How do I capture a pic of what's on my screen??

I'm sweping some test tones through various components-
mustards, Sozos, Mallorys ect
and I would like to save the response curve, but my spectrum analyizer is real time only. I figure a screen shot will do the trick. But I have no idea how to make one.
Little help here???? I'll share what I find out about frequency response....

Hold "Ctrl" then hit "Print Screen" then paste in Word. That oughtta get ya there, George.
BTW, the BEAST ROCKS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

"Alt" + "Print Screen" will capture the current window, "Ctlr" + "Print Screen" will get you the entire screen - and then like Chief said, paste it into Word (or WordPad)
Congrats

That last one was the Sozo .1
this is the Philips .1
Dead on from 40-40k. This graph is .5db resolution.

George, you sure? The title bar says that both were the Phillips.

Yeah,I was trying to save the curve and it saved the graph settings as Philips .1
Here's the .022

How about an Iskra 68k input resistor? Predictably the response starts to drop off around 6K.

Murata 250pf. One of those red, tubular types.
If you haven't figured it out, I got some new test equipment this week.

Interesting. The .1´s seem to have a smoother cut-off in the highs than the .22´s, effectively letting higher frequencies through, but gradually attenuated ? It looks like the .22´s have a sharper Q, if that makes sense talking about components.
Why the difference ?

Here's what's happening with the 470k/500pf mixer componets.

Here's a '69 Dagnall OT with the sweep feeding the secondary. Response measured across 1/2 of the primary.
Predictably flat with such low levels and no loading. I'll figure out how to measure unded load with the core saturated.
I tried loosening the bolts to see if I could change the curve, but again the levels are too low for the core to be affected.
