3-7 Trace Cable and Antenna Measurements
3-7 Trace
The Site Master S331L allows the user to concurrently view the live
trace and a second trace that is stored in trace memory. The user can
compare the two traces visually or using trace math functions. Pressing
the Trace (5) main menu key will bring up the trace functions.
Overview of traces:
• Recalled measurements (.dat files) from internal memory or a
USB stick are automatically copied to trace memory and
displayed.
• Copy Trace to Memory will replace whatever is in memory with
the live (yellow) trace. The memory trace (purple) is displayed
behind the live (yellow) trace.
• The default view is live Trace Only. View options (Trace Display)
also include viewing only the trace in memory or both traces.
• View only trace memory to have marker values apply to the
purple trace.
Note
Recalled measurements may change the current instrument
settings.
