UTS7000A-B85: 85 MHz Real-Time Bandwidth Upgrade

Overview

The UTS7000A-B85 provides 85 MHz of real-time analysis bandwidth—the sweet spot for engineers who need to look beyond single 40 MHz channels but don't require full 160 MHz Wi-Fi 6E coverage. At 85 MHz, you can capture a complete Wi-Fi 80 MHz channel with margin, monitor a 5G NR 80 MHz carrier with ACLR visibility into adjacent channels, observe three adjacent 20 MHz LTE carriers simultaneously, or analyze an FMCW radar chirp of up to 85 MHz instantaneous bandwidth—all with 100% POI guarantee and the high-speed 1 GSa/s ADC path.

The 85 MHz bandwidth is particularly compelling for multi-standard environments where you're not chasing the widest possible channel but need to see enough spectrum to understand what's happening around and between signals.

⚠ Factory-Installed Option: Bandwidth options require factory configuration during manufacturing. They cannot be field-upgraded. Specify UTS7000A-B85 when placing your order. Not compatible with -NB narrowband models.

What 85 MHz Gets You That 40 MHz Doesn't

Complete Wi-Fi 80 MHz Channel Capture: Wi-Fi 5 (802.11ac) and Wi-Fi 6 (802.11ax) support 80 MHz channels as a primary operating mode—it's the bandwidth that delivers the real-world throughput most users experience. At 40 MHz, you can only see half of an 80 MHz channel; at 85 MHz, you capture the entire channel plus 2.5 MHz of margin on each side. That margin matters because spectral mask compliance requires visibility beyond the channel edges. With the B40, you'd need multiple sweeps to characterize an 80 MHz channel. With the B85, it's one real-time capture—including any transient spectral regrowth, modulation anomalies, or spurious emissions that a swept measurement would miss.

5G NR 50–80 MHz Carriers with Adjacent Channel Visibility: A 50 MHz 5G NR carrier occupies roughly 48 MHz of occupied bandwidth. With 85 MHz of real-time coverage, you see the complete carrier plus significant adjacent channel territory—enough for meaningful ACLR screening in real-time. An 80 MHz NR carrier fills the 85 MHz window tightly but is still fully captured. This is the practical minimum bandwidth for engineers working with sub-6 GHz 5G NR carriers that routinely run at 50–80 MHz channel bandwidths in bands n77/n78.

Multi-Carrier LTE Monitoring: At 85 MHz, you can simultaneously observe up to four contiguous 20 MHz LTE carriers—the typical deployment for LTE-Advanced carrier aggregation. This enables real-time monitoring of inter-carrier interference, power balance between carriers, and timing alignment issues that don't appear when measuring carriers individually.

Wideband FMCW Radar Chirp Analysis: FMCW radars used in automotive (24 GHz), industrial level measurement, and surveillance applications employ chirp bandwidths from 40–200+ MHz. The 85 MHz real-time bandwidth enables complete capture of chirps up to 85 MHz—sufficient for many 24 GHz automotive radar systems and industrial radar sensors. You can analyze chirp linearity, spectral purity across the chirp bandwidth, and identify modulation-on-pulse anomalies in a single real-time acquisition.

Frequently Asked Questions

Why choose 85 MHz over 160 MHz?

Cost and application fit. If your work centers on Wi-Fi 80 MHz channels, 5G NR carriers up to 80 MHz, multi-carrier LTE, or radar chirps under 85 MHz, the B85 provides everything you need at a lower investment than the B160. The 160 MHz option is specifically justified when you need full Wi-Fi 6/6E 160 MHz channel capture or 5G carrier aggregation exceeding 85 MHz total bandwidth. Many engineering teams find that 85 MHz covers 90% of their real-time analysis needs.

Can I upgrade from 85 MHz to 160 or 255 MHz later?

No. Bandwidth options are factory-installed and cannot be upgraded in the field. If there's a reasonable chance you'll need wider bandwidth in the future—Wi-Fi 6E development, wideband 5G carrier aggregation, or ultra-wideband radar work—consider ordering the B160 or B255 from the start. The cost difference at time of purchase is substantially less than replacing the instrument.

Is the B85 compatible with narrowband -NB models?

No. The -NB narrowband variants have fixed 20 MHz bandwidth and a different internal architecture (100 MSa/s ADC) that cannot be upgraded. Bandwidth options are only available on standard upgradeable models (UTS7013A, UTS7026A, UTS7032A, UTS7040A).

Complete Wi-Fi 80 MHz and 5G NR carrier capture—the practical bandwidth for most wideband wireless development.
