I designed a new version of the pulse generator, based on the design by Jim William "Pulse Gen"
The main objectives were:
- small size (the overall size of the casing 48x67mm (PCB 42x59mm)
- low cost
- easy accessibility to the elements (including the transistor 2n2369A)
specification:
Rise Time 250 - 300 ps
Vp-p 8-10 V
pulse repetition - 5-15 us
To power the system, I use CR2450 batteries, current consumption of the gen does not exceed 3mA. This should provide approximately 100 hours of work.
Project is easily upgrade to the version of the SMA connector.
If someone is interested, I can arrange several sets (all componenst + casing for your own soldering - set of parts) or ready-soldered ready to use
