For RF design work above the common sub-3 GHz bands — higher-order harmonics, wideband spurious search, and signals that need fine frequency resolution across a wide span — the deeper sweep and the 8.4 GHz reach of the UTS3084T+ are the reason to choose this pair. Typical displayed average noise level reaches −165 dBm with the preamp on (a shared series figure for both models), phase noise is −98 dBc/Hz typical at 10 kHz offset, and full-amplitude accuracy is under 0.7 dB. The tracking generator is built in and standard; analog demodulation, the advanced measurement kit and EMI pre-compliance are field-installable options. A 10.1-inch 1280×800 capacitive touch screen and full SCPI control over USB and LAN support scripted overnight sweeps across frequency, level and span. Choosing Your Model — UTS3000T+ Performance-Series The UTS3000T+ name spans two materially different instrument classes. The four models below do not share the same sweep engine, trace count or demodulation capability — the differences go well beyond frequency reach. Compare the full series before selecting: Specification UTS3015T+ UTS3032T+ UTS3036T+ UTS3084T+ Frequency range 9 kHz – 1.5 GHz 9 kHz – 3.2 GHz 9 kHz – 3.6 GHz 9 kHz – 8.4 GHz Sweep (scan) points 10,001 10,001 40,001 40,001 Traces 4 4 6 6 Analog demodulation (option) AM, FM AM, FM AM, FM, PM AM, FM, PM Tracking generator range 100 kHz – 1.5 GHz 10 MHz – 3.2 GHz 100 kHz – 3.6 GHz 100 kHz – 6 GHz Resolution bandwidth 1 Hz – 3 MHz 1 Hz – 3 MHz 1 Hz – 3 MHz 1 Hz – 3 MHz Built-in tracking generator Standard Standard Standard Standard Within the UTS3015T+/UTS3032T+ class, choose by frequency reach (1.5 GHz vs 3.2 GHz). Within the UTS3036T+/UTS3084T+ class, choose 3.6 GHz or 8.4 GHz reach. Across classes the UTS3036T+/UTS3084T+ models add a 40,001-point sweep (4× the depth), six traces instead of four, and PM demodulation in addition to AM/FM — confirm which class a model belongs to before assuming a shared specification. Key Features Spectrum analysis to 3.6 GHz or 8.4 GHz — 9 kHz lower edge to 3.6 GHz (UTS3036T+) or 8.4 GHz (UTS3084T+), reaching higher harmonics and wideband signals the sub-3 GHz class cannot. 40,001 sweep points, six traces — Four times the sweep depth of the entry pair, with six independent traces for simultaneous live, reference and limit comparison. Built-in tracking generator — Standard on both models — scalar network response on filters, amplifiers and cables; TG output to 6 GHz on the UTS3084T+. −165 dBm typical DANL (preamp on) — Low displayed average noise level (10–200 MHz band) for weak-signal and low-level emissions work — a shared series figure, the same for both models. Reflection measurement (S11) — Return loss, VSWR and reflection coefficient with the optional VSWR bridge. 1 Hz to 3 MHz RBW, < 4.8:1 shape factor — Fine resolution and selectivity for closely spaced unequal-amplitude signals. Phase noise to −110 dBc/Hz at 1 MHz — Close-in phase-noise figures suited to oscillator and synthesizer characterization. Full SCPI remote control — USB and LAN (VXI11) for automated frequency/level/span sweeps. EMI pre-compliance and analog demodulation options — CISPR-aware screening with quasi-peak/EMI-average detectors; AM/FM/PM demodulation with SINAD and THD readout. UNI-T UTS3000T+ Performance-Series Details Frequency Reach to 8.4 GHz The UTS3036T+ sweeps 9 kHz to 3.6 GHz; the UTS3084T+ to 8.4 GHz. The higher ceiling captures the third and higher harmonics of sub-3 GHz carriers and wideband spurious content that a 3 GHz-class analyzer cannot reach. 9 kHz to 8.4 GHz coverage×9 kHz to 8.4 GHz coverage 40,001-Point Sweep Each trace carries 40,001 points — four times the entry pair — so a wide span still resolves narrow signals without sacrificing the span to keep frequency resolution. This is the practical difference when searching a multi-GHz window for a single spur. 40,001-point sweep×40,001-point sweep Six Traces and Detector Modes Six independent traces with Sample, Peak, Negative, Normal and Average detectors allow live, max-hold, reference and limit traces on screen at once — useful when comparing a measured spectrum against a stored mask. Six traces, five detectors×Six traces, five detectors Sensitivity and Phase Noise Typical displayed average noise level reaches −165 dBm with the preamp on (10–200 MHz band) — a shared series figure for both models. Phase noise is −98 dBc/Hz typical at 10 kHz and reaches −110 dBc/Hz at 1 MHz offset on the UTS3084T+, relevant when measuring a clean source close to the carrier. DANL and close-in phase noise×DANL and close-in phase noise Resolution Bandwidth and Selectivity RBW 1 Hz to 3 MHz in 1-3-10 steps with a < 4.8:1 shape factor resolves a weak product sitting next to a strong carrier. 1 Hz to 3 MHz RBW×1 Hz to 3 MHz RBW Reflection Measurement With the optional VSWR bridge and the built-in tracking source, the analyzer measures S11 return loss, reflection coefficient and VSWR after an Open calibration — antenna and cable verification on the same instrument. S11 / return loss / VSWR×S11 / return loss / VSWR EMI Pre-Compliance Screening (Option) With the optional UTS3000-EMI kit the analyzer operates as a CISPR-aware screening receiver: −6 dB resolution bandwidths of 200 Hz, 9 kHz, 120 kHz and 1 MHz; Peak, Negative-Peak, Quasi-Peak, EMI-Average and Average detectors; up to three concurrent meter traces; and editable limit-line sets for FCC, EN, MIL-STD-461, DO-160, VCCI and custom standards. A Scan / Search / Measure sequence with output report supports near-field-probe emissions screening before committing to chamber time. CISPR-aware EMI frequency scan×CISPR-aware EMI frequency scan Analog Demodulation Analysis (Option) The optional UTS3000-AMA kit adds AM, FM and PM demodulation. Modulation rate covers 20 Hz to 100 kHz; AM depth 5–95%; FM offset 1 kHz to 400 kHz; PM phase deviation 0.2 to 6.28 rad. The result window reports modulation depth, carrier power, modulation frequency, SINAD and THD — enough to verify a transmitter's modulation quality from the same bench. AM/FM/PM demodulation, SINAD/THD×AM/FM/PM demodulation, SINAD/THD Advanced One-Key Measurements (Option) The optional UTS3000-AMK kit adds channel power, power spectral density, adjacent-channel power, occupied bandwidth, transmit frequency error, zero-span (time-domain) power, carrier-to-noise ratio, third-order intercept and harmonic measurement to the 10th order, plus a spectrogram monitor — the transmitter-test set used in design verification. One-key transmitter measurements×One-key transmitter measurements Applications RF and Wireless Design Engineering Above 3 GHz the work is harmonic and spurious search, wideband signal characterization, and source verification. The 8.4 GHz reach of the UTS3084T+ captures the higher harmonics of a sub-3 GHz design; the 40,001-point sweep keeps narrow signals resolved across a multi-GHz span; and the close-in phase-noise figures support oscillator and synthesizer characterization. Full SCPI over LAN runs the level- and frequency-stepped sweeps a characterization report needs, unattended. Pre-Compliance and Multi-Function Test Benches For a lab that needs more than one instrument's worth of capability per bench, this pair consolidates spectrum analysis, scalar network response via the built-in tracking generator, reflection measurement, AM/FM/PM demodulation and CISPR-aware EMI screening into one instrument. Early emissions screening with a near-field probe set catches problems before chamber time; the advanced-measurement kit covers the transmitter test set for design verification — all option installs, no recurring license. Accessories and Family Options The tracking generator is built in on every UTS3036T+ / UTS3084T+ model. Field-installable options: UTS3000-AMA Analog Demodulation, UTS3000-AMK Advanced Measurement Kit, UTS3000-EMI EMI Pre-Compliance. The tracking generator is standard — it is not an added option on the T+ line. Frequently Asked Questions What does the UTS3036T+/UTS3084T+ add over the lower-frequency models in this series? Frequency reach, sweep depth and trace count. The UTS3036T+ and UTS3084T+ reach 3.6 GHz and 8.4 GHz with a 40,001-point sweep and six traces; the UTS3015T+/UTS3032T+ models reach 1.5/3.2 GHz with a 10,001-point sweep and four traces, and their analog-demod option is AM/FM only (no PM). The Choosing Your Model table above shows the full series comparison. What is the difference between the UTS3036T+ and the UTS3084T+? Frequency ceiling and tracking-generator range. The UTS3036T+ covers to 3.6 GHz with a TG to 3.6 GHz; the UTS3084T+ covers to 8.4 GHz with a TG to 6 GHz and slightly better close-in phase noise.

Can it screen for EMI before a formal compliance test? With the optional UTS3000-EMI kit it provides CISPR-bandwidth RBWs, quasi-peak and EMI-average detectors and editable limit lines (FCC, EN, MIL-STD-461, DO-160, VCCI, custom) for near-field-probe screening ahead of an accredited run.
