EVM Test Setup
The settings for the test equipment shown in Figure 2–1 are described below:
-
Power amplifier capable of dv/dt = 1 V/
µ
s and with at least 1-A current limit
connected to IN (J2) and GND (J3).
-
Function generator capable of generating both a 10-kHz, 1-V
PP
, sine wave
and a 1-V square wave connected to the input of the power amplifier.
-
Oscilloscope with channel 1 connected to IN (J2), and channel 2
connected to OUT (J3). Set the oscilloscope to trigger off of the rising edge
of channel 1 of the oscilloscope.
-
Appropriately sized resistance for desired output current between OUT
(J4) and GND (J3).
Powering up the device, the power amplifier, and function generator results in
oscilloscope plots similar to those in Chapter 3.
