MSO8000HD-CTSUSB20 USB 2.0 Compliance Test Option
Overview
The MSO8000HD-CTSUSB20 runs automated USB 2.0 electrical compliance tests on an MSO8000HD Series oscilloscope, following the USB-IF specification.
Each test sets up the oscilloscope automatically, shows how to connect it to the device under test, and records the result against the limit.
The option is enabled by a software license keyed to the oscilloscope's serial number and is permanent for the life of the instrument.
What It Tests
Covers Low-, Full- and High-Speed signal quality for a device, host or hub: eye diagram, end-of-packet width, signal rate, edge monotonicity, jitter, edge rates and rise/fall time. High-Speed non-signal-quality tests include chirp, suspend, resume, reset, packet parameters and J/K and SE0 voltages, all against the USB-IF limits.
The UT-USB20-SQ-HD fixture does not cover receiver sensitivity, and power tests are not yet supported.
Key Features
- Automated tests β run a single test item or a full batch, with the oscilloscope configured for each item.
- Guided connection β a visual connection and setup diagram for each test.
- Reports β pass/fail status, test margins, parameter results and waveform snapshots.
- Test limits β the standard's limits, or limits you define.
- Repeat runs β re-test and compare rounds to check the effect of a design change.
- What else you need β an active differential probe of at least 2 GHz (UT-PD2500), two active single-ended probes of at least 2 GHz (UT-PA2000), the UT-USB20-SQ-HD USB 2.0 test fixture, and the USB-IF HSETT or XHSETT packet software on a PC.
Compatibility
For the MSO8000HD Series: MSO8804HD (8 GHz), MSO8604HD (6 GHz) and MSO8504HD (5 GHz).
Frequently Asked Questions
How is this option activated?
Buy the option from your UNI-T distributor with the oscilloscope's serial number. You receive a license certificate; register it on the License Activation page of the UNI-T website with the instrument serial number to get the license file. Copy the file to the root of a USB drive, connect it to the oscilloscope and install it from the Option Install menu.
Is the license permanent, or does it require renewal?
The license is permanent β a one-time purchase that stays active for the life of the instrument. No subscriptions, no annual renewals, and no expiration.
Do I need anything besides the option?
Yes: an active differential probe of at least 2 GHz (UT-PD2500), two active single-ended probes of at least 2 GHz (UT-PA2000), the UT-USB20-SQ-HD USB 2.0 test fixture, and the USB-IF HSETT or XHSETT packet software on a PC.
