UTS7013A-NB 13GHz Interceptor-Series Signal Analyzer; 20MHz RSA

UNI-T UTS7013A-NB 13.6 GHz Narrow-Band Signal Analyzer Overview The UNI-T UTS7013A-NB is a 13.6 GHz narrow-band signal analyzer for commercial wireless, IoT, EMI pre-compliance, and R&D characterization work where wideband real-time capture is not required. It covers 2 Hz – 13.6 GHz on a single chassis, with −167 dBm/Hz displayed average noise level (DANL with preamplifier engaged) and 100,001 sweep points across the span. The UTS7013A-NB is the narrow-band configuration of the UTS7000A line, with 20 MHz real-time analysis bandwidth fixed at the factory. The full ecosystem of measurement options — 5G NR demodulation, vector signal analysis, I/Q capture, EMI pre-compliance, phase noise, advanced power measurements, analog demodulation, and LTE FDD/TDD — expands the same hardware platform to specialized workflows without buying a second instrument. Choosing Your Model — UTS7000A Series The UTS7000A name spans eight models on one signal-analyzer platform. The series splits into two configurations: a wide-band configuration (40 MHz baseline real-time bandwidth, software-expandable to 255 MHz) and a narrow-band –NB configuration (20 MHz fixed real-time bandwidth, no upgrade path). Sampling, sweep points, phase noise, DANL, display, interface, and option compatibility are identical across all eight models. Choose the maximum frequency your work requires, then choose the bandwidth configuration.

Choose the wide-band configuration when wideband real-time capture matters: multi-carrier signals, 5G NR FR2 component carriers, wideband modulated payloads, or transient capture across spans up to 255 MHz. Key Features Frequency range 2 Hz to 13.6 GHz, single chassis, no band switching −167 dBm/Hz displayed average noise level with the UTS7000A-P13 preamplifier engaged Phase noise <−110 dBc/Hz Real-time spectrum analysis included — 20 MHz fixed bandwidth, narrow-band configuration 100,001 sweep points, six traces, 1 Hz to 10 MHz RBW range 11.6-inch TFT-LCD touchscreen with full front-panel keyboard USB 3.0, USB 2.0, LAN, HDMI, 10 MHz reference In/Out, dual trigger inputs Nine software-licensed measurement options on one platform — 5G NR, VSA, I/Q, EMI, PNM, AMA, AMK, FDD-LTE, TDD-LTE UNI-T UTS7013A-NB Details Real-time bandwidth display — modulated signal capture in a single record Fixed 20 MHz Real-Time Bandwidth — Narrow-Band Configuration Real-time spectrum analysis is part of the base instrument. The UTS7013A-NB is the narrow-band configuration of this chassis: 20 MHz of real-time analysis bandwidth is fixed at the factory and is not upgradable. Within that 20 MHz capture window the instrument achieves 100% frequency-domain signal capture in under 3.21 µs, so transient and intermittent signals that a swept analyzer would miss are captured into the trace. The instrument supports density spectrum, spectrogram (waterfall), and Power-vs-Time displays simultaneously, plus a Frequency Mask Template (FMT) trigger for capture on signal arrival, departure, or shape change. The narrow-band configuration suits work where the signal of interest fits within a 20 MHz capture window — single-carrier monitoring, narrow-channel comms test, slow-hopping signal capture, and EMI pre-compliance work on conducted-emissions spans. For wideband real-time analysis up to 255 MHz, the wide-band UTS7013A configuration is the upgrade path. ×Real-time bandwidth display — modulated signal capture in a single record Frequency Range to 13.6 GHz with Optional Preamplifier The UTS7013A-NB covers 2 Hz – 13.6 GHz on a single chassis — no band switching, no external mixers, no second instrument for the higher-frequency portion of the range. The UTS7000A-P13 preamplifier is the paired sensitivity option for this chassis. With the preamplifier engaged, displayed average noise level reaches −167 dBm/Hz — the floor that small-signal characterization, near-noise-level demodulation, and weak-emitter EMI work depend on. Each chassis in the UTS7000A line has its own paired preamp matched to the chassis's frequency range; the P13 is correct for the 13.6 GHz chassis. 5G NR Demodulation Analysis The UTS7000A-NR option adds 5G New Radio demodulation analysis directly on the instrument. Combined with the UTS7013A-NB's 13.6 GHz frequency reach and the chassis's 20 MHz real-time capture window, the UTS7013A-NB supports commercial 5G NR characterization across the sub-6 GHz (FR1) commercial bands — including n78 (3.3–3.8 GHz), n79 (4.4–5.0 GHz), and the wider Wi-Fi 6E unlicensed 6 GHz spectrum — used in commercial mobile network development, fixed wireless access equipment, and wireless device characterization where the signal of interest fits within a 20 MHz capture span. FR2 millimeter-wave bands begin at 24.25 GHz and require a higher-frequency chassis in the UTS7000A line. Communications signal analysis display ×Communications signal analysis display Digital modulation analysis — constellation diagram with EVM measurement Vector Signal Analysis The UTS7000A-VSA option provides general-purpose vector signal analysis with constellation, EVM, and symbol-rate measurement across the major digital modulation families — PSK, QAM, FSK, MSK, and ASK variants. Symbol rate is set from 1 ksps up to the instrument's analysis bandwidth divided by symbol points. Used for protocol bring-up on custom radios, IQ-based modulation verification, and digital-radio R&D where the modulation scheme is not a standardized cellular waveform. ×Digital modulation analysis — constellation diagram with EVM measurement I/Q Signal Analyzer The UTS7000A-I/Q option captures complex baseband I and Q time-record data alongside the frequency-domain view. The captured I/Q record supports both time-domain and frequency-domain inspection of the same signal, useful for protocol-level debug, custom-modulation verification, and post-capture analysis in external tools where the raw IQ samples are needed. I/Q time-record capture display ×I/Q time-record capture display EMI Pre-Compliance Testing The UTS7000A-EMI option configures the instrument for EMI pre-compliance work with CISPR-style detectors (including quasi-peak), pre-defined limit lines, and meter-mode measurement at fixed frequencies. Pre-scan plus final-scan workflows let a development team identify probable emissions failures and characterize their spectral content before scheduling certified-chamber time. Conducted-emissions spans (Band A, Band B) and broader radiated-emissions sweeps are both supported on the same instrument. One-button phase noise analysis — dBc/Hz log-plot display Phase Noise Analysis The UTS7000A-PNM option provides one-touch phase noise measurement at user-selected offset frequencies, with dBc/Hz log-plot display. Used for oscillator characterization, synthesizer evaluation, and reference-clock qualification where the instrument's own phase noise floor (<−110 dBc/Hz) is well below the device under test. ×One-button phase noise analysis — dBc/Hz log-plot display Advanced Measurement Kit — TOI, OBW, Channel Power, ACPR, CNR, Spectrum Monitoring The UTS7000A-AMK option adds a set of one-touch power and spectral measurements for routine RF characterization work — third-order intercept (TOI), occupied bandwidth (OBW), channel power, adjacent-channel power ratio (ACPR), carrier-to-noise ratio (CNR), harmonic analysis, time-domain power, and spectrum monitoring. Each is a dedicated measurement screen rather than a manual sequence of marker placements, which is the practical difference for production-floor characterization and overnight automated sweeps. Advanced Measurement Kit — cycling through TOI, OBW, channel power, ACPR, CNR, harmonic, time-domain power, and spectrum monitoring measurements ×Advanced Measurement Kit — cycling through TOI, OBW, channel power, ACPR, CNR, harmonic, time-domain power, and spectrum monitoring measurements Analog modulation analysis — AM/FM/PM demodulation Analog and LTE Demodulation The UTS7000A-AMA option adds analog demodulation analysis for AM, FM, and PM signals, with measurement of carrier, modulation depth, frequency deviation, SINAD, and total harmonic distortion. The UTS7000A-FDD-LTE and UTS7000A-TDD-LTE options add 3GPP LTE demodulation for FDD and TDD signals respectively, with per-resource-block EVM, frame and slot synchronization, PDSCH and PUSCH characterization, and OFDM signal analysis. Each is a separate license and operates as a dedicated measurement mode on the instrument. ×Analog modulation analysis — AM/FM/PM demodulation Primary Applications 5G NR Sub-6 and Commercial Wireless Equipment Development The UTS7013A-NB's 13.6 GHz frequency reach covers commercial 5G NR sub-6 (FR1) bands and the broader sub-15 GHz commercial wireless spectrum used in commercial mobile network development, fixed wireless access equipment, and wireless device characterization. The UTS7000A-NR demodulation option and the UTS7000A-I/Q time-record option are the two most-used adds for commercial 5G NR work within the 20 MHz capture window of the narrow-band configuration. Wireless and IoT Protocol Bring-Up For 2.4 GHz and 5 GHz commercial bands — Wi-Fi 6 / 6E, Bluetooth, Zigbee, LoRa, and custom proprietary radios — the chassis pairs with the UTS7000A-VSA for digital modulation characterization and the UTS7000A-I/Q for time-record capture used in protocol-level debug and post-capture analysis. Narrow-band real-time analysis supports single-channel and slow-hopping signal capture within the 20 MHz window. EMI Pre-Compliance and Spectral Hygiene The UTS7000A-EMI option configures the instrument for conducted and radiated emissions pre-compliance work — CISPR-style detectors including quasi-peak, pre-defined limit lines, and pre-scan plus final-scan workflows. For power-electronics designs where switching-frequency emissions and harmonics need to be characterized before chamber time, the combination of EMI option plus the UTS7000A-AMK measurement kit (harmonic analysis, spectrum monitoring) supports a complete pre-compliance bench on one instrument. R&D Characterization and Spectrum Monitoring For general signal-analysis R&D work — oscillator and synthesizer phase-noise qualification, intermodulation distortion measurement, spurious search, weak-signal detection, and long-duration spectrum monitoring — the chassis's −167 dBm/Hz noise floor (with preamp), 100,001 sweep points, six trace memories, and real-time density-spectrum display cover the day-to-day workflows. The UTS7000A-PNM phase noise option and the UTS7000A-AMK measurement kit are the most-used adds for this work. Accessories and Family Options Real-time bandwidth expansion is not available in the narrow-band configuration. The B85 / B160 / B255 real-time bandwidth options are installable only on the 40 MHz wide-band configuration; for wideband real-time work, the UTS7013A wide-band chassis is the configuration to choose. Paired preamplifier option (frequency-matched to this chassis): UTS7000A-P13 — preamplifier for UTS7013A-NB and UTS7013A Measurement function options (software-licensed; compatible with all UTS7000A chassis including –NB): UTS7000A-NR — 5G NR demodulation analysis UTS7000A-VSA — vector signal analysis UTS7000A-I/Q — I/Q signal analyzer UTS7000A-EMI — EMI pre-compliance testing UTS7000A-PNM — phase noise measurement UTS7000A-AMK — advanced measurement kit UTS7000A-AMA — analog demodulation (AM/FM/PM) UTS7000A-FDD-LTE — LTE FDD demodulation UTS7000A-TDD-LTE — LTE TDD demodulation Frequently Asked Questions Can the real-time analysis bandwidth be upgraded later? No. The UTS7013A-NB is the narrow-band configuration with 20 MHz real-time bandwidth fixed at the factory and no upgrade path. For wideband real-time analysis up to 255 MHz, the wide-band UTS7013A is the configuration to choose — same chassis platform, software-expandable real-time bandwidth at 40 / 85 / 160 / 255 MHz. Which preamplifier do I order with the UTS7013A-NB? The UTS7000A-P13 is the matched preamplifier for the 13.6 GHz chassis. Each chassis in the UTS7000A line has its own frequency-matched preamp; using a preamp from a lower-frequency chassis would limit the sensitivity range you can use across the UTS7013A-NB's full span. Do the same measurement options work as on the wide-band configuration? Yes. All nine measurement options — NR, VSA, I/Q, EMI, PNM, AMK, AMA, FDD-LTE, TDD-LTE — install as software licenses on the UTS7013A-NB and operate identically to the wide-band configuration. The 20 MHz real-time bandwidth limit applies only to real-time spectrum analysis; the other measurement modes are unaffected. Is the tracking generator included or available as an option? The UTS7000A line does not include a tracking generator on any chassis. For scalar network analysis on a UNI-T signal-analyzer platform with a built-in tracking generator, the UTS5000A series is the alternate instrument. Does the UTS7013A-NB support remote programming and automation? Yes. The instrument supports SCPI programming over LAN and USB, with the standard interface set including USB 3.0 host, USB 2.0 host, USB-Device, LAN, HDMI, 10 MHz reference In/Out, external reference input, and two trigger inputs.
