Do you need to measure it on the air? What frequency is the Tx? Is there a sample port on the transmitter?

Regards

I have a 8566 and I need to sample the signal of a 100W FM transmitter. I haven't seen the transmitter but I was told the following below.

Take a piece of wire and attach it to the end of the cable that will go to the 8566. One end will go to the center conductor and the other will go through a resistor to the shield of the cable. This wire will loop once around the transmission line. So far I made two various wires, one with a 400 ohm resistor and another with a 200 ohm resistor. I will take a 2W attenuator with me for good measure. Any thoughts on this, thanks. I ask this as I'm being cautious about the input level to the 8566 as I know it doesn't take much to destroy the front end of a spectrum analyzer. Thanks
