Using the Script Menu MT8850A / MT8852A Bluetooth Test Set
Testing in Standard Script Mode
Individual tests can be tailored to suit requirements. The setup procedures and limits are
described on the following pages:
Output Power Test (Standard Mode)
The output power test performs power measurements on the EUT transmitted packets in
one of four ways.
With “Hopping On” mode set to “Defined” the MT8850A/MT8852A measures power only
when the link hops to one of the frequencies defined on the LOW, MEDIUM and HIGH set
up screen. Although the measurements are only made at the defined frequencies, it is still
a hopping link. The number of packets measured at each frequency is set by the user in
the “Number of packets” field. This is the test method described in the Bluetooth RF Test
Specification.
With “Hopping On” mode set to “All” the MT8850A/MT8852A measures the power at every
one of the 79 frequencies in the Bluetooth channel structure. The number of packets
measured at each frequency is set by the user in the “Number of packets” field.
With “Hopping On” mode set to “Any” the MT8850A/MT8852A measures the power at the
next frequency that the link hops to after the previous power measurement has been
completed. The total number of packets measured is set by the user in the “Number of
packets” field. This is typically the shortest of the three options as there is no requirement
to measure a large number of packets at specified frequencies.
The MT8850A/MT8852A can perform the test using either loopback test controls or TX
test controls. The default form for this test is to use loopback. The following test
description is described using the default test control.
The MT8850A/MT8852A transmits a pseudo random data payload (PRBS 9) of the
longest supported type (DH5, DH3 or DH1) or the selected packet type, to the EUT. The
EUT loops back the data at its maximum output power and the MT8850A/MT8852A
measures the received power. This test is performed while hopping, and the test is
repeated until the requested number of packets has been measured on each of the
selected frequencies. The LOW, MEDIUM and HIGH frequencies relate to the default
frequencies specified in the Bluetooth RF test specification. The MT8850A/MT8852A
allows all these frequencies to be changed from their default values.
1. Choose Output power from the Script menu.
2. Press the
key to select or deselect this test from the script routine.
If a test is selected, the box will be filled in. If not selected the box will be hollow.
