Mohr CT100B Series - Working with Traces; Select a Trace; Scan Progress Display with Cancel Button

4. Operating Instructions
A scanned trace is created using the smoothing factor that is set at the time of the scan. Because
of this, high-resolution or highly smoothed scans may take a long time. During a lengthy scan, a
menu will appear with a Cancel option. See Figure 4.19. Select Cancel to abort the scan.

4.9. Working With Traces
4.9.1. Select a Trace
The CT100B always shows one trace on the screen in bold. This is the selected or active trace. If it
is a live trace, the VERTICAL POSITION and VERTICAL SCALE knobs can be used on the
selected trace, leaving other traces on the screen unchanged. If the selected trace is not a live trace,
you can also use the Save, Rename, and Hide Selected Trace options on the Scan menu without
affecting other on-screen traces. Vertical measurements such as reflection coefficient, return loss,
and impedance are always based off of the selected trace and may disappear if the cursor scrolls
beyond a scanned boundary or is off-screen.
Press the SELECT button to change which trace is active. Figure 4.20 shows a screen with three
traces, and the live trace is selected.
