Tektronix has released the new MSO2000 mixed-signal and DPO2000 digital phosphor oscilloscopes. The new series provide powerful tools to simplify the debug of mixed-signal designs, including Wave Inspector search and navigation tools, automatic decoding of serial data buses, and FilterVu variable low-pass filters to reduce unwanted noise from signals, all in a portable, affordable package.
With bandwidths up to 200 MHz, the new series complements the existing MSO4000, DPO4000 and DPO3000 oscilloscope series models for engineers working on embedded system designs.
Virtually every electronic product designed and produced today is an embedded system and may contain microprocessors, microcontrollers, DSPs, RAM, Flash, EEPROMs, FPGAs, ADCs, DACs and other I/O. In recent years, embedded system designs have replaced parallel buses with serial data buses such as I²C, SPI, RS232, CAN and LIN. On a serial bus, a single signal may include address, control, data and clock information; the complexity presents significant debug challenges for design engineers.
The MSO2000 and DPO2000 series address these problems with integrated serial data triggering, protocol decoding and analysis capabilities in an entry-level oscilloscope. Furthermore, the MSO2000 provides the ability to time-correlate analog and digital signals with up to four analog and 16 digital channels, for troubleshooting the mixed-signal portions of embedded systems. The scopes are ideally suited to embedded designers and educators teaching design principles.
The MSO2000 and DPO2000 series each consist of three models ranging from 100 MHz to 200 MHz, with two or four analog channels, the traditional Tektronix front-panel layout, serial triggering, protocol decode, USB plug-and-play PC connectivity, a seven inch widescreen bright TFT display, and a three-year warranty. The MSO2000 models also include 16 digital channels, providing up to 20 time-correlated channels to debug both analog and digital data. All models contain 1 million points of record length on each channel and a 1 GSps sampling rate on all channels, ensuring at least 5x over-sampling of the signal. Additionally, the new models provide 5000 waveforms per second capture rate to aid discovery of transient events.
The new FilterVu variable low-pass filter provides a powerful tool to block unwanted noise from signals, while still capturing glitches and other signal details up to the full bandwidth of the oscilloscope. The new scopes simultaneously display the filtered waveform and high frequency details up to their full bandwidth.
The new units also include the Wave Inspector search engine on all analog and digital channels, a set of easy-to-use tools that make simple and efficient work of finding events of interest in long records. Wave Inspector also provides the ability to automatically search through an acquisition and mark all occurrences of a user-specified event, and then navigate between the marks.
All models include a USB host port on the front of the instrument and USB device port on the rear. The front USB port supports a USB Flash drive, while the rear port is USBTMC compatible, which enables communication and control via a PC. The rear port is also PictBridge certified for printing to PictBridge certified printers.
