The contents depend on your selection.
–
If you have selected the data package "Stat Pi Data", the file
contains the raw 2D imaging data. This data package is necessary if you
want to restore the measurement results later on.
–
If you have selected the data package "Stat Pi Data + Vol-
ume", the file also contains the 3D imaging data.
This data package requires approx. 500
MB of disk space for each image.
It also takes a long time to save this data package, approx. 30
seconds for
each image.
Tip:
You can restore measurement results at any time with the keyboard shortcut
Ctrl-O or from the "File" menu.
Restoring measurement results requires at least the raw 2D imaging data
(
result_QARQT.mat
). The data package "Stat Pictures" only contains the
images (
.png)
and statistics (numerical results etc.) and is therefore not sufficient
to restore results.
Taking pictures with a webcam
You can connect a webcam to the R&S
QAR that takes a picture of the DUT during the
measurement. This picture is stored together with the measurement data.
The R&S
QAR supports all webcams that are recognized as an "Imaging Device" in
the Windows
10 device manager. Note that the webcam feature of the R&S
QAR
always uses the first imaging device in the list to take pictures.
1. Select "Options" > "Recording".
2. Select "Save Webcam Picture".
Using a barcode scanner
You can connect a barcode scanner to the R&S
QAR to scan the barcode of a DUT
and use this as a reference that the DUT with a certain barcode has passed or failed
the test. The barcode is displayed in the user interface and is stored together with the
other measurement data.
The R&S
QAR supports the barcode scanner Honeywell Xenon 1900 by Honeywell
International Inc.
1. Select "Options" > "Recording".
2. Select "Use Barcode Scanner".
3. Select the (serial) port the barcode scanner is connected to from the dropdown
menu.

Verification
The R&S
QAR provides a verification procedure to validate the quality of the measure-
ments. Verification consists of a series of measurements with standardized DUTs
which are located at a fix distance from the R&S
QAR.
