Frequently Asked Questions (FAQ)
❓ What is the UT-M15 Logic Probe?
The UT-M15 Logic Probe is a digital channel expansion accessory for UNI-T mixed signal oscilloscopes (MSOs). It adds up to 16 digital inputs, allowing you to capture, trigger, and analyze digital signals alongside your oscilloscope’s analog channels. This turns your UNI-T MSO into a powerful mixed-signal debug tool for embedded systems, automotive electronics, aerospace systems, and more.
❓ Why would I want digital channels on my oscilloscope?
With the UT-M15, you can view analog waveforms (voltages, signals, noise, power rails) at the same time as digital bus activity (I²C, SPI, UART, CAN, LIN, etc.). This saves time, improves troubleshooting, and makes it easier to understand system-level behavior. Instead of using a separate logic analyzer, the UT-M15 integrates everything directly into your UNI-T MSO oscilloscope, ensuring precise time correlation between analog and digital signals.
❓ Do I really need the UT-M15 Logic Pod?
If you are only testing simple analog circuits, you can use your oscilloscope without it. But if you are working with embedded systems, microcontrollers, or communication buses, the UT-M15 is almost essential. It lets you:
- Debug firmware-hardware interactions
- Capture protocol data like CAN, SPI, or I²C
- Validate timing margins in digital circuits
- Correlate digital control signals with analog outputs
For students, it’s an opportunity to learn real-world mixed-signal debugging skills. For professional engineers, it’s a productivity booster that makes troubleshooting faster and more reliable.
