Hi,
I just bought a mini-circuits zx60-8008 amplifier and am experimenting wth
it a little.
I need to find out if I am hooking it up to my Oscope correctly to measure
what is coming out of it. Here is what I am currently doing.
I hook the GND peg to the GND of my power-supply, then the +12 peg to the
+12 of the power-supply.
Then I input a signal into the IN coax jack of the amplifier.
Then I have a short (maybe 2" long) coax cable attached to the OUT jack of
the amplifier, with the insulation scraped off the end so I can attach an
Oscope probe to it.
Then I hook the + probe of my scope the bare center wire in the short coax
attached to the OUT jack of the amp.
And then I attach the GROUND clip of probe to the GND peg of the amplifier.
Then I measure the signal coming out of the amplifier.
So is this the correct setup to do measurements with an oscilloscope?
Maybe I shoud be connecting the GROUND clip of the scope probe to the
outside grounding sheath of the coax attached to the OUT jack of the amp
instead? Does it matter, maybe this is actuall the same as attaching to the
GND peg of the amp - like I am already doing.
This is a basic question about measurement, but I could not find a diagram
anywhere quickly that shows the correct way to do this.
--thx, jw
