Chapter 4, Periodic Adjustments

Introduction

N:\mkt\MANUALS\HP8924C\ALR\per_adj.fb

Audio Analyzer 1 Offset 

Two DC offsets are measured and downloaded as calibration factors to the Audio 
Analyzer 1 assembly: 

1. Input Select Switch grounded 

2. Audio Input selected with return conductor grounded 

Variable Frequency Notch Filter 

The calibration factors for tuning the variable-frequency notch filter are 
determined: The input to the filter is set to 10 evenly-spaced frequencies between 
300 and 10 000 Hz. The DAC that tunes the notch filter is adjusted for best null of 
the tune error voltage. From this data, three coefficients of a parabola which best 
fit the tuning data are calculated using a least-squares curve fit. The coefficients 
are then downloaded into the Test Set’s non-volatile memory.
