2-2

The settings for the test equipment shown in Figure 2–1 are described below:

-

Function generator is set to a triangle wave that ramps from 0 V to 8 V, and
a period of 10 ms.

-

Power amplifier is set to a gain of 3 dB and a minimum slew rate of 5000
V/

µ

s.

-

Power supply capable of 

±

30-V swing and a 0.5-A current limit to power

the power amplifier.

-

A four-channel oscilloscope with channel one’s voltage probe connected
to J1 (IN) and channel two’s voltage probe connected to J3 (OUT). Using
a free channel, connect a current probe around the output load resistance.
Set the scope to trigger off of channel one so that one full triangle is
displayed on the screen.

-

A 66-

Ω

 resistance for 50-mA of output current (or 50-mA electronic load)

connected between J3 (OUT) and J2 (GND).

After powering on the amplifier, the input voltage, output voltage, and output
current is displayed.
