or internationally from here. The Ankar PD+ 28600mAh power bank can be purchased from here and the AVHzY USB tester can be purchased here.

    hi,
    Thanks again for the very helpful educational uW & EE tutorials!

    Very nice demonstration of the Leo Bodnar GHz pulser, which would be helpful for my amateur experiments in radio astronomy.
    I am saving up to purchase one.

    — However, it is very difficult to be able to afford any of the GHz scopes and SA’s that you happen to have,
    So, am wondering if you might be able to help us with some recommendations for older GHz scopes that we can afford,
    say on eBay such as the Tektronix 1180x or the HP 54710, HP 54720d type scopes.

    Do you think that you could help us get started with some demonstrations, repairs and discussions with the older, more affordable equipment,
    so that we can at least get started at the bench, until we can save & then afford nicer newer GHz equipment ?

    thank you,
    rick
