Hi,
I am looking for a small DC probe which is able to measure analouge voltages from 1...25V inside a RF field of more than 300 V/m.
I tried it with probes of Langer-EMV and Teseo. Probes of Teseo are too big (no homogenous field) and those of Langer are only able up to 200 V/m.
Since I have destroyed the second set of 500 EUR I should better ask for alternatives. :-)
Any ideas? Any experiences with other probes? Thank you in advance.

Can you explain the problem better.
A DC meter with low pass filter will ignore the RF.
You could make the probe with series resistnace and the meter a hi z DC input. The resistors will attenuate the RF.

Err...even an analog DC meter can have measurement problems in high RF fields. However, they are better than even tube-based meters, which are far better than any solid state crap^H^H^H^H metering systems. DC measurements are the least problematic, then resistance measurements, and then AC measurements are the nasty hard class. There was a true story of a drunk in a city that heard music and talking; turned out that the fire escape he was sleeping by was vibrating - it acted like a complete radio receiver for the high powered AM transmitter that was only a few miles away.
