R&S TA-TRS Overview
1 R&S TA-TRS Overview
R&S TA-TRS is a sequencer software tool that is used together with R&S BTC and
certain accessories to provide the user with test automation and test reporting capabilities. The software features a user-friendly interface and unique test configurations such
as compensation loss, multiple interfering signals and smart learning of DUT control
via infrared remote control.
Used together with the R&S Broadcast Instruments, it offers users easy execution and
management of test cases for product validation and production testing. Offers an
automated test platform to perform RF and interoperability tests. In these tests, you
verify your product in accordance to the ETSI standards.
The test suite is designed to optimize the testing time. The versatile configuration
allows you to tailor the tests according to your different requirements, for example you
can perform the tests only on a subset of test signals.
The key facts are as followed:
●
Supports all test cases for EN 303340, EN 303345 and EN 303372-2
●
Automated detection of picture failure point for video and audio
●
Optional camera solution for automated error detection on TV screens
●
Intuitive state-of-the-art GUI with signal path loss compensation
●
Reproducible and consistent test results
●
Future-proof solution since more standards can easily be integrated into the software solution

There are different test setups for different standard manually and automatically. All the
different test setups describes in following sub section.
The following setups are for EN303340/EN303372 automated testing for DUT without
screen like set-top box. Based on K8 (Baseband routing) option, additional coupler or
combiner is required. Legacy instrument option allows using SFU and SFE as an interferer signal with 1 path BTC.

There is a limitation when you use K8 option. Dynamic range between two signals like
wanted signal and unwanted signal is 56 dB. So, result is more than 56 dB, report
shows >56 dB.
The above setup consists of the following:
●
Computer: TA-TRS installed connected to BTC via LAN or GPIB
●
BTC: Proper options that mentioned in Chapter 2, "Prerequisites", on page 6
●
Matching pad: DUT input is 75 ohm and BTC output is 50 ohm
●
RedRat/RedRatX: DUT control for channel searching using IR (infrared) signal,
which connected to computer. You need to run learning process to create control
sequence before testing
●
Coupler or Combiner: without K8 option, it is required to combine two signals
●
Cables: RF cables, HDMI cable, LAN cables
4.2 EN303340 & EN303372 Automated Test Setup with Camera
Please do not use router to connect camera and BTC with PC. It drops transmission
data rate from camera and cause missing frame.
The following setup is for EN303340/EN303372 automated testing with AVB Camera
for DUT with screen like TV.

4.3 EN303345 Automated Test Setup
The following setups are for EN303345 automated testing for Radio receiver DUT like
analog or digital radio. Based on K8 (Baseband routing) option, additional coupler or

To define the quality parameters used for A/V analysis to reliably assess video
quality and detect any deviation from a reference signal. PSNR and SSIM are the
objective metric and most commonly used for quality measurements of compressed images.
– "SSIM"
Define structural similarity index to be used for the threshold limit setting for
picture failure point measurement. The value range is 0 dB to 1 dB and value of
1 is achieved if there is two similar sets of data. Recommended is 0.97
– "PSNR"
Define peak signal to noise ratio to be used for the threshold limit setting for
picture failure point measurement. The value range is 0 dB to 100 dB. The
higher the value, the better the quality. Recommended are 35 dB.
– "Measurement Duration"
Define measurement period. The value range is 20 ms to 999 ms. Recommended is 200 ms.
●
Reference Video Quality
Define the reference video quality for Auto test. Auto test is required to make reference video file. After making it, TA-TRS will check whether the quality is good
enough. If the result is lower than threshold, the test stops and issues a warning
message

Matching pad is necessary to match the impedance between BTC and DUT. However, power sensor cannot compensate the matching pad because of different
impedance. It is added manually into measured setup loss.
● Constant: Constant value applies to all frequency range. Default is 5.72 dB.

Test Preparation
Learning DUT IR Commands
To allow full automation, TA-TRS is using the RedRat 3-II or RedRat-X IR remote control to establish an intelligent learning system. Firstly, you teach the RedRat 3-II or
RedRat-X the IR signals of the original DUT remote control. Then you construct the
sequences to remotely control the DUT using the RedRat 3-II or RedRat-X.
The RedRat 3-II or RedRat-X IR remote control consists of a hardware and software
component. The hardware component sends and receives IR signals. The software
component controls the hardware component and is integrated into the TA-TRS.
To display the "Infrared Remote Control" dialog and connect the RedRat 3-II or
RedRat-X.
Open the "Remote Control DUT dialog" and click "Make New Sequence".

check whether IR signal operates correctly.
Construct the sequences to remotely control the DUT after learning all buttons.
It is used for channel or frequency scan for DUT during the test. Before constructing
the sequence, BTC needs to generate proper signal to DUT to work with DUT.
1. Under "Action", select "Step 3: Learn Sequences" to create a new sequence file.
2. Under "Mode", select "Channel/Frequency switching" which is only selection at this
moment.
3. Under "Type of scanning", select one of four options.
Figure 6-25: Type of scanning menu
● "Full Scan - no channel/Frequency"
It is known as auto scan without any additional frequency input during scan
procedure. This mode can cover most of applications.
● " Scan entering Frequency [MHz]"
It is known as manual scan with frequency(MHz) input during scan procedure.
This frequency keeps changing during the actual test. It needs to give timing
information to generate proper frequency (MHz). "Insert Freq.[MHz]" button
works for it. Put "Insert Freq.[MHz]" into sequence when manual frequency is
required during scan procedure.
