Mixed-signal scopes offer 'intuitive' control

Tektronix Inc. has announced the availability of the MSO4000 family of mixed-signal oscilloscopes (MSO). This new product family combines three capabilities—an advanced real-time oscilloscope, a logic analyser and the Wave Inspector waveform search engine—in one small and lightweight portable device for embedded design and debug. MSO4000 oscilloscopes provide a familiar front-panel and a clear display, letting the engineer control everything intuitively, but with only a fraction of the size and weight of other MSOs, the company said.

Embedded design debugging
Debugging an embedded design often requires viewing analogue signal phenomena and the interaction of digital control signals. In this mixed-signal environment, engineers cannot accurately predict the type of problems that will be uncovered during development. They need a test instrument with the ability to acquire both analogue and digital signals and display them time-correlated on a single display. Tektronix said its new MSO4000 series combines leading oscilloscope and basic logic analyser capabilities so engineers can conveniently visualise and correlate analogue and digital signals on a single instrument.

"Embedded system designers are often working with both analogue and digital signals in their designs and need powerful yet easy-to-use test tools for both," said Bob Bluhm, VP and general manager of the value scope product line at Tektronix. "The new MSO4000 provides fully featured analogue and digital channels, long-record length on all channels, the most powerful productivity tools including the largest display, Wave Inspector, and an industry-best price/performance."

The MSO4000 family consists of four models ranging from 350MHz to 1GHz, with two or four analogue channels and 16 digital channels to provide up to 20 time-correlated channels. The MSO4032 and MSO4034 provide bandwidth of 350MHz on two and four analogue channels, respectively. The MSO4054 provides 500MHz bandwidth across four analogue channels and the MSO4104 offers 1GHz bandwidth on the four analogue channels. The MSO4104 provides 5GSps sampling on all channels while the other models provide 2.5GSps on all channels. All models come standard with 10M record length on all analogue and digital channels.

Digital acquisition modes
The MSO4000 provides two methods for capturing digital waveform data. The main digital acquisition mode captures 10M points at 500MSps (2ns resolution). The MSO4000 also provides MagniVu ultra high resolution signal acquisition technology that acquires 10,000 points at up to 16.5GSps (60.6ps resolution). Both the main and MagniVu waveforms are acquired on every trigger and can be viewed at any time, running or stopped. MagniVu provides greater than eight times faster timing resolution than any other MSO on the market, instilling confidence when making critical timing measurements on digital channels.

The MSO4000 offers the Wave Inspector on all analogue and digital channels, a set of easy-to-use tools for discovery and efficient viewing, navigating and analysing waveform data. Managing up to 20 channels, each with 10M record length, has been dramatically simplified through automated waveform pan and zoom, user definable markers and intelligent search and find modes. All MSO4000 models provide a 10.4-inch, XGA colour display, the largest and highest resolution display in its class, the company said. At only 5.4 inches deep, the MSO4000 is the shallowest on the market, the company said, requiring less bench space than competing products. It weighs only 11lbs for easy portability.

The MSO4000 combines leading specifications, familiar operation, innovative troubleshooting capabilities and comprehensive support for monitoring, triggering and decoding parallel buses and the most common serial buses used in embedded design.

Digital probe
Along with the new MSO4000 oscilloscopes, Tektronix is introducing the P6516 digital probe. This probe design offers two eight channel pods that can each probe parts up to 2.438m apart, facilitating the reach to multiple areas on a board with a single probe. Colour-coding of the leads correlates the probe tips to the signal trace on the display. The P6516 probe leads do not get tangled, making connecting to the device under test simple.

U.S. MSRP for the MSO4000 range from Rs.3.84 lakh ($8,700) for the MSO4032 model to Rs.7.59 lakh ($17,200) for the MSO4104 model. One P6516 probe is included with each MSO4000 model purchased. All MSO4000 models are available for purchase and delivery.
