So with some raspberry pi jankiness I can generate a 200Mhz signal
TM. This is really the limit of what you can get out of the GPIO pins on a raspberry pi, so things are a lot wonky...
However, if we only look at the voltage measurements on my DSOX1102G - 200Hz signal gives us 4.5 volts.
Things get really wonky at high frequencies - the raspberry pi really doesn't like generating this signal... But, we can see some interesting voltages:
Stock Firmware: 2.38V -- That's a loss of ~5.5dB
Unlocked Firmware: 3.43V -- That's a loss of ~2.4dB
So it looks like the DSOX line can natively do over 200Mhz with only software tweaks - no hardware mods needed... We just need to figure out unlocking 200Mhz while retaining access to licenses - modded software removes all licensed options and can't install any new ones (reverting to stock software re-enables these). Additionally - the modded software removes the limits on the wave gen (Can set crazy values like 200Mhz pulse) - but doesn't actually output any signal
