A mixed signal oscilloscope (MSO) is the ideal tool for the design and debug of today’s embedded systems providing the only way to see analog, digital and serial data signals simultaneously on one instrument as they occur in real time. Embedded system designers need to view signals into and out of devices such as microcontrollers, DSPs, FPGAs,ADCs, DACs, and transducers while ensuring proper timing and bus traffic.
The MS Series offers unmatched digital performance and is available in two models, the MS-500 and MS-250.
Designed to capture long records of the fastest digital signals, the MS-500 has a maximum input frequency of 500 MHz, while other MSOs are limited to 250 MHz. The long memory of 50 Mpts/Ch means that these fast signals can be captured for up to 25 ms at up to 2 GS/s sampling rate. On top of this raw performance, the MS-500 supports up to 36 channels — enough for all the ADDR, DATA, control lines and serial data busses. This makes it the perfect tool for embedded systems with 16-bit or 32-bit microcontrollers.
The MS-250 is the ideal tool for testing embedded systems with 8-bit microcontrollers or slower digital signals. With 250 MHz max input frequency, 18 channels and 10 Mpts/Ch memory the MS-250 is an outstanding value and provides a complete set of tools for embedded system testing.
