Overview

The UTS3015T+ and UTS3032T+ bring 1.5 GHz and 3.2 GHz spectrum analysis, a built-in tracking generator, and reflection measurement into a single bench instrument under two thousand dollars. For a small hardware team or a contract test bench, that means one box covers signal search, scalar network checks, and pre-compliance screening without three separate purchases.

Both models hold a typical displayed average noise level to −161 dBm (preamp on, a shared series figure), phase noise below −98 dBc/Hz at 10 kHz offset, and full-amplitude accuracy under 0.7 dB — numbers that hold up under real measurement conditions, not peak-only figures. A 10.1-inch 1280×800 capacitive touch screen and full SCPI control over USB and LAN make the instrument scriptable from day one.

Tracking generator is built in on every T+ model — it is the defining difference of the T+ line and is standard, not an added option. Analog demodulation, the advanced measurement kit, and EMI pre-compliance remain field-installable options when a project needs them.

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:

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 Coverage and the Built-in Tracking Generator

The UTS3015T+ sweeps 9 kHz to 1.5 GHz and the UTS3032T+ to 3.2 GHz. Both carry a built-in tracking generator (−40 dBm to 0 dBm output, 0.5 dB resolution), so a swept frequency-response measurement on a filter or amplifier is set up on the analyzer itself rather than wired to an external generator.

Sensitivity for Weak-Signal Work

With the preamp enabled, typical displayed average noise level reaches −161 dBm (500 kHz to 200 MHz band). This is a shared series figure — both models hold the same typical noise floor at their respective top frequencies. A low noise floor is what lets a small signal be seen rather than buried, which matters for spur hunting and low-level emissions checks.

Resolution Bandwidth and Selectivity

RBW is settable from 1 Hz to 3 MHz in 1-3-10 steps. The < 4.8:1 (60 dB/3 dB) shape factor resolves adjacent signals of unequal amplitude — the case where a strong carrier would otherwise mask a nearby weak product.

×RBW selectivity, unequal-amplitude signals

10,001-Point Sweep

Each trace carries 10,001 points across the selected span, giving the frequency resolution needed to catch narrow signals that a coarser sweep would step over.

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, a marker on the trace reads the value at any frequency — enough for antenna tuning and cable-fault checks without a dedicated VNA.

10.1-inch Multi-Touch Operation

The 1280×800 capacitive screen supports drag, expand and zoom directly on the trace, with a fixed menu layout that keeps common settings one or two presses away.

Applications

Contract Test Labs and Design Consultancies

For a single-digit-engineer shop, bench space and budget are both finite. One UTS3015T+ or UTS3032T+ covers signal search, scalar network response with the built-in tracking generator, return-loss checks with the reflection-measurement bridge, and — with the EMI option — early conducted/radiated screening before a formal CISPR run. SCPI over LAN drops it straight into a Python or LabVIEW acceptance-test procedure. No per-feature license conversations: the options are one-time installs, not recurring fees.

Bench RF Design and Validation

On a design bench, the same instrument verifies oscillator output, checks harmonic and spurious content against a target, characterizes a filter or matching network with the tracking generator, and confirms antenna match with the VSWR bridge. The < 0.7 dB full-amplitude accuracy and −161 dBm typical DANL mean the numbers used in a design-verification report hold up under the conditions they were measured in.

Specifications

Accessories and Family Options

The tracking generator is built in on every UTS3015T+ / UTS3032T+ 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

Does the tracking generator cost extra on the T+?

No. The tracking generator is built in and standard on every UTS3000T+ model, including the UTS3015T+ and UTS3032T+. It is the defining feature of the T+ line.

What is the difference between the UTS3015T+ and the UTS3032T+?

Frequency reach and sensitivity. The UTS3015T+ covers 9 kHz to 1.5 GHz; the UTS3032T+ covers 9 kHz to 3.2 GHz. Both models share the same typical noise floor at their top frequencies, plus the same 10,001-point sweep engine, four traces, RBW range, touch interface and built-in tracking generator. The difference is frequency reach: 1.5 GHz versus 3.2 GHz. See Choosing Your Model above.

Can it do EMI pre-compliance?

With the optional UTS3000-EMI kit, yes. It adds CISPR-bandwidth RBWs (200 Hz, 9 kHz, 120 kHz, 1 MHz), quasi-peak and EMI-average detectors and editable limit lines for screening with a near-field probe set before a formal compliance run.

How is it controlled remotely?

Full SCPI over USB or LAN (VXI11). It integrates with Python, LabVIEW and MATLAB through standard VISA.

Warranty
