Several years ago I tested MOV devices from several manufacturers. All had a
nominal rating of 70 volts and 10 joules. My testing forced breakover with a
10-ohm limiting resistor. Source voltage was 120 mains and simple fill-wave
rectifier. The results were quite inter

I'm interested in using a frequency scanner as a low cost EMI sniffer.
Where can I buy one? (I would probably have to do this through mail order/web
order)
Can someone recommend a source?
thanks in advance

I have seen the combo of a Gas tube in series with a MOV but do not
understand the design considerations.
What I do understand is that Gas tubes have a rather slow action and need
to go through zero crossing to extinguish.
Is the MOV there to help this turn off issue? Why would

The carbon polymer types you refer to (see attached EMail). They have a

are restricted to below 60 volts. I have seen telecom protection circuits

Moshe,
If interested in a really low cost set up, look on page 6.3-1 of Dr. Keenan's
Digital Design for Interference Specification book. Shows how to use an FM
radio with a signal generator and making your own dipole antenna with 300 ohm
TV antenna cable.
