Trace/Detector
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 3, 4, 5 and 6 have Update Off
and Traces 4 and 6 have Display Off.
See “Trace Update State On/Off” on page 1309.
See “Trace Display State On/Off” on page 1309.
See “More Information” on page 1309.
Couplings Affected by Average Type and Average/Hold Number.
Whenever you press Min Hold or send the equivalent SCPI command, Update
is set to On and Display is set to On.
Automatic detector selection and the VBW:RBW ratio auto rules both depend
on the trace type selections.
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
