• Frequency error
• FSK error
• Symbol deviation
• TX BER
• Symbol clock error
The system supports both 4800 and 9600 baud systems. The
3920B can also analyze the modulation as an eye diagram, symbol
distribution plot and a symbol constellation plot. A power over time
graph can be used to diagnose power-related issues.
Example of NXDN Tiles
The 3920B NXDN Option supports receiver testing with a variety of
signal generation patterns.
• STD 1031 (1031 Hz pattern)
• STD CAL (1031 Hz pattern with 5% BER)
• STD 511 (PN9 bit sequence)
• STD INTFR (PN15 bit sequence)
ARiB STD T98 (390XOPT460)
The option provides testing for mobile stations that conform to the
ARIB T98 standard. This testing is similar to dPMR and NXDN.
TETRA

signal T1
• Transmit parameter measurements including power, frequency
error, EVM and burst timing
• TETRA RF power meter and burst power analysis up to 125 W
• Modulation analysis with I/Q constellation and trajectory display
• Receiver Bit Error Rate (BER) and Message Error Rate (MER)
measurements
• Pass/Fail indication using color coded meters

• Option for testing Direct Mode Operation (DMO)
Example of TETRA MS Tiles
For TETRA applications, the 3920B is the successor to the Aeroflex
2968 TETRA Radio Test Set, the established industry standard for
TETRA R&D, manufacturing, application development and service
operations. Building upon the experience gained over many years of
TETRA test, the 3920B with the TETRA options provides the world’s
best solution for testing TETRA radios. TETRA system options
provide signaling and physical layer measurement requirements
for testing TETRA radio equipment. Measurements are made in
accordance with ETSI EN 300 394-1 for on channel transmitter
and receiver parameters. Signaling functions support TIP (Tetra
Interoperability Profile) compliant TETRA radios, thus ensur-
ing optimum compatibility with TETRA equipment from various
suppliers. Whatever the device under test, the TETRA system
options have the flexibility to measure the various burst types
specified by the TETRA standard including normal bursts, control
bursts and synchronization bursts. The 3920B offers high speed
measurement capabilities to expedite production testing. As a
direct benefit of high power signal processing capacity, TETRA
measurements are performed nearly nine times faster than its
predecessor.
