AGILENT 35670A

Supplemental Operator’s Guide

If continuous real-time measurements over a long duration are required, and absolutely no overload conditions are desired, then a fixed input range can be set that is greater than any signal expected. During periods of low signal level, dynamic range will not be optimal, however the entire measurement can be completed without overloads. To set up a fixed range of 1 volt:

Press the [Input] hardkey.

Select the [CHANNEL 1 RANGE] softkey (F3), enter 1, then press the [Vpk] softkey (F1).

If engineering units are turned on ([XDCR UNIT ON OFF]) then the range can be specified in EU. For example, if an accelerometer is connected to channel 1 with XDCR UNIT turned on and XDCR UNIT LABEL specified as [g], then the input range can be specified as 4 “g” as per the following:

Press the [Input] hardkey.

Select the [CHANNEL 1 RANGE] softkey (F3)

Enter 4, then press the [EU] softkey (F8).

Averaging to Reduce Measurement Variance

Spectral measurements of steady signals give results which have a statistical variation over time. Averaging several results will help reduce this variation. The AGILENT 35670A has several averaging techniques available. For general spectrum measurements, RMS or power averaging is commonly used. To average a series of ten spectrum measurements using RMS averaging, follow these steps:

Press the [Avg] hardkey.

Press the [NUMBER AVERAGES] softkey (F2), enter 10, then press the

[ENTER] softkey (F1).

Press the [AVERAGE TYPE] softkey (F3)

Press the [RMS] softkey (F1)

Press the [Avg] hardkey.

Turn on averaging by pressing the [AVERAGE ON OFF] softkey (F1) until ON is highlighted.
