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".

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, validate the verification setup. If verification fails several times in a
row, despite a valid setup, contact Rohde
&
Schwarz customer support to calibrate the
R&S
QAR and check the hardware.
Required equipment
All required equipment is included in the delivery of the R&S

Mounting frame for verification objects
Installing the mounting frame for the verification objects
The verification set includes a mounting frame that holds the verifications objects. For
verification, you have to place the mounting frame in front of the R&S
QAR at a defined
location. If the distances deviate from the ones mentioned here, verification is invalid.
●
The distance between the R&S
QAR and the front edge of the mounting frame is
65
cm.
