Trace
The trace functionality enables a reference trace to be stored and recalled, allowing for a
previously stored trace to be compared against the latest measurement trace. Data in the buffer
will be displayed in yellow, the trace will be blue.
Once
Trace
has been selected, the trace menu
①
will be active.
NOTE
This can be very useful when comparing two DUTs (device under test) to see the difference in
performance between the two. One reference trace can be stored at any given time.
The trace menu gives the following options –
Save
– Store the existing latest measurement graphical waveform as the reference trace.
Load
– Recall and display the previously saved reference trace.
Disable
– Stop viewing the loaded reference trace.
The loaded reference trace appears in blue on the same graph as the latest measurement trace.
NOTE
When recalling a trace, the graph auto-scale will ensure both the recalled trace and the latest
measurement trace are visible on the display regardless of difference in levels.
