• Communication testing
• Embedded system verification

The integrated Bode plot analysis further simplifies loop response testing for switching power supplies and control systems.

Mixed Signal Oscilloscope Capability

The DHO924S supports optional 16 digital logic channels through the PLA2216 logic probe, transforming the oscilloscope into a mixed signal oscilloscope (MSO). This enables simultaneous analysis of analog and digital signals for embedded system debugging and digital electronics verification

Supported serial bus decoding includes:

• I2C
• SPI
• UART / RS232
• CAN
• LIN

These advanced protocol analysis features simplify troubleshooting of communication interfaces in automotive electronics, industrial automation systems, IoT devices, and embedded applications.
