Section 7 : Measuring Dual Channel Spectra

This section contains procedures for setting up and measuring a dual channel spectrum using an AGILENT 35670A Dynamic Signal Analyzer. Procedures are similar to those in the section “Measuring Single Channel Spectrum,” however display setup and results are different and will be described here.

To set up the analyzer for a dual channel spectrum measurement, proceed as follows:

Presetting the Analyzer

Press the green [Preset] hardkey

Press [DO PRESET] softkey (F1).

Press the [Pause/Cont] hardkey if desired.

Selecting Dual Channel Operation

Measure two signals with the default two-channel instrument mode. If the analyzer has been changed to 1 or 4 channel operation, then follow these steps:

Press the [Inst Mode] hardkey

Press [CHANNELS 1 2 4 ] softkey (F7) until 2 is highlighted.

Selecting Frequency Span

Reduce the span to 800 Hz as follows:

Press the [Freq] hardkey

Enter 800 and then press the [Hz] softkey (F2)

Displaying Dual-Channel Power Spectrum Measurements

To see the results of a dual-channel measurement, the analyzer’s display format must be changed to display two traces. Proceed as follows:

Press the [Disp Format] hardkey.

Press the [UPPER/LOWER] softkey (F3)

Press the [Active Trace] hardkey.

Press the [A] softkey (F1).

Press the [Meas Data] hardkey.

Press the

[CHANNEL 1 2 3 4] softkey (F1) until 1 is highlighted.

Press the

[PWR SPEC CHANNEL 1] softkey (F3)

Press the [Scale] hardkey.

Toggle the [AUTOSCALE ON OFF] softkey (F1) until ON is highlighted.

Press the [Active Trace] hardkey again.

Press the [B] softkey (F2).
