| specifications | prices
TeachSpin's PAA1-A is truly a "Utility Infielder" for the lab, be it research or teaching.
Originally designed to support the Signal Processor/Lock-In Amplifier
for experiments requiring large modulating currents, it has become an
indispensable workhorse for a wide variety of tasks. We guarantee that
if you buy one for the student lab you will find yourself borrowing it.
The compact instrument has a response all the way from DC to past 20 kHz
and is capable of output currents of one ampere. This is a true bipolar
amplifier, able to drive its output above or below ground potential, and
to hold it at the desired potential.
