UTS5000A-EMI EMI Pre-Compliance Measurement Option
Overview
The UTS5000A-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 UTS5000A Series spectrum analyzers. The same capability is offered on other UNI-T spectrum analyzer families: UTS1000B, UTS3000A, UTS3000B, 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.
