Menu Selection Purpose/Action
▷ ▷ ▷ OSL Bases Visible When enabled, the Open, Short, and Load traces will
appear on-screen. Disabling it removes them from the
screen, eliminating excess on-screen clutter.
▷ ▷ ▷ Align Base Traces When enabled, the Open, Short, Load, and DUT
traces may be aligned to each other based on the
common part of the beginning of the trace.
▷ ▷ Calibration Standards Brings up a table of Calibration Standard Kit
Coefficients. There is the option to change and apply
the standards.
▷ ▷ S
11
→ USB (.csv) Creates a CSV (Comma Separated Value) file of the
selected S
11
trace and outputs that file to a connected
USB drive.
▷ ▷ Phase Corr. Off/On Toggles the Phase Correction On/Off.
▷ ▷ Phase Corr. Start Using the active time-domain cursor, sets a new start
point for the Phase Correction.
▷ ▷ Between Cursor Off/On/Hold Toggles S
11
Between Cursors mode:
▷ ▷ ▷ Off .......................... Between Cursors Off.
▷ ▷ ▷ On ........................... Between Cursors On – the active section will adjust
with time-domain cursor movement.
▷ ▷ ▷ Hold......................... Between Cursors Hold – the active section will remain
regardless of cursor movement.
▷ Hide Selected Trace Hides the selected trace.
▷ Reapply S
11
Adjusts the time-domain settings to match those used
for the selected live S
11
trace.
▷ Apply Normalization Creates normalized TDR trace based on the selected
S
11
trace.
▷ Cable Loss Changes selected S
11
trace to Cable Loss
(S
21
/insertion loss) trace. Terminate cable with
precision short adapter for meaningful results.
▷ Smith Chart Toggles Smith Chart display for selected complex
division FFT or S
11
trace.
Layer Peeling Creates layer-peeling trace from selected trace.
Assumes active cursor (layer peel start) is set at
50 ohms.
Hide Selected Trace Hides the selected trace.
Set Base Sets selected trace as the base (denominator) trace for
math operations.
