Functionality
Portable Part test
– Ability to act as a ba station fixed part, let the DUT
(handt) lock onto the applied dummy signal and es-
tablish a test mode connection with a DUT (handt),
农贸市场管理制度measuring the RF characteristics.
Fixed Part test
– Ability to act as a Handt part, locking onto a ba
station under test. With the Ba station test mode
enabled, the RF characteristics can be measured.
Using the Windows bad MMI, all transmitter and re-
ceiver measurements are shown in a parately win-
dow, with bars and graphs for identifying pass/fail lim-
its.
Operating frequency
Under test, all frequencies can be ud either as a
single channel or after a hopping scheme, simulating
a normal transmission environment.
RF level
The RF output level can be adjusted “on the fly” for
determining nsitivity of the device under test. The
RF Level output range is between -100 to -40 dBm.
Signaling modettled
The RTX 2201 2.4GHz Communication Tester is us-
ing loop back signaling, transmitting data to the DUT
and receive the looped data for RF analys.
This method makes it possible to measure veral RF
parameters transmitted by the Device under test, as
well as determine the DUT receiver nsitivity.
Modulation
Several different RF test signal modulation can be -
lected to obtain accurate measurements.
PSRB – Pudo random bit quence, similar to

SPSR - Static pudo random bit quence.
•
BS55 - Alternating zeroes and ones. Has the

smallest deviation.
BS33 - Alternating double zeroes and ones.
•
BS0F - Four times zeroes and four times ones
•
repeatable.
