Adding E Field Probe - Startup and Operation - not for construction

Thanks for this! Too cool to resist any longer! I just sent my inquiry off to Egon for my kit, as I finally have the time to build and install the setup.

Finally found a big enough carrot, huh?

An 'addenda' added to 1st post above... :oops:

ROTFLMAO!..... :grin:
Yep....big carrot! Perhaps it will partially compensate for my non-functional AS3935!

Mind-bending indeed! Still trying to wrap my head around this....
So?...
- Once I connect the E-field amp to controller input 2, I can no longer set the channel threshold values for Amp 1 independently? Seems odd....
- If the above is true, how does the auto-noise adjust on the H-field amp (1) deal with the situation?
- Channel C thresholds from Amp 1 and Amp 2 are tied together (same ADC)? The firmware allows channel C threshold setting on either Amp 1 or Amp 2 settings? Or, the Channel C setting on Amp 2 must be >= than the channel C threshold setting on Amp 1, but still independently adjustable? Sounds like some firmware work is needed...
- Why 3 channels for the E-field amp? Different points in the filter chain?
Thanks!

Ditto for A and B of Amp 2. Channel C shares the same ADC on both amps, and therefore will assume as its low threshold, the highest threshold of 1 ch C, and vice versa. Since C isn't used on H field, you can check 'Force all Channels On' and adjust amp 2 Ch C and/or Amp 1 Ch C thresholds appropriately. Gains, however are independently adjusted.
So if you cannot lower threshold on E field (Amp 2) channel C, force all channels on, lower amp 1 Ch C, then uncheck force all channels on, and readjust the original A's and B's on both amps to suit.... Channel C on amp 2 should remain at the setting selected. It can be set higher, if memory serves, but not lower... sheesh. And I probably could have explained it better... tough. :twisted:
