Front-Panel Key Reference
File
NOTE If you wish to compare two saved traces, place traces in view mode
before saving them. This prevents the trace from being rewritten based
on a state change from subsequent loads.
Limits Displays all limits files you may wish to
load to determine whether a trace has
exceeded preset specifications (.LIM).
Limit sets can hold up to 200 points.
Limits can only be loaded individually.
Key Access:
File, Load, Type
NOTE When loading Limits files, be sure you have selected the appropriate
X Axis Units: frequency or time (
Display, Limits, X Axis Units). If you are
in time X-Axis Units, and you load frequency limits, all current limit
line data will be erased and the analyzer will switch to frequency units.
The reverse of the this situation also holds true.
Corrections Displays all corrections files you may
wish to load (.CBL, .ANT, .OTH, .AMP).
Corrections provide a way to adjust the
trace display for preset gain factors
(such as for cable loss). A correction set
may hold up to 200 points.

Destination
When
Type
is set to
Trace
, Destination allows you to
direct your data to
Trace 1, Trace 2, or Trace 3. If the data
is for all three traces (for instance,
Source was All when
they were saved), the data will be returned to the
original trace registers.
