Ok, let's try this again
I guess the first thing is to determine if the voltage and current sensors track.
This involves taking a series of measurements at TP1 (voltage) and TP2 (current) at various current/voltage levels, while the transmitter is operating.
So, set everything up for normal board operation. This means with no voltage or current, have 0V at TP1 and TP2, and with normal operating current and voltage you get a little more than 3V at TP1, and as close as possible to 3V at TP2.
Now, using the carrier level pot on the PWM generator board, adjust the modulator output voltage. Can you get 50 or 60V output from your modulator without tripping the overload? If so, do so (both 50v and 60V) and measure the voltage at TP1 and TP2 with both voltages.
Do the same thing with 40V output, 40V output and 20V output.
This will tell if the current and voltage values, as the board sees them.
Hope this makes more sense. The previous note was slightly confusing - but I've been involved in a rather intense intense software development project for the past week or so, so the brain is definitely operating in the mostly right brain zone - and left brain functions (such as clear communications) are not getting full airplay
Let us know how the measurements come out!
Thanks and Regards,
