TRACE
Accesses the trace keys to store and manipulate trace
information. Each trace comprises a series of data points
in which amplitude information is stored. The analyzer
updates the data for any active trace with each
successive sweep.
Trace
Key access:
[TRACE] > {Trace}
Selects the trace (1-4) for current use.
Clear Write
Key access:
[TRACE] > {Clear Write}
Erases any previously stored trace data and continuously
updates the display during following sweeps of the
analyzer. This function is activated for trace 1 at power
on and factory preset.
Max Hold
Key access:
[TRACE] > {Max Hold}
Maintains the displayed maximum level for each trace
point of the selected trace. A trace point is updated if a
new maximum level is detected in successive sweeps.
NOTE
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.
