8 Frequency Scan Measurement
Meas Setup
Build From Trace
Builds a limit using an existing trace. This command will overwrite all data in the limit. Since a straight copy
would typically have hundreds or thousands of segments, the data will be approximated to better
represent a limit line; small excursions whose width is less than 10 trace buckets will sometimes not be
captured. Secondary parameters that are not associated with traces (Description, Associated Trace, Type,
Margin, Interpolation, Relative to CF/RL) will be unchanged.
When taking a trace in order to build a limit, it will often work well to take the trace with a resolution
bandwidth wider than the expected measurement, a video bandwidth lower than the expected
measurement, and with the detector set to Max Hold or Min Hold.
The limit will be built above the trace. If the trace is constant, the limit should pass after being built.

Example
CALC:FSC:LLIN2:BUIL TRACE1 Builds limit line 2 based on the data in trace 1. This will overwrite
the data in the table editor.

Initial S/W Revision A.07.00
Offset
Enters a menu that allows you to offset the limit trace by a specified frequency, time, or amplitude. The
offsets will be immediately applied to the limit trace for display and failure calculation. The offset can also
be applied to the points in the limit line.

Initial S/W Revision A.07.00
X Offset
Offsets the limit trace by some specified frequency (for Frequency-based limit lines) or a time (for time-
based limit lines).

:CALCulate:FSCan:LLINe[1]|2|...|6:OFFSet:X?
Example CALC:FSC:LLIN:OFFS:X –50MHZ Sets the X axis offset to –50 MHz.
CALC:FSC:LLIN:OFFS:UPD Applies the X axis offset to all points in the limit line, then reset the X axis
offset to zero.
Preset 0 Hz if Limit X-Axis Unit is Frequency
0 S if Limit X-Axis Unit is Time
State Saved Saved in instrument state.
