UTS7000A-B255 255 MHz Real-Time Analysis Bandwidth License for UTS7000A
Overview
The UTS7000A-B255 is the software-license option that expands the UTS7000A series real-time analysis bandwidth from the 40 MHz baseline to 255 MHz β the widest real-time analysis bandwidth available on the UTS7000A platform. Every US-market UTS7000A chassis (UTS7013A, UTS7026A, UTS7032A, and UTS7040A) ships pre-calibrated to the 40 MHz baseline. The B255 license unlocks the widest bandwidth path on the same chassis β 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
- 255 MHz real-time analysis bandwidth β Expands RTSA and I/Q analysis from the 40 MHz baseline to the widest span available on the UTS7000A platform.
- 1 GSa/s sampling on the wide-band IF path β Up from 100 MSa/s on the 20 MHz baseline path.
- Top of the upgrade path β The B255 license supersedes the UTS7000A-B85 (85 MHz) and UTS7000A-B160 (160 MHz) options on the same chassis.
- Lifetime License Activation β activate once, owned for the life of the instrument. No subscriptions, no renewals, no maintenance fees.
What Changes With B255 Installed
The following specifications shift from the 40 MHz baseline to the 255 MHz path when the B255 license is active. Values are taken directly from the UTS7000A Series datasheet.
| Specification | 40 MHz Baseline | With B255 Installed |
|---|---|---|
| I/Q analysis frequency-sweep width | 10 Hz to 40 MHz | 10 Hz to 255 MHz |
| RTSA analysis bandwidth | 5 kHz to 40 MHz | 5 kHz to 255 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 Γ 1.25 (20 MHz path); IFBW Γ 1.2 (40 MHz path) | IFBW Γ 1.2 |
| Min. signal duration for 100% POI at RBW6 (Kaiser, 255 MHz span) | β | 3.21 ΞΌs |
| Min. RBW at 255 MHz span (Kaiser window) | β | 882.0084 kHz |
| Max. RBW at 255 MHz span (Kaiser window) | β | 28.4007 MHz |
| ADC resolution | 14 bits | 14 bits (unchanged) |
When You Need This Option
The B255 license is appropriate when measurements need the widest real-time capture and I/Q analysis available on the UTS7000A platform. Typical workflows:
- Wideband modulated signal capture β Signals with instantaneous bandwidth between 160 and 255 MHz that exceed the B160 capture window.
- 5G NR contiguous component carriers in FR1 β Multi-carrier aggregations up to 200 MHz contiguous, captured in a single record without segmented acquisition.
- Wideband radar and EW signal analysis β Frequency-agile, pulsed, or chirped signals with instantaneous bandwidths up to 255 MHz.
- Frequency-hopping signals with broad hop range β Wider real-time bandwidth raises the probability of intercept for short-duration events that fall outside narrower spans.
- Wideband I/Q records for offline analysis β 8,000,000 IQ sample pairs at 1 GSa/s sample rate for vector-signal-analysis post-processing.
The B255 is the top tier of the B-series real-time bandwidth options. Chassis already running UTS7000A-B85 or UTS7000A-B160 licenses can be upgraded to B255 via a separate license purchase against the same chassis serial number.
Compatibility
The UTS7000A-B255 is a software license installed on a UTS7000A chassis. Compatibility is determined by chassis variant:
| Chassis variant | B255 license install |
|---|---|
| UTS7013A (40 MHz baseline) | Supported |
| UTS7026A (40 MHz baseline) | Supported |
| UTS7032A (40 MHz baseline) | Supported |
| UTS7040A (40 MHz baseline) | Supported |
| UTS7000AβNB narrow-band variants (20 MHz fixed) | Not supported β the narrow-band chassis hardware does not accept B-series licenses. |
Frequently Asked Questions
Is the UTS7000A-B255 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 B255 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 β 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 B255 license be installed on a UTS7000AβNB chassis?
No. The narrow-band (βNB) 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 or B160 to 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 B255 license against the same chassis serial number. Consult UNI-T sales for license-upgrade specifics on a chassis that already has B85 or B160 installed.
