MSO/UPO3000CS-COM PC serial bus trigger and analysis (RS232/UART)
Overview
The MSO/UPO3000CS-COM adds RS232/UART serial bus triggering, decoding, and search to your MSO/UPO3000CS Series oscilloscope — the most fundamental serial interface in electronics, used for debug consoles, GPS modules, Bluetooth modules, and inter-processor communication.
See what's actually happening on a serial port — not just what a terminal shows, but electrical signal and decoded data together.
Key Features
- UART/RS232 Triggering — Trigger on data bytes, parity errors, framing errors, or break conditions.
- Real-Time Frame Decoding — Decoded UART frames display on the waveform with data bytes, parity, and framing identified.
- Configurable Parameters — Standard baud rates (1200 to 921600+), 5-9 data bits, parity, 1-2 stop bits.
- Dual TX/RX Decoding — Decode both transmit and receive lines for full-duplex analysis.
- Software License Activation — License key applied through the instrument menu. No hardware changes, no downtime — enter the key and start decoding.
When You Need This
Debug Console Capture
Trigger on a specific error string in UART boot messages and capture surrounding traffic with full waveform context.
GPS Module Integration
Decode NMEA sentences to verify baud rate and data integrity when the module won't communicate with the host.
Compatible Instruments
This option is compatible with all UPO1000CS and MSO3000E Series oscilloscopes.

Frequently Asked Questions
Should I buy this individually or get a bundle?
If you only need RS232/UART, the individual license at $236 is the most economical. The BND bundle ($715) includes every protocol at the deepest discount.
How is this option activated?
You receive a license key after purchase. Enter the key in the instrument's menu under System → Options → Install. The capability is available immediately — no reboot, no hardware modification, no factory service required.
Is the license permanent or subscription-based?
All UNI-T software option licenses are permanent, one-time purchases. Once activated, the option remains available for the life of the instrument. No annual renewals or subscription fees.
