Overview

The UNI-T UTS7013A is a 13.6 GHz signal analyzer for commercial wireless, IoT, EMI pre-compliance, and R&D characterization work. 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 is a 13.6 GHz member of the UTS7000A wide-band signal analyzer line. Real-time spectrum analysis is included as a base instrument capability with 40 MHz analysis bandwidth standard, software-expandable to 85, 160, or 255 MHz via the B-series license options. A 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 narrow-band –NB configuration when your signals do not require real-time bandwidth beyond 20 MHz — narrow-channel monitoring, single-carrier characterization, slow-hopping signal capture, or EMI pre-compliance on conducted-emissions spans. 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.

UNI-T UTS7013A Details

Frequency Range to 13.6 GHz with Optional Preamplifier

The UTS7013A 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.

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.

Primary Applications

5G NR Sub-6 and Commercial Wireless Equipment Development

The UTS7013A'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, the real-time bandwidth options up to 255 MHz, and the I/Q time-record option are the three pieces a typical commercial 5G NR bench will use together.

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. Real-time analysis bandwidth options support wideband channels and frequency-hopping signal capture.

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.

Frequently Asked Questions

Which preamplifier do I order with the UTS7013A?

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's full span.

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.

Can the real-time analysis bandwidth be expanded after purchase?

Yes — the UTS7013A ships with 40 MHz real-time bandwidth and can be expanded by adding the UTS7000A-B85 (85 MHz), UTS7000A-B160 (160 MHz), or UTS7000A-B255 (255 MHz) bandwidth options. These are field-installable software licenses — purchase, register, and install via the chassis Option Install menu.

Are the measurement options installed in the factory, or can I license them later?

The nine measurement options — 5G NR, VSA, I/Q, EMI, PNM, AMK, AMA, FDD-LTE, TDD-LTE — install as software licenses on the instrument and can be added at any time after purchase. Each option installs and activates independently.

Does the UTS7013A 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.
