Hmm, Perhaps the Tectronix model wasn't really power efficient then, the HPs
model generates fine those finite energy, but infinite amplitude impulses
with two AAA batteries. ;)

Wasn't that Tectronix? I think the model is discontinued by now...

I think it might use a little bit more power than your local power
vendor might appreciate, as well...

Ravirevolt, we are kidding. The pulse train you see in the
mathemathical descriptions of the sampling process are
merely mathematical idealizations (some would say
obfuscations) of a simple technical process. Try to google for
"sample and hold ADC" to find out how sampling is really
performed.

One way is to connect the trigger of an infinite impulse generator (I
think HP makes one) to a square wave signal generator with the desired
sampling frequency. You should ensure the cables you're using are
well-shielded as the IIG generates lots of interference.
