DESCRIPTION

The VIAVI 8800SX Digital Radio Test Set is an advanced communications service monitor engineered for installation, maintenance, troubleshooting, alignment, and performance verification of modern analog and digital radio systems. Designed for both bench and field environments, the 8800SX combines laboratory-grade measurement capability with portable field deployment flexibility.

The platform supports a wide range of land mobile radio technologies including:

AM
FM
P25
P25 Phase 2
DMR (MOTOTRBO™)
NXDN™
TETRA
dPMR
Positive Train Control (PTC)

making it suitable for public safety, utilities, transportation, industrial, military support, and commercial radio maintenance operations.

The 8800SX incorporates comprehensive radio test capability including:

RF signal generation
Receiver testing
Power measurement
Modulation analysis
Frequency error measurement
Spectrum analysis
Channel analysis
Audio analysis
Automated alignment

allowing technicians to perform complete transmitter and receiver verification from a single platform.

A key advantage of the 8800SX is its extensive Auto-Test and Alignment capability, supporting automated service procedures for a wide range of radio manufacturers. Automated workflows reduce service time while improving repeatability and maintenance consistency across large radio fleets.

The integrated tracking generator provides infrastructure testing functions including:

VSWR measurements
Return loss analysis
Distance-to-Fault (DTF)
Duplexer tuning
Antenna testing
Feedline diagnostics

allowing a single instrument to support both radio and RF infrastructure maintenance activities.

The large 12-inch colour touchscreen, Fast Stack interface, user presets, frequency lists, and rapid measurement architecture are designed to improve technician productivity during both field and workshop operations. The internal battery provides portable operation without sacrificing performance.
