Overview

1 Overview

When doing measurements according to ETSI EN 300 328 V2.1.1 it is mandatory to do

a "Receiver Blocking" test. For tests according to ETSI EN 301 893 V2.1.1 an

"Adaptivity" test is needed. This application note describes an example of how to do

such tests.

The "Receiver Blocking" test requires a "Performance Criteria" for the DUT. The

minimum "Performance Criteria" is a PER <= 10% according to the standard. But the

manufacturer may also declare alternative "Performance Criteria".

In this application note we use PER as "Performance Criteria" but please be aware that this is

highly DUT dependent - DUTs may require different criteria.

The "Adaptivity" test for ETSI EN 301 893 V2.1.1 requires a "full buffer condition". In

this example we use a Wi-Fi adapter as companion device to reach this condition.

5 Receiver Blocking

The measurement example below will describe how to do a "Receiver Blocking" test

for a Bluetooth device and for a Wi-Fi device according to ETSI EN 300 328 V2.1.1.

In both cases we are using PER as "Performance Criteria" for the DUT. But the

manufacturer may also declare alternative "Performance Criteria".

Please be aware that the tests described below are only an example. The tests are heavily DUT

dependent. Please pay attention to the manufacturer's instructions for any specific device you

want to test.

5.1 Bluetooth 2.4 GHz

This example describes how to do a receiver blocking test for the Bluetooth section of

a Nokia C5 cell phone. This device has Bluetooth 2.1 + EDR (Enhanced Data Rate).

We do the test inside a RF shielded box. If the DUT has a cable connection you can

also perform this test using a cable connection.

The test will be done in a fixture using a RF shielded box TS7124M and a TS-F24-V1

Vivaldi antenna.

5.1.1 Preparations

Please add "CMW500-BT" to the device list of WMS32. Enter connection information

and try to connect to your CMW270.

5.1.2 Create DUT Configuration

Create a new DUT configuration. As standard please select EN 300 328 V2.1.1.

the cable about 1dB => 40dB. In tab "Signaling" check "Hopping", enter -40dBm for

"TX Level" and -13dBm for "Expected Nominal Power". To find those values connect

CMW manually to the device (please see 7) and look for "Tx Level" and "Exp. Nom.

6 Adaptivity 5GHz Conducted

The measurement example below will describe how to do a conducted "Adaptivity" test

for a Wi-Fi device according to ETSI EN 301 893 V2.1.1.

Please be aware that the test described below is only an example. The test is heavily DUT

dependent. Please pay attention to the manufacturer's instructions for any specific device you

want to test.

The test for 2.4 GHz according to ETSI EN 300 328 V2.1.1 will work accordingly.

6.1.1 Preparations

For the Adaptivity test we are using a Wi-Fi stick with RP-SMA connector. This

connector is necessary for connecting the Wi-Fi stick to the companion port.

In this example we are using a Wi-Fi stick from TP-Link: Archer T2UH AC 600

6.1.2 Create DUT information

Create a new DUT configuration. As standard please select EN 301 893 V2.1.1.

In tab "ETSI settings" choose "Master" for "DFS Operating Mode". The configuration

6.1.4 Test

For the test please connect DUT port 1 of 5GHz part to port 4 of OSP and connect the

Wi-Fi to the companion port ("COMP").


After the connection between DUT and Wi-Fi stick has been established we need to

create traffic between them. We use "IPerf" in UDP mode for creating traffic. You can

use any "IPerf" installation for doing so. In this example "JPerf" (i.e.

https://code.google.com/archive/p/xjperf/downloads) is used.

Please install it on a computer connected to the DUT and start it. Fill in details like IP-

address, port, "UDP" protocol and bandwidth and start it. Finally it should look like in

Figure 53.



32

Figure 53: JPerf DUT settings

For the Wi-Fi stick please install "JPerf" on a second computer, connect it to the stick

via USB, configure JPerf according to Figure 54 and start it.

Once you created traffic you may look into DUT and look for the workload, please see

Figure 55.

Now you can start and run the test. Results should be as shown in Figure 56.

7 Connection Test

If you want to test the connection between CMW and DUT you can directly switch to

the reduced attenuation path.

Please follow the following instructions:

- Exit WMS32 and restart the application

- Open Self Check by "Extras" -> "Self Check"

- Double click on OSP to open the Self Check dialog for the OSP

- Select "Patch Companion to DUT4" and press button "Switch". Please see Figure 57.

Now you have established a reduced attenuation path between the OSP ports "DUT4"

and "COMP".
