   I'll post progress as I build Chris Bake's SigGen V1 and develop a MOSFET bassed low side switch for it.
   The SigGen is based on the Raspberry Pi Pico 2.

   MOSFET switch (1 channel only) prototype V1 built and in testing.
   The Switch uses the ACPL-W343 Optocuppler and Gate driver chip and offers 5KV of isolation to protect the SigGen.

   Switch and schematic, only one channel is built and is in testing phase.

   At the moment, the two TVS diodes are clamping the HV around 150 volts for testing.
