UTS7000A-B85 85 MHz Real-Time Analysis Bandwidth License for UTS7000A
Overview
The UTS7000A-B85 is the software-license option that expands the UTS7000A series real-time analysis bandwidth from the 40 MHz baseline to 85 MHz. Every US-market UTS7000A chassis (UTS7013A, UTS7026A, UTS7032A, and UTS7040A) ships pre-calibrated to the 40 MHz baseline. The B85 license unlocks the wider bandwidth path on the same chassis — no return-to-factory, no hardware change.
The expansion applies to both real-time spectrum analysis and I/Q capture, and lifts the maximum sampling rate to 1 GSa/s. The license is purchased against the chassis serial number, installed via the chassis Option Install menu, and is permanent for the life of the instrument.
Key Features
- 85 MHz real-time analysis bandwidth — Expands RTSA and I/Q analysis from the 40 MHz baseline.
- 1 GSa/s sampling on the wide-band IF path — Up from 100 MSa/s on the 20 MHz baseline path.
- Step in the upgrade path — The B85 path can later be replaced by the wider UTS7000A-B160 (160 MHz) or UTS7000A-B255 (255 MHz) licenses on the same chassis.
- Lifetime License Activation — activate once, owned for the life of the instrument. No subscriptions, no renewals, no maintenance fees.
What Changes With B85 Installed
The following specifications shift from the 40 MHz baseline to the 85 MHz path when the B85 license is active. Values are taken directly from the UTS7000A Series datasheet.
| Specification | 40 MHz Baseline | With B85 Installed |
|---|---|---|
| I/Q analysis frequency-sweep width | 10 Hz to 40 MHz | 10 Hz to 85 MHz |
| RTSA analysis bandwidth | 5 kHz to 40 MHz | 5 kHz to 85 MHz |
| Max sampling rate | 100 MSa/s (20 MHz baseline path); 1 GSa/s (40 MHz path) | 1 GSa/s |
| I/Q data rate | IFBW × 1.25 (20 MHz path); IFBW × 1.2 (40 MHz path) | IFBW × 1.2 |
| Min. signal duration for 100% POI at RBW6 (Kaiser, 85 MHz span) | — | 3.24 μs |
| Min. RBW at 85 MHz span (Kaiser window) | — | 294.0028 kHz |
| Max. RBW at 85 MHz span (Kaiser window) | — | 9.4669 MHz |
| ADC resolution | 14 bits | 14 bits (unchanged) |
When You Need This Option
The B85 license is appropriate when measurements need real-time capture or wider I/Q analysis beyond the 40 MHz baseline. Typical workflows:
- Wideband modulated signal capture — Signals with instantaneous bandwidth between 40 and 85 MHz that exceed the baseline capture window.
- 5G NR component carriers — Carriers with 50, 60, 70, or 80 MHz system bandwidth in FR1, captured in a single record without segmented acquisition.
- Frequency-hopping and pulsed signals — Wider real-time bandwidth raises the probability of intercept for short-duration events that fall outside the baseline 40 MHz window.
- Wideband I/Q records for offline analysis — 8,000,000 IQ sample pairs at 1 GSa/s sample rate for vector-signal-analysis post-processing.
For instantaneous bandwidth requirements beyond 85 MHz, the UTS7000A-B160 (160 MHz) and UTS7000A-B255 (255 MHz) licenses extend the same path further; both install on the same 40 MHz-baseline chassis the B85 targets.
Compatibility
The UTS7000A-B85 is a software license installed on a UTS7000A chassis. Compatibility is determined by chassis variant:
| Chassis variant | B85 license install |
|---|---|
| UTS7013A (40 MHz baseline) | Supported |
| UTS7026A (40 MHz baseline) | Supported |
| UTS7032A (40 MHz baseline) | Supported |
| UTS7040A (40 MHz baseline) | Supported |
| UTS7000A–NB narrow-band variants (20 MHz fixed) | Not supported — the narrow-band chassis hardware does not accept B-series licenses. |
Frequently Asked Questions
Is the UTS7000A-B85 a software license or a hardware option?
It is a software license. Every US-market UTS7000A chassis ships pre-calibrated to the 40 MHz baseline at the factory; the B85 expansion is unlocked field-side on the existing chassis via a license file. No return-to-factory and no hardware change are required.
How is the license installed?
The license is purchased against the chassis serial number, registered on the UNI-T website to obtain the license file, and installed via the chassis Option Install menu using a USB storage device. Refer to the chassis User Manual for the full step-by-step procedure.
Is the license permanent, or does it require renewal?
The license is permanent — a one-time purchase that remains active for the life of the instrument. There are no subscription fees, no annual renewals, and no expiration date.
Can the B85 license be installed on a UTS7000A–NB chassis?
No. The narrow-band (–NB) chassis variants are fixed at 20 MHz real-time bandwidth with no upgrade path. B-series licenses install only on the 40 MHz-baseline wide-band variants (UTS7013A, UTS7026A, UTS7032A, UTS7040A).
Can I upgrade later from B85 to B160 or B255?
Yes. The B85, B160, and B255 licenses are sold as separate purchases against the same chassis. Customers who later need wider bandwidth purchase the higher-tier license against the same chassis serial number. Consult UNI-T sales for license-upgrade specifics on a chassis that already has B85 installed.
