Section 8 : Improving Dual Channel Measurement Results

Maximizing Dynamic Range

Autoranging to maximize the dynamic range of measurements in the AGILENT 35670A can function on all channels simultaneously. Therefore all capability previously mentioned for single-channel front-end ranging is available for dual- channel operation.

To set up autorange on all channels, follow these steps:

Press the [Input] hardkey.

Press [ALL CHANNELS] softkey (F2).

Select the [CH* AUTO RANGE] softkey (F6)

For signals that are not steady, use CH* AUTO UP ONLY. CH1 AUTO UP ONLY can be used for all channels to set up modal impact testing. To set up this condition:

Press the [Input] hardkey.

Select the [CH* AUTO UP ONLY] softkey (F5).

To set up the same fixed range on all channels:

Press the [Input] hardkey.

Select the [CHANNEL * RANGE] softkey (F3)

Enter the range, either in units of g or Volts.

Dual Channel Averaging

Averaging to reduce measurement variance applies to all channels being measured. Dual channel averaging is set up the same as single channel averaging:

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.
