NORMLIZE ON OFF
If a trace math function has been previously activated, turning
NOTE
normalize mode on can deactivate the trace math function.

The normalized reference position may be adjusted
between 0.0 and 10.0 (corresponding to the bottom and
top graticule lines, respectively) using the data keys,
step keys, or knob.
The normalized-reference-position adjustment allows
measured data to be compared to a reference position,
where the difference between the measured data and
the reference position represents the gain or loss of the
device under test.
When normalization is on, two indicators (→ and ←)
appear on-screen to mark the location of the normalized
reference position.
Front-panel key access:
TRACE
Activates (ON) or deactivates (OFF) the
normalization routine for stimulus-response
measurements. The routine subtracts the calibration
trace stored in trace B from the active trace, trace A.
The result is then offset by the normalized reference
position. Results are displayed in trace A. The reference
level value is displayed in dB when normalization is
active.
When normalization is activated, an N appears in the
special functions area at the left side of the display
screen. The REF LVL softkey under
replaced by NORM REF LVL in addition to RANGE
LVL now being available.
If a thru or open/short calibration state does not
correspond to the current state when normalization is
activated (that is, have the same center frequency, start
frequency, stop frequency, frequency span, or amplitude
scale), the error message ERR 902 BAD NORM appears.
This can happen when several open/short or thru
calibrations are performed. The NORMLIZE ON OFF
function recalls the last calibration run. If one of the
earlier short or thru states has been recalled just before
turning the normalization function on, then the current
and recalled states don't match and the error occurs.
