Installation Note E4440-90318 3

Audio Input, Option 107

Introduction

This retrofit kit adds audio input capability to the PSA series spectrum analyzer.

Audio input provides an additional audio signal path that is completely separate from

the normal RF/IF signal chain. The Audio input has a 100K ohm input impedance, and

the frequency range is 20 Hz to 250 kHz. The high input impedance must be taken into

account when making measurements on low impedance sources. For example, when

making the Audio AC Level measurement on a function generator with 50 ohm output

impedance, the Audio AC Level measurement value returned will be two times the

voltage setting of the function generator.

This additional path provides the hardware that gives Audio Distortion, Audio

Frequency, Audio AC Level, and Audio SINAD measurement capabilities to the PSA

series spectrum analyzer. Once the hardware is installed, it is mandatory to update the

PSA firmware so the PSA can recognize the new hardware.
