The Standard Test Wizard is used to set up tests, embedding/de-embedding, calibration, and measurement results. These set ups can be saved for later use.
Note: The Standard Test Wizard is not compatible with DCA and E5071 instruments.

The File pull-down menu is used to save a test that was set up using the Standard Test Wizard, open an existing setup, create a new setup, or exit the wizard. Selecting New will clear the Standard Test Wizard of all settings.
|
The test setup summary is displayed in the top part of the Standard Test Wizard dialog as shown below.
The test setup summary information is defined in the Welcome to PLTS dialog, which is part of the Startup Wizard. Test setups can be saved/loaded from this dialog. Learn more.

The Next/Back buttons can be used to move through the selections shown in the navigation pane.

The Select Standard dialog is used to set up the DUT configuration.
Expand the folders in the Standard pane to select an existing standard. The following example shows the settings with the Default 8-Port standard selected.
Frequency Start - Sets the start frequency of the sweep. Frequency Step - Sets the step size between points. This value is normally locked to (is the same as) the Frequency Start value. Frequency Stop - Sets the stop frequency of the sweep. Number of Points - Sets the number of measured points per sweep. Note: PLTS requires at least 11 data points. This limitation also exists when loading Cal Sets. New button - Creates a new standard under one of the existing categories (click on the down arrow) or creates a new standard under a new category.
Delete button - Deletes the selected standard. Import button - Imports a previously saved standard. Export button - Exports the selected standard.

The Define DUT dialog allows the selected standard for the DUT to be edited.
1. Enter the number of DUT ports to calibrate and measure - Beginning with PLTS 2018, the maximum number of DUT ports is 64. Or click Load to recall a previously saved configuration (*.dcf) file. Description - File name of the current configuration. Change this text, then click Save As to store the current configuration to a *.dcf file using this file name. VNA Port - Change the VNA port number. The E5071C ENA has some limitations that must be considered. See E5071C Limitations. Port Label - For the PNA/ Single-ended DUT port. The text replaces input and output arrows (<<<< and >>>>). DUT Port
Logical Port - For differential pairs, the logical port is comprised of two DUT ports. For single-ended ports, the logical port can be a different number than the DUT port. DUT Cfg
Save As button - Store the current configuration. This file can later be recalled using the Load button. Reset button - Recall the Default Configuration. Cancel button - Discards the changes you made since open the dialog and closes the dialog.

Select a calset that is currently stored in the VNA from the Existing Calibration Data list.

The Perform Measurements dialog is used to set up post measurement processing.
Change Measurement Settings - Check to allow setting changes. Averaging - Sets the number of averages. Each data point of consecutively swept traces is mathematically averaged until the total number of sweeps is equal to the averaging factor. This effectively lowers the noise floor, but also slows the measurement time. IF Bandwidth - Sets the IF bandwidth. Narrower (smaller) IF bandwidths lower the noise floor so that low-level signals can be viewed, but slows the measurement time. Rise Time - Sets the transition time (in ns) of the stimulus signal rising from 10 to 90% of the maximum signal amplitude.

The N Port Reference Plane Adjustment to remove unwanted effects from the measurement.
De-embedding/Embedding Tab De-embedding - Mathematically removes the effects of characterized device, such as an adapter or fixture, from the measurement. Embedding - Mathematically adds the effects of the characterized device to the measurement. SnP file name - Selects/Loads a SnP file to embed or de-embed. Click on the "..." button to load a file from a local directory or click on the down arrow to select a previously loaded file. Reverse De-embedding File - Check to reverse, or 'mirror' the device port numbers as they are applied to the DUT port. Add Specified Adjustment button - Adds the currently selected SnP file to the currently selected DUT port in the De-embedding columns. Remove Specified Adjustment button - Removes the SnP file from the currently selected DUT port in the De-embedding columns. Remove All in Current Tab button - Removes all SnP file selections from all DUT ports in the De-embedding columns.
Port Rotation/Extension Tab Specify Rotation - Enter the rotation in millimeters (mm). The equivalent time in picoseconds (ps) is also displayed.

Remove Specified Adjustment button - Removes the rotation adjustment from the currently selected DUT port in the Rotation columns. Remove All in Current Tab button - Removes all rotation adjustments from all DUT ports in the Rotation columns..
Port Reference Impedance Tab Single-Ended - Selects single-ended impedance. Diff/Comm - Selects differential and common mode impedances, which are de-coupled and can be changed independent of the single-ended impedance. Learn more. Specify the impedance in ohms - Enter real numbers between 0.0 ohms and 1000.0 ohms by 0.1 ohm increments using the Up/Down arrows. You can enter values to 11 places to the right of the decimal using the keyboard. Add Specified Adjustment button - Adds the current impedance adjustment to the currently selected DUT port in the Impedance columns. Remove Specified Adjustment button - Removes the impedance adjustment from the currently selected DUT port in the Impedance columns. Remove All in Current Tab button - Removes all impedance adjustments from all DUT ports in the Impedance columns..
