Overview

The UNI-T UTS7013A Interceptor-Series signal analyzer delivers professional spectrum analysis from 2 Hz to 13.6 GHz with exceptional -167 dBm/Hz sensitivity, guaranteed 100% Probability of Intercept, and upgradeable real-time bandwidth from 40 MHz to 255 MHz. Engineered for wireless development, EMI pre-compliance testing, and comprehensive RF characterization, the UTS7013A provides specifications typically found in instruments costing significantly more—exceptional sensitivity for weak signal detection, guaranteed signal capture for transient analysis, and extended frequency coverage for versatile measurement applications.

You're an engineer who needs professional measurement capability without premium pricing. The UTS7013A delivers 4 dB better sensitivity than competing mid-range analyzers, 10× wider maximum real-time bandwidth, and a 2 Hz starting frequency that enables EMC testing and power electronics analysis impossible with typical 9 kHz minimum frequency instruments. Whether characterizing Wi-Fi 6/6E devices, validating 5G NR transmitters, hunting intermittent EMI emissions, or analyzing IoT wireless protocols, the UTS7013A provides the measurement confidence and versatility your applications demand.

The UTS7013A delivers -167 dBm/Hz typical DANL (Displayed Average Noise Level)—4 dB better than competing mid-range analyzers typically specifying -163 dBm/Hz. This sensitivity advantage isn't a minor specification detail; it directly impacts your measurement capability and confidence.

That extra 4 dB means you can detect spurious emissions 4 dB weaker, measure receiver sensitivity with 4 dB more margin, and identify interference sources that competing analyzers simply cannot see above their own noise floor. For every 6 dB improvement in DANL, you effectively double your detection range for weak signals.

Practical example: Testing a Bluetooth Low Energy module transmitting at +4 dBm, you need to verify spurious emissions down to -60 dBm (64 dB below carrier). With -167 dBm/Hz DANL, you have 107 dB dynamic range for this measurement. With a competitor's -163 dBm/Hz, only 103 dB. That 4 dB margin is the difference between confident measurements and results limited by instrument noise.

For applications like IoT wireless (LoRa, NB-IoT) operating at very low power levels, receiver sensitivity testing requiring measurements near -120 dBm, or spurious emission hunting in crowded spectrum, the exceptional sensitivity provides measurement capability that competing instruments cannot match.

Modern wireless systems use frequency hopping (Bluetooth), burst transmissions (5G TDD), and discontinuous operation (duty-cycled IoT). Traditional swept spectrum analyzers scan through frequencies sequentially—creating measurement gaps where brief signals are completely missed. You see gaps in the spectrum where active transmissions exist, or measurements show artificially low power because the analyzer wasn't looking at that frequency when the signal transmitted.

The UTS7013A's 100% Probability of Intercept specification guarantees capture of any signal lasting 4.5 μs or longer within its 255 MHz real-time bandwidth. This means the analyzer continuously monitors the entire frequency span simultaneously—no scanning gaps, no missed signals. Any RF event lasting longer than 4.5 μs will be detected with full amplitude accuracy, guaranteed.

Why this matters for your applications:

• Bluetooth frequency hopping: Bluetooth hops across 79 channels, dwelling 625 μs per hop. The UTS7013A captures every single hop within the monitoring span. Traditional swept analyzers miss most hops entirely.
• 5G TDD switching: 5G NR uses time-division duplex with rapid uplink/downlink switching. The 100% POI guarantee ensures you capture switching transients that indicate transmitter turn-on/turn-off behavior.
• Intermittent EMI emissions: Clock switching noise, burst transmission interference, and transient power supply events occur sporadically. The UTS7013A captures these intermittent emissions that swept-only analyzers miss—preventing costly surprises during certification testing.
• Pulsed radar: Radar pulse widths range from 0.1 to 10 μs. The 4.5 μs POI specification ensures reliable capture of pulses ≥5 μs.

Most competing mid-range analyzers don't specify 100% POI at all—leaving you without guaranteed capture assurance for transient signals. The UTS7013A's POI guarantee provides measurement certainty for elusive signals.

Modern wireless standards use increasingly wide channel bandwidths. Wi-Fi 6E operates with 160 MHz channels in the 6 GHz band. 5G NR uses carriers up to 100 MHz wide. Multi-carrier satellite systems occupy hundreds of MHz. To capture these wideband signals without gaps, you need real-time analysis bandwidth that spans the complete channel.

The UTS7013A provides upgradeable real-time bandwidth:

• 40 MHz standard: Handles Wi-Fi 20/40 MHz channels, LTE carriers up to 20 MHz, all IoT protocols (Bluetooth, Zigbee, LoRa)
• 85 MHz option: Captures Wi-Fi 80 MHz channels with margin
• 160 MHz option: Complete Wi-Fi 6E 160 MHz channel capture
• 255 MHz option: Multiple 5G NR carriers simultaneously, wideband satellite transponders, maximum instantaneous capture bandwidth

Investment protection: Start with 40 MHz standard bandwidth (already wider than typical 25 MHz competition), then upgrade to 85/160/255 MHz when your applications demand wider coverage. The upgradeable architecture means you're not locked into today's bandwidth—your analyzer grows with evolving wireless standards.

Competing mid-range analyzers typically offer only 25 MHz with no upgrade path. The UTS7013A provides 40 MHz standard (60% wider) with 10× expansion capability through field-installable upgrades.

Most spectrum analyzers start at 9 kHz, immediately limiting their utility for EMC conducted emissions testing (which often starts below 9 kHz) and completely preventing power electronics harmonic analysis from fundamental frequencies. The UTS7013A starts at 2 Hz—4,500× lower than typical analyzers.

When the extended range matters:

• EMC conducted emissions below 9 kHz: Automotive CISPR 25 and military MIL-STD-461 standards specify conducted emission limits starting below 9 kHz. The 2 Hz capability provides complete coverage where competing analyzers have zero capability.
• Power electronics harmonic analysis: Switching power supplies and motor drives generate harmonics from fundamental frequencies through high orders. Complete analysis from DC fundamental through switching harmonics requires extended low-frequency coverage.
• Comprehensive system testing: When characterizing products containing both wireless transceivers and switching power supplies, the 2 Hz to 13.6 GHz range means one analyzer handles both RF and power analysis without switching instruments.

Reality check: Most RF engineers spend >95% of time above 100 MHz. The 2 Hz capability is a versatility bonus for when you need complete system analysis from power fundamentals through RF harmonics—not the primary purchase driver. But when you need measurements below 9 kHz, no competing mid-range analyzer offers this capability.
