Background

I learned about this while watching YouTube videos by the Naval Postgraduate School (NPS). Whenever the HP 33120A 15 MHz Function/Arbitrary Waveform Generator was used to drive a speaker or other device this amplifier was used to raise the output power enough to so that the device would work. One happened to be on eBay when I looked and was at a reasonable price.

In some NPS videos a series resistor is inserted in series with the lower right ground terminal so that both voltage and current across the DUT can be measured. Usually with a dual channel scope.

Description

Frequency range DC to 1 MHz with gain adjustable between 0 and 10X with up to 20 Volts peak output (10 Watts). Can be used a power amplifier or power supply.

Used at the Naval Post Graduate School (NPS) to test SONAR transducers.

PH4454 Experiment 4 Part 2 - Connection to amplifier adds a resistor in series with ground terminal to allow measuring impedance - using ITC-5292 as Tx & F-33 as Rx - ITC-5292 as Tx & B&K (very small) Hydrophone as Rx -
