Cable and Antenna Analyzer Measurement Guide : Cable and Antenna Analyzer : Trace
Pressing the Shift key and the Trace (5) key brings up the Trace main menu. The trace math menu inside the cable and antenna analyzer supports Trace Overlay features to allow viewing a two traces at the same time. This is useful when comparing a stored trace to a live trace. Trace Math operations include Trace – Memory and Trace + Memory. It is possible to copy a trace to display memory directly from the trace math menu. Traces can also be downloaded from Master Software Tools into the instrument and compared with live traces.
Trace Overlay
The examples below illustrate how the trace overlay feature can be used to compare a trace stored in memory with a live trace.
1. Press Shift and Trace (5) to enter the Trace Menu
2. Press Recall Trace and locate the appropriate trace from the recall menu.
3. Press the Trace Overlay On/Off key to turn it on. The white trace is the recalled from memory trace and current trace is yellow.

Trace Math Example
The example below illustrates how the Trace – Memory feature can be used to compare the phase of two cables.
1. Press Shift and Trace (5) to enter the Trace menu.
2. Connect the device under test (Cable A) and press the Copy Trace To Display Memory key.
3. Remove the first device and connect the second device under test (Cable B).
4. Press the Trace – Memory key to view the difference between Cable A and Cable B.
