5-12 Log Mag Display Types

The MS20xxB VNA Master and the S412E LMR Master can display 1-port and 2-port
measurements (Return Loss and Insertion Loss) in a Single display format (one at a time) or
simultaneously in a twofold display format.
The two types of twofold display are: Dual and Overlay. In Display Type Overlay, two traces
are shown in a single sweep area (refer to
traces are shown in separate sweep areas (refer to
displays are examples that may not match any display on your instrument.

your instrument.
Procedure
1. Ensure that the instrument is in Vector Network Analyzer mode, and that the
Meas Menu soft key is toggled to Field.
2. Press the Measure function hard key, and then press the Display Type soft key.
3. From the Display Type list box, scroll to Dual and press the Enter key.
4. Press the Active Display soft key (if necessary) to select TR1 (Trace 1). Then press the
Measurement Type soft key and select Insertion Loss.
5. Press the Active Display soft key to select TR2 (Trace 2). Then press the
Measurement Type soft key and select Return Loss.
6. Press the Freq/Dist function hard key and set the Start Frequency and Stop Frequency.
7. Press the Sweep function hard key and then the Data Points soft key to set the number
of data points (the larger the number of data points, the longer the maximum distance,
at the expense of a slower sweep speed).
8. Press the Shift key, then the Calibrate (2) key.
9. Press the Start Cal soft key and perform a 2-port OSL calibration.
10. When the Calibration is finished, CAL: ON (OK) should be displayed with the trace data
in the instrument settings summary at the left side of the sweep window.
11. Connect VNA Port 1 and VNA Port 2 to the DUT.
12. Press the touch screen or the Active Display soft key to toggle between the two traces.
13. Use the File menu to save the measurement. Refer to the file management instructions
in the user guide for your instrument.
