UTS7000A-B160 160 MHz Real-Time Analysis Bandwidth License for UTS7000A
Overview
The UTS7000A-B160 is the software-license option that expands the UTS7000A series real-time analysis bandwidth from the 40 MHz baseline to 160 MHz. Every US-market UTS7000A chassis (UTS7013A, UTS7026A, UTS7032A, and UTS7040A) ships pre-calibrated to the 40 MHz baseline. The B160 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
- 160 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 B160 path sits between the UTS7000A-B85 (85 MHz) and 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 B160 Installed
The following specifications shift from the 40 MHz baseline to the 160 MHz path when the B160 license is active. Values are taken directly from the UTS7000A Series datasheet.
| Specification | 40 MHz Baseline | With B160 Installed |
|---|---|---|
| I/Q analysis frequency-sweep width | 10 Hz to 40 MHz | 10 Hz to 160 MHz |
| RTSA analysis bandwidth | 5 kHz to 40 MHz | 5 kHz to 160 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, 160 MHz span) | — | 6.41 μs |
| Min. RBW at 160 MHz span (Kaiser window) | — | 553.0802 kHz |
| Max. RBW at 160 MHz span (Kaiser window) | — | 17.7504 MHz |
| ADC resolution | 14 bits | 14 bits (unchanged) |
The minimum signal duration for 100% POI at the 160 MHz span (6.41 μs) is the longest in the B-option family — wider real-time spans capture less signal energy per unit time at the same RBW selection, so brief events that resolve cleanly on the 85 MHz or 255 MHz paths may require longer dwell at 160 MHz. Verify against the application before sizing acquisition.
When You Need This Option
The B160 license is appropriate when measurements need real-time capture or wider I/Q analysis beyond the 85 MHz option but do not require the full 255 MHz span. Typical workflows:
- Wideband modulated signal capture — Signals with instantaneous bandwidth between 85 and 160 MHz that exceed the B85 capture window.
- 5G NR component carriers up to 100 MHz — Single-carrier NR FR1 captures at 100 MHz system bandwidth, with margin for adjacent-channel leakage measurements within the same record.
- Frequency-hopping and pulsed signals — Wider real-time bandwidth raises the probability of intercept for short-duration events that fall outside the 85 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 160 MHz, the UTS7000A-B255 (255 MHz) license extends the same path further; it installs on the same 40 MHz-baseline chassis the B160 targets.
Compatibility
The UTS7000A-B160 is a software license installed on a UTS7000A chassis. Compatibility is determined by chassis variant:
| Chassis variant | B160 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-B160 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 B160 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 B160 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).
Why is the minimum signal duration at 160 MHz longer than at 85 MHz or 255 MHz?
The minimum-signal-duration values in the datasheet are RBW-dependent. At the 160 MHz span on the Kaiser window with the RBW6 selection, the duration is 6.41 μs — longer than the 85 MHz span (3.24 μs) or the 255 MHz span (3.21 μs) at the same RBW selection. This is a property of how the FFT bin width scales against span width at this specific RBW choice; selecting a different RBW from the available six options will change the duration. Verify against the application before sizing acquisition.
Can I upgrade later from 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 higher-tier license against the same chassis serial number. Consult UNI-T sales for license-upgrade specifics on a chassis that already has B160 installed.
