UTS3000A-EMI EMI Pre-Compliance Measurement Option
Overview
The UTS3000A-EMI adds EMI pre-compliance measurement — quasi-peak detectors, limit lines (CISPR, FCC, EN, MIL-STD-461, VCCI), automated scans, and pass/fail reporting. Catch failures early and save weeks of redesign. The option is enabled by a software license keyed to the spectrum analyzer's serial number and is permanent for the life of the instrument.
Key Features
- EMI Detectors — Quasi-peak, EMI average, peak, negative peak per CISPR 16.
- Limit Lines — CISPR 11/22/32, FCC Part 15, EN 55011/55032, MIL-STD-461, VCCI, and more.
- Automated Scans — Scan-search-measure workflows — peaks identified, quasi-peak measured, results compiled automatically.
- Pass/Fail Reports — On-instrument compliance reports with margin analysis.
- Pair with UTS-EMI01 — Combine with UTS-EMI01 near-field probes to locate emission sources on PCBs.
- Lifetime License Activation — activate once, owned for the life of the instrument. No subscriptions, no renewals, no maintenance fees.
When You Need This Option
The option fits the following workflows:
- Pre-Compliance — Run EMI scans with FCC/CISPR limits during prototyping — find issues before the compliance lab.
- Failed Test Troubleshooting — Reproduce compliance failures on your bench, iterate on filter designs, measure improvements in real time.
Compatibility
This option is compatible with all UTS3000A Series spectrum analyzers: UTS3015A (1.5 GHz), UTS3026A (2.6 GHz), UTS3036A (3.6 GHz), UTS3046A (4.5 GHz). The same capability is offered on other UNI-T spectrum analyzer families: UTS1000B, UTS3000B, UTS5000A, UTS7000A.
Frequently Asked Questions
Is this sufficient for formal compliance?
Pre-compliance screening — catches most issues early. Formal testing requires a certified lab with calibrated antennas and chambers.
How is this option activated?
The option is enabled by a software license keyed to the spectrum analyzer's serial number. After purchase, the license is registered on the UNI-T website to generate the license file, which is then loaded onto the spectrum analyzer from a USB drive through the option-install menu. Refer to the spectrum analyzer's user manual for the step-by-step procedure.
Is the license permanent, or does it require renewal?
The license is permanent — a one-time purchase that stays active for the life of the instrument. No subscriptions, no annual renewals, and no expiration.
