Minimum Hold
Key access:
[TRACE] > {Min Hold}
Maintains the minimum level for each trace point of the
selected trace, and updates each trace point if a new
minimum level is detected in successive sweeps.
View
Key access:
[TRACE] > {View}
Holds and displays the amplitude data of the selected
trace. The trace register is not updated as the analyzer
sweeps. If a trace is deactivated by pressing
Blank
, the
stored trace data can be retrieved by pressing

.
Blank
Key access:
[TRACE] > { Blank}
Stores the amplitude data for the selected trace and
removes it from the display. The selected trace register
will not be updated as the analyzer sweeps. This
function is activated for traces 2, 3 and 4 at power-on
and
Factory Preset
.
Detector
Key access:
[TRACE] > {More} > {Detector}
Selects a specific detector type, or allows the system to
auto select the appropriate detector for a measurement.
For every trace point displayed, there is a finite time
during which the data for that point is collected. The
analyzer has the ability to look at all of the data
evaluated during that time and present a single point of
trace data based on the detector mode. We call the
interval during which data for that trace point is being
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.
