10 Monitor Spectrum Measurement
Trace/ Detector
Min Hold
In Min Hold type the analyzer maintains and displays a min hold trace, which represents the minimum data
value on a point-by-point basis of the new trace data and previous trace data.
Pressing the Min Hold key for the selected trace, or sending the :TRAC:TYPE MINH command for the
specified trace, sets the trace type to Min Hold, causes the trace to be cleared, and causes the Min Hold
sequence to be (re)started, even if you are already in Max Hold.
Pressing Restart does not restart the Min Hold.
When in Min Hold, if a “Force restart” setting is changed, the trace is cleared and a new sweep is initiated.

Preset After a Preset, any trace that is in Min Hold is cleared (all trace points set to maxtracevalue).
State Saved The type for each trace is saved in Instrument State
Initial S/W Revision A.13.00
View/Blank
This key lets you set the state of the two trace variables, Update and Display. The four choices available in
this 1-of-N menu are:
• Trace On: Update and Display both On
• View: Update Off and Display On
• Blank: Update Off and Display Off
• Background: Update On, Display Off (this allows a trace to be blanked and continue to update “in the
background”, which was not possible in the past)
A trace with Display Off is indicated by a strikethrough thru the type letter in the trace annotation panel in
the Measurement bar. A trace with Update Off is indicated by dimming the type letter in the trace
annotation panel in the Measurement bar. So in the example below, Traces 2 and 3 have Update Off and
Display Off.
See "Trace Update State On/Off" on page 870.
See "Trace Display State On/Off" on page 870.
See "More Information" on page 871.
