TRACE
Accesses the trace keys to store and manipulate
trace information. Each trace is comprised of a
series of data points in which amplitude
information is stored. The analyzer updates the
information for any active trace with each sweep.
If you have selected
Channel Power, OBW, or ACPR
in the
MEAS menu, refer to
Trace
Selects the trace for current use.
Key Access:
[TRACE]
Clear Write
Erases any data previously stored in the selected
trace and continuously displays any signals during
the sweep of the analyzer. This function is
activated for trace 1 at power- on and Factory
Preset.
Key Access:
[TRACE]
Max Hold
Maintains the maximum level for each trace point
of the selected trace, and updates each trace point
if a new maximum level is detected in successive
sweeps.

Changing the vertical scale (Amplitude, Scale Type, Log or
Line), or pressing PRESET, or turning averaging on (TRACE,
Average (On)) or switching widow in Zone Span restarts the
held trace.
