Using Markers with Dual Channel Time Measurements

Compare the time trace of Channel 1 with Channel 2 using two techniques: peak tracking and coupled markers. With peak tracking active on both channels, it is possible to measure an event with two channels and easily compare peak amplitudes. Set set up peak tracking for both channels, do the following:

•Press the [Active Trace] hardkey.

•Press the [A] softkey (F1).

•Press the [Marker] hardkey.

• Toggle the [PEAK TRK ON OFF] softkey (F6) until ON is highlighted.

•Press the [Active Trace] hardkey.

•Press the [B] softkey (F2).

•Press the [Marker] hardkey.

•Toggle the [PEAK TRK ON OFF] softkey (F6) until ON is highlighted.

Coupled markers can provide a quick comparison of relative levels during a transient event at a specific time. To set up peak tracking on Channel 1 and force the marker on Channel 2 to the time of Channel 1 peak, do the follow:

•Press the [Active Trace] hardkey.

•Press the [A] softkey (F1).

•Press the [Marker] hardkey.

• Toggle the [PEAK TRK ON OFF] softkey (F6) until ON is highlighted.

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

Peak tracking looks for the maximum positive level in a trace. Therefore do not use peak tracking to determine the maximum absolute amplitude of negative pulses in a time trace.

Section 10 : Measuring Dual Channel Spectra and Time Waveforms

Two signals can be measured and examined in the time and frequency domains simultaneously. To accomplish this, a quad display format must be set up as follows:

First, preset the analyzer:

•Press the green [Preset] hardkey

•Press [DO PRESET] softkey (F1).

This places the analyzer into the default two channel mode. Set up the transducer parameters as described previously, if desired. Then, set up the display for four traces:

•Press the [Disp Format] hardkey.

•Press the [QUAD] softkey (F6).
