Hi,

I hope this is in the right place. I need some advice on a decent RF voltmeter. Need it to use right at 7 MHz. I need actual voltage, not dB. It should go to at least 5000 Volts. This is not going to be used for a physics project.

Thank you very much,

Joe KB0TXC

If you use a "Frequency Selective Voltmeter" you can get that resolution. Irrespective of what units it may be in you can scale it differently. To get the voltage range you desire you can use precision attenuators.

That is how we used to determine signal levels on telephone and microwave carrier systems. Where we needed to know what was going on at a very specific frequency where the were many signals present.
