Trace/View 25
Agilent N8201A Performance Downconverter Synthetic Instrument Module, 250 kHz to 26.5 GHz 523
Normalize
Displays menu keys that enable you to normalize trace data.
Key Path: Trace/View
Store Ref (1 −> 3)
Copies trace 1 into trace 3. Store Ref (1 −> 3) must be pressed before pressing Normalize
(On). This puts trace 3 in view mode.
Key Path: Trace/View, Normalize
Remote Command:
There is no remote command for this function, however the trace copy command can be
used for this purpose.
Example:
TRAC:COPY TRACE1,TRACE3
Normalize On/Off
On each sweep, the normalized trace (trace 1) is subtracted from trace 3 and the result is
added to the normalized reference level. The display shows the result of the following
calculation in trace 1. This determines the location of the trace on the display, not the
marker reading.
Trace 1 – Reference Trace
− Normalized Reference Level
where trace 1 and the reference trace are in absolute units and the reference level is in
relative units.
The new trace 1 is normalized with respect to the normalized reference level and reference
trace, even if the values of the normalized reference level or reference are changed. This
function remains in effect on all subsequent sweeps until it is turned off.
The normalize function is most useful for applying correction data to a trace while making a
stimulus-response measurement with a tracking source.
For example,
1 Connect the cables and a through line in place of the device to be measured (between
the tracking source and the N8201A input).
Notice that the frequency response is not perfectly flat, showing the response of the
cables, as well as the flatness of both the tracking generator and the N8201A.
2 Press Store Ref (1 -> 3), Normalize On.
