  3. .. peak value to the signal end of R1, and adjust R8 for zero indication on the meter. Now apply the maximum level I chose +10 dBu and set R11 for full-scale deflection. R8 must be set first, then R11. Temperature stability is good. According ...
    .. D3/R4 bootstrapping R3 to give a linear fall in voltage equivalent to 20 dB in 1.7 s, which, more by happy accident than by design, is exactly what we want. Now we pass the signal through D4, whose tempco of about 2 mV/ C compensates for ...

  5. .. to the PCB including a jumper. Three wires are attached including the +5 V and ground from the USB cable. The other ground wire needs to be soldered to the BNC body. To do this, I had to break out the old Radio Shack 100 W soldering gun to ...
    .. if the final design could attain a 500 ps rise time, this would be too large to ignore as it could give an error in the 10% range. But if we assumed a value for R P (or better yet pre-measured it) we could remove it after the fact. As ...
