The Wireless Connectivity Test Set MT8862A supports an RF performance

measurement environment under realistic operation conditions (Network Mode).

Wireless Connectivity Test Set

MT8862A

Wide Connectivity Support

Connections are supported in the
IEEE802.11a/b/g/n/ac/ax*12x2MIMO AP
and STA modes. Additionally,
supporting securities, WEP, WPA­Personal and WPA2-Personal, makes
measuring various devices connect in

the Network Mode.

Built-in IP Data Ports

Ethernet ports for IP data are built-in and
IP continuity tests, such as ping between
the external PC client and DUT can be
performed under the same fixed­parameter conditions as at measurement.
Tx measurements are also supported
during IP data communication*2.

Intuitive GUI

Setup and measurement use a browser

GUI with access to Web servers from the

PC controller using a Web browser.
Control software installation and firmware
matching are unnecessary, and there is no
dependence on the PC controller OS.

Quality Assurance of Diverse and Complex Devices

*1: 11ax supports SISO and HESU(Single user) and HETB(Multi user for STA).

*2: 11as doesn’t support IP data communication.

Advantages of RF Measurement in Network Mode

The MT8862A Network Mode supports configuration of an RF measurement
environment without test firmware, chipset control, and hardware modification.

No Test Firmware

Firmware used by commercial products
can be tested and RF measurements can
be made without needing test firmware.

RF control faults which can’t be found

with test firmware can be analyzed.

No Hardware Modification

Since no interface is required for chipset
control, RF tests can be run without
modifying devices. This is ideal for RF
measurements of devices without
interfaces due to needs for
miniaturization, enhanced durability,

and cost control.

No Chipset Control

Chipset control required by test
firmware is unnecessary and
measurement is performed at the
required data rate using a unique data
rate control algorithm, helping unify the
measurement environment for different

parts used by chipsets.

11

MT8862A’s feature

Provides flexible RF tests from OTA to Conducted

High Speed measurement

MT8862A measures RF performance so quickly by
maintaining the connection when parameters are changed.

Data Rate Control Function

MT8862A can control data rate on the all standard in IEEE

802.11 a/b/g/n/acはIEEE802.11a/b/g/n/ac/ax. The other
WLAN tester cannot control data rate on 11ac/ax. Data

rate control is required to check the antenna performance
of DUR.

Wide Dynamic Range

MT8862A can demodulate low power and wide-band Wi­Fi signal by wide dynamic range. It is very important key
feature on the OTA test environment has a big air loss. All
Anritsu RF testers has this feature with priority.

MIMO measurement

MT8862A realizes 2x2 MIMO test on OTA. MT8862A is only
WLAN tester to measure RF performance on MIMO OTA
environment. The demand of MIMO OTA test is increasing
for User experience.

*it supports 11n/ac

12

• RF transmit tests are based on IEEE 802.11.

• The headers of packets received from the DUT are analyzed and RF measurements, such as

power, modulation accuracy, spectrum, etc., are performed to display results. Pass/Fail

evaluation of measurement results is performed based on the set reference values.

• At ACK measurement, the MT8862A sends an Test Packet to the DUT; at Data measurement, it
sends a ICMP Echo Request packet. Tx measurement is performed when either the ACK or ICMP
Echo Reply sent from the DUT is received.

• Packets sent using the IP data TRx ports can also be measured.

DUT Tx Test

13

DUT Rx Test

• RF receiver tests are based on IEEE 802.11.

• PER/FRR is measured by counting ACK frames sent from DUT in response to Test Packet.

• Configuring a measurement environment is easy by changing power automatically.

• The PER (Packet Error Rate) standard of the Receiver Blocking test in ETSI EN 300 328 V

2.1.1 has been added for broadband wireless devices operating in the 2.4 GHz ISM Band,
including WLAN. This test is done easily using the PER measurement function of the
MT8862A and a signal generator to generate the interference wave.

14

• The WLAN Measurement Software MX886200A captures WLAN frames sent to and
received from the DUT. Captured logs can be saved by the PC controller in pcap format for
analysis by software such as Wireshark. This eliminates the need for a separate packet
sniffer to capture WLAN frames and supports troubleshooting of WLAN frames in the RF
measurement environment.

Frame Capture for Troubleshooting DUT Connections

15

2x2MIMO Tx Test / Rx Test

• RF Performance of 2x2MIMO signals can be measured by 2 boxes in IEEE802.11n/ac.

• RF Tx test results will be showed by measurement of power and spectrum and analysis a

packet header received from DUT.

• RF Rx test results will be shown as PER and FRR measurement by counting ACK frames.

16

• Using the MT8862A, remote-control protocols, such as HiSLIP, VXI11,etc., for controlling
instruments using the general-purpose Raw-Socket connection method, can be selected
to match an existing remote-control environment.

• The same remote-control commands are used for the GUI running on the Web browser
and the GUI remote control command log can also be captured. Creation times are greatly
reduced by using remote-control command sequences.

• In addition, sample sequences are also provided for the SmartStudio Manager
MX847503A for the MT8862A.

• As WLAN applications diversify, WLAN devices and their usage environment are becoming
more complex, resulting in a growing need to quantify and verify that antenna
characteristics meet the design specifications by testing antenna characteristics, such as TX
power range, receiver sensitivity, etc.

• Anritsu supports an OTA measurement test environment with OTA chamber vendors for
measuring the reception power range and receiver sensitivity, such as TRP/TIS, to validate
RF performance in WLAN final-use environments.

Regulatory Test

Overview of ETSI Regulatory Test

Originally, the ETSI standard covered tests of transmitted power, spurious emission and etc., which were
measured with power meter and spectrum analyzer. However, "Receiver Blocking Test" has been added
in 2015, so a Signaling Unit or Companion Device is required as the opposing equipment. This test
item requires the calculation of the Packet Error Rate while communicating under the specific conditions
of Minimum Bandwidth and Minimum Data Rate, so the MT8862A Network Mode works effectively.

And, the EMC test, updated in September 2020, also uses PER as an indicator of performance,
increasing the need for Signaling measurement instruments.

Standard Number

RF testing for 2.4 GHz-Band : EN 300 328 V2.2.2
RF testing for 5 GHz-Band : EN 301 893 V2.1.1
EMC testing : EN 301 489-17 V3.2.4

Why MT8862A is better?

Source : EN 300 328 V2.2.2

UUT: Unit Under Test

• Using the Companion Device, it is difficult to
control to a given bandwidth and data rate.

• It's also difficult to measure PER without using
the Signaling Unit.

• It takes a lot of resources and time to build an
environment for communication state control
and communication quality monitoring using
devices other than the Signaling Unit.

20

IP Data Transfer

• The Ethernet port on the back panel of the MT8862A can be used for exchanging IP data
with an external server.

• IP connections between the client PC connected to the DUT and the external server
connected to the MT8862A can be checked using the ping function, etc.

• Connections can be checked and RF measurements can be made under fixed parameter
conditions, such as data rate.

• When it is necessary to access a specific server on the Internet at DUT connection, the
MT8862A can also be used for connection maintenance purposes.

• IP Data transfer supports IEEE 802.11a/b/g/n/ac.

MT8862A measures output power, specified on the radio low, of all frame including connection
attempt period by this function.

Normal mode

Tx Power mode

RF measurement starts after call connection established, with Single/Continuous
buttons. This mode complies with IEEE procedure.

RF measurement starts from before connection established at all frames.

Average Power (Average, Max, Min)
Peak Power (Average, Max, Min)
Crest Factor (Average, Max, Min)

All Frame Power measurement

Purpose: Measure Tx Power before connection is established. Because some devices output max power
during the period.

5 GHz Band DFS testing

WLAN, weather radar, marine radar, etc., use the same frequency bands in the 5.3 GHz
(Ch52-Ch64[W53/U-NII-2A]) and 5.6 GHz bands (Ch100-Ch144[W56/U-NII-2C]), so the
DFS (Dynamic Frequency Selection) technology is used to prevent signal interference
when these signals are detected.

Combining the Vector Signal Generator MG3710E with the waveform pattern product
supports the DFS test defined by TELEC, ETSI, and FCC for 5 GHz band WLAN devices.
