Traces, Channels, Windows, and Sheets on the Analyzer

It is critical to understand the meaning of the following terms as they are used on the analyzer.

Other Quick Start topics

Traces

Traces are a series of measured data points. There is no theoretical limit to the number of traces. However, the practical limit is the maximum number of windows times the maximum number of traces per window (24).

In addition, one memory trace can be stored and displayed for every data trace. Learn more about Math / Memory traces.

Trace settings affect the presentation and mathematical operations of the measured data.

The following are Trace settings:

Managing Traces

How to Add a trace

The only measurements that can be selected are those in the same measurement class as is currently assigned to the channel. To select a measurement other than these, first select the appropriate measurement class to a new or existing channel. Learn how.

A trace must be selected (active) before its trace settings can be changed.

How to know which trace is Active?

Using Hardkey/SoftTab/Softkey

Using a mouse

  1. For Traces 1-7, press Trace > Trace 1-7 > click left side Trace 1-7 small button
    (Example: Click on left side Trace 1 small button and Trace 1 is active when it turns green, so Trace 1 added).

  2. For Traces 8-15, press Trace > Trace 8-15 > click left side Trace 8-15 small button
    (Example: Click on left side Trace 9 small button and Trace 9 is active when it turns green, so Trace 1 is added).

  3. Another method of adding traces is by pressing Trace > Trace 1-7 > New Traces....

  4. For other traces numbers, press Trace > Trace Setup > Add Trace, then select New Trace, New Trace + Channel, New Trace + Window, New trace + Channel + Window, or New Traces....

  1. Right click in the grid box and then select New Trace....

Trace Max

How to maximize the active trace - the active trace is the ONLY trace on the screen display. All other traces are hidden.

Using Hardkey/SoftTab/Softkey

Using a mouse

  1. Press Trace > Trace Setup > Trace Maximize (ON). With Trace Max (ON), select a different trace to make that trace visible.

  2. To make all traces visible again, select Trace Maximize (OFF).

  1. Trace > Trace Setup > Trace Hold > OFF | Max | Min.

  2. Restart resets the trace.

Using a mouse

Not available

Maximum/Minimum trace hold can be applied with several conditions:

Channels

Channels contain traces. The analyzer can have up to maximum 500 independent channels.  

Note: Actual maximum number of channel depends on the setup. A large number of NOPs and traces limit the maximum number of channel.

Channel settings determine how the trace data is measured . All traces that are assigned to a channel share the same channel settings. A channel must be selected (active) to modify its settings. To select a channel, click the Trace Status button of a Trace in that channel. The following are channel settings:

Managing Channels

How to Select a Channel

A channel must be selected (active) before its settings can be changed.

To make a channel active, select a trace in that channel or click the Trace Status button of a Trace in that channel.
