Cable For My Waveform Generator?

K

Ken Williams

I just got a arbitrary waveform generator.

it didn't come with a cable. How do plug the signal into my circuit? Is
there a special coax cable I can use/buy? Can I just use the same type
of leads/cable that I use with my oscilloscope?

Any direction would be great. Can I get an antenna so I can directly
send out AM/FM waves into the air? (it supports AM/FM Modulation).

Thanks.

The specs for the generator should say what the output impedance is.
Match the output impedance with a like cable impedance. If you tell us
the make and model of the generator, we can help more.

This might make you *very* unpopular. On either side of the
international border.

It also might earn you some unannounced visits and confiscation by
government officials.

I have this:

So I have to buy a cable with an impedance that matches what the
generator is using then correct?

The site links to a pdf document, at page 6-6 input and output
impedances are specified I spotted 5K in, 50 ohms out.

Thanks, so now I need cable that is 50 ohms too.

Hello Ken:

At $1,500USD, your Rigol function generator is very impressive. Its
output impedance *is* 50 ohms at the front panel output BNC female
connector, and is so marked at the right of the jack as you can see.

Yes, you would want a 50 ohm coaxial cable, terminated in a male BNC
connector on at least the generator's end. The cable itself is
typically RG-58/U, or from its family.

Please use your generator wisely.

I just noticed that, it says 50 ohms right on the front. It also has a
42Vpk on it. Does that mean the max voltage coming out of the coax will
never be over 42 volts peak to peak?
