UTS7000A Interceptor-Series Signal Analyzer — Buyer's Guide
Which Interceptor Is Right for You?
The UTS7000A Interceptor-Series delivers professional-grade signal analysis from 2 Hz to 40 GHz with real-time spectrum analysis, 100% Probability of Intercept (POI), and exceptional -167 dBm/Hz sensitivity — specifications typically found on instruments costing two to three times more. Every model in the series shares the same core measurement engine, display, and build quality. The differences come down to two simple choices: how high in frequency do you need to measure, and how wide a real-time bandwidth do you need?
This guide will walk you through those decisions in plain language so you can confidently choose the right model and options for your work.
What Every Interceptor-Series Model Shares
Before comparing models, it helps to know that every UTS7000A — regardless of frequency or bandwidth variant — includes these core capabilities:
Starting Frequency
2 Hz — 4,500× lower than typical 9 kHz analyzers
Sensitivity (DANL)
-167 dBm/Hz typical — among the best in class
100% POI
Guaranteed signal capture — no transient escapes
Phase Noise
< -110 dBc/Hz (1 GHz, 10 kHz offset, typical)
Sweep Points
Up to 100,001 for ultra-fine resolution
Display
11.6" multi-touch HD (1920 × 1080)
Connectivity
LAN (GigE), USB 3.0, GPIB optional — SCPI remote control
Warranty
5 years — parts, labor, return shipping
In short, the measurement quality is the same across the lineup. You're simply choosing how much frequency range and real-time bandwidth your applications require.
Decision 1: Choose Your Frequency Range
UTS7000A models are available in four maximum frequency configurations. Every model starts at 2 Hz — you're choosing how high it goes. Pick the lowest frequency range that covers your applications; you'll get the same sensitivity, phase noise, and measurement quality regardless of model.

Tip: If you anticipate frequency needs growing over the next few years, consider stepping up one model. Frequency range cannot be upgraded after purchase.
Decision 2: Standard or Narrowband?
Each frequency model is available in two real-time bandwidth configurations. This is the second — and often the most cost-impactful — decision you'll make.
Standard Models (Upgradeable)
UTS7013A · UTS7026A · UTS7032A · UTS7040A
Ship with 40 MHz real-time analysis bandwidth. Can be upgraded at time of purchase to 85, 160, or 255 MHz via factory-installed options (B85, B160, B255).
Choose Standard if you:
• Work with wideband signals (Wi-Fi 80/160 MHz channels, 5G NR carriers >20 MHz, wideband radar chirps, multi-carrier satellite transponders)
• Need to capture wideband transient events in real-time
• Want the flexibility to upgrade bandwidth later as applications expand
Narrowband Models (-NB)
UTS7013A-NB · UTS7026A-NB · UTS7032A-NB · UTS7040A-NB
Fixed at 20 MHz real-time analysis bandwidth. Cannot be upgraded.
Choose Narrowband if you:
• Primarily work with narrowband signals (single LTE carriers ≤20 MHz, individual IoT channels, CW signals, component testing)
• Need strong swept-spectrum analysis but don't require ultra-wide real-time capture
• Are focused on EMC pre-compliance where 20 MHz is typically sufficient
• Want a lower initial investment for the same frequency coverage
Real-Time Bandwidth Options at a Glance (Standard Models Only)
| Option | Bandwidth | Typical Use Case |
|---|---|---|
| Standard (included) | 40 MHz | Wi-Fi 20/40 MHz, LTE carriers ≤20 MHz, IoT protocols, EMC testing |
| UTS7000A-B85 | 85 MHz | Wi-Fi 80 MHz channels, 5G carrier aggregation, FMCW radar chirps |
| UTS7000A-B160 | 160 MHz | Wi-Fi 6E 160 MHz channels, wideband 5G NR carriers, satellite transponders |
| UTS7000A-B255 | 255 MHz | Maximum real-time capture, multi-carrier analysis, widest 5G NR, fastest POI |
Important: Bandwidth options are only available on standard models. Narrowband (-NB) models have fixed 20 MHz bandwidth and cannot be upgraded. If there is any chance you'll need wider bandwidth in the future, start with a standard model.

Covers Ku, K, and Ka-band satellite frequencies. The VSA option enables demodulation of custom satellite modulations (PSK, QAM, etc.). The UTS7040A extends into Q-band for next-generation satellite systems.
Power Electronics / Motor Drives
UTS7013A-NB
The 2 Hz starting frequency is the key differentiator here — analyze switching power supply harmonics, motor drive emissions, and inverter performance from the fundamental through high-order harmonics, all in one instrument. Narrowband is typically sufficient since most power signals are narrowband.
General RF Lab / Education
UTS7013A (standard)
The most versatile entry point: 2 Hz to 13.6 GHz with 40 MHz real-time bandwidth covers the vast majority of RF lab work. Upgradeable bandwidth provides future flexibility. Add software options as curriculum or project needs evolve.
Why Choose the Interceptor-Series?
2 Hz Starting Frequency
Most signal analyzers start at 9 kHz. The UTS7000A starts at 2 Hz — enabling power electronics analysis, low-frequency EMC conducted emissions, and complete system characterization from DC fundamentals through RF, all in one instrument. No competing mid-range analyzer offers this capability.
100% Probability of Intercept
Every model guarantees 100% POI — meaning no signal event is missed during real-time analysis. Transient interference, frequency-hopping signals, and intermittent emissions are captured with certainty, not probability. Critical for EMC testing and wireless debug where "missed" signals mean missed problems.
Professional Sensitivity
At -167 dBm/Hz typical DANL, the UTS7000A matches or exceeds many premium-brand analyzers in sensitivity — enabling weak signal detection, spurious emission hunting, and accurate receiver sensitivity measurements without a premium price tag.
5-Year Warranty
Every UTS7000A ships with a 5-year warranty covering parts, labor, and return shipping — two years longer than the industry-standard 3-year warranty. Lower total cost of ownership and long-term confidence in your investment.
Frequently Asked Questions
Can I upgrade the frequency range after purchase?
No. Frequency range is hardware-determined and fixed at the time of manufacture. If you're uncertain, select the next higher frequency model — the sensitivity and measurement quality are identical across all models.
Can I upgrade bandwidth on a narrowband (-NB) model later?
No. The -NB models have a fixed 20 MHz real-time bandwidth architecture that cannot be expanded. If there is any possibility you'll need wider bandwidth in the future, choose a standard model — even at 40 MHz standard, you preserve the upgrade path to 85, 160, or 255 MHz.
Can software options be added after purchase?
Yes. All software options (EMI, NR, LTE, VSA, I/Q, PNM, AMA, AMK) can be added to any UTS7000A model at any time through software licensing. You're never locked out of adding capabilities later.
What operating system does the UTS7000A run?
Ubuntu Linux ships as the standard operating system. Windows 10 is available as an optional configuration. Both support SCPI remote control over LAN and USB.
Is the UTS7000A suitable for automated test systems?
Yes. Full SCPI remote programming is supported over LAN (GigE), USB 3.0, and optional GPIB. The instrument integrates into standard automated test environments alongside other SCPI-compatible equipment.
Are there any purchasing restrictions?
No restrictions for commercial applications — consumer electronics, automotive, telecom, IoT, satellite, test labs, and universities can purchase and deploy UTS7000A equipment without limitations. Defense and aerospace contractors working on classified or export-controlled programs may have separate procurement requirements.
What's included in the 5-year warranty?
Parts, labor, and return shipping for the full 5-year term. No registration or extended warranty purchase required — it's standard on every unit.
Professional signal analysis from 2 Hz to 40 GHz — choose the Interceptor that fits your mission.
