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 information for
any active trace with each sweep.
If you have selected Channel Power, OBW, or ACPR
in the MEAS menu, refer to “One- button Power
Measurement" on page 43.

the sweep of the analyzer. This function is
activated for trace 1 at power on and factory
preset.

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
