Trace/Detector
More Information
When a trace becomes inactive, the following things happen:
•
Any update from the SENSe system (detectors) immediately stops (does not wait for end of
sweep)
•
the trace is displayed at half intensity (as long as it stays inactive)
Inactive traces display across the entire X Axis of the instrument. Their horizontal placement
does not change even if X Axis settings subsequently are changed, although Y-axis settings will
affect the vertical placement of data.
In most cases, inactive traces are static and unchanging; however, there are cases when an
inactive trace will update, specifically:
•
if data is written to that trace from remote
•
if trace data is loaded from mass storage
•
if the trace is the target of a Copy or participant in an Exchange
•
if the trace is cleared using the Clear Trace function (below)
When a trace becomes active (Update=On), the trace is cleared, the average count is reset, and a
new sweep is initiated.
Traces which are blanked (Display=off) do not display nor appear on printouts but are otherwise
unaffected. They may be queried and markers may be placed on them.
Note that the action of putting a trace in Display=Off and/or Update=Off does not restart the
sweep and does not restart Averaging or Hold functions for any traces.
Note also that whenever you set Update to On for any trace,Display is set to On for that trace.
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
