dScope Configuration:

Frequency Response Track 19.dsc

Track Number:

Corresponding AP Test File:

2_frqswp.at2

.ac3 Test File:

Duration:

60 sec

Test Signal Description:

20Hz to 20kHz sweep at –20dBFS

Description

This test plots the frequency response of the

EUT

at –20

dBFS

Method

Click the

[OK]

button to start the test, and then play Track 19.

The dScope senses the 60 logarithmically-spaced frequencies on the test track, measures the

amplitude at each (using a band-pass filter to exclude noise), and produces a plot of the results for

both channels. Note that the output scale is referenced to the nominal –20dBFS level of the test

stimulus.
