Contains the raw 3D imaging data.
Only if you have selected the data package "Stat Pi Data + Vol-
ume".
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
(
results.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 7 Embedded 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.
If verification fails, calibrate the R&S
QAR. If calibration still results in a failed verifica-
tion, check the hardware for defects.
