Overview

The UTS7000A-B255 bandwidth upgrade option provides maximum real-time analysis capability with industry-leading 255 MHz instantaneous bandwidth, enabling complete capture of the widest 5G mmWave carriers, ultra-wideband satellite communications, extensive multi-carrier aggregation, and the most demanding wideband radar systems. This factory-installed upgrade delivers more than 12× the standard 20 MHz bandwidth with 100% Probability of Intercept at 4.5 μs—guaranteed signal capture across the complete 255 MHz span. Engineers developing cutting-edge wireless technologies benefit from the widest real-time coverage in the Interceptor-Series, ensuring even the most complex ultra-wideband signals, rapid transient events, and extensive multi-carrier scenarios are captured with absolute certainty.

Maximum Bandwidth, Guaranteed Capture, Ultimate Capability

The 255 MHz option represents the flagship real-time analysis capability for UTS7000A Interceptor-Series analyzers. When standard 20 MHz, 40 MHz, or even 85/160 MHz bandwidths cannot accommodate signal requirements, the B255 upgrade provides the comprehensive coverage that ultra-wideband applications demand. This is the widest real-time bandwidth available in the Interceptor-Series, delivering complete investment protection and maximum future-proofing for evolving wireless technologies.

5G New Radio millimeter-wave bands support channel bandwidths up to 100 MHz for maximum data throughput and network capacity. Band n257 (26.5-29.5 GHz), n258 (24.25-27.5 GHz), and n260 (37-40 GHz) enable multi-gigabit wireless connectivity using these ultra-wide channels with high-order modulation (up to 256-QAM). Testing 100 MHz 5G carriers requires real-time analysis capability that captures the entire channel bandwidth—the UTS7000A-B255 option provides 255 MHz coverage, enabling complete 100 MHz carrier capture with substantial margin for guard bands and adjacent channel analysis.

Complete 5G mmWave Characterization:

• 100 MHz carrier capture with 77.5 MHz margin for ACLR measurement
• EVM analysis across entire ultra-wide carrier bandwidth
• Spectral mask verification with complete adjacent channel visibility
• TDD uplink/downlink switching transient capture with 100% POI
• Beamforming event analysis across full channel bandwidth

5G networks combine multiple component carriers through carrier aggregation to achieve maximum throughput and network capacity. At mmWave frequencies, networks may aggregate multiple 50-100 MHz carriers for total bandwidths exceeding 200 MHz. The 255 MHz real-time bandwidth enables simultaneous capture of extensive carrier aggregation scenarios—monitoring two 100 MHz carriers, four 50 MHz carriers, or mixed-bandwidth combinations totaling up to 255 MHz. All carriers are captured with 100% POI across the full span, enabling comprehensive multi-carrier power distribution, timing alignment, and modulation quality analysis impossible with narrower bandwidth analyzers.

High-resolution FMCW radar systems employ chirp bandwidths from 200 MHz to several GHz at the final radar frequency. At intermediate frequencies or in subsystem analysis, these chirps may appear at bandwidths within the UTS7000A-B255 capability. The 255 MHz real-time bandwidth enables complete capture of ultra-wideband chirps for detailed linearity analysis, verification of chirp rise/fall characteristics, and identification of spectral impurities that could degrade radar resolution. The 4.5 μs POI ensures that even rapidly repeating chirps are captured accurately regardless of chirp repetition rate.

Commercial satellite transponders range from 36 MHz to 72 MHz bandwidth, with some systems using wider allocations or hosting multiple carriers within broader frequency blocks. The 255 MHz real-time capability enables monitoring of multiple transponders simultaneously, capturing entire satellite frequency allocations for interference analysis, carrier identification, and spectrum occupancy assessment. This capability is particularly valuable for satellite operations centers monitoring multiple transponders, identifying cross-transponder interference, and validating frequency coordination across complex satellite networks.
