More speed and lowest noise: Tektronix’s 6 Series MSOs

20 July 2018

Tektronix have introduced the 6 Series MSO mixed signal oscilloscope, which extends the performance threshold of mid-range oscilloscopes to 8 GHz and delivers a 25 GS/s sample rate simultaneously on all 4 channels.

For this class of oscilloscope, this is in fact an industry first: one that accommodates the needs of designers working on faster, more complex embedded systems designs. With 25 GS/s sample rate on all channels, designers can accurately now view up to four high speed signals at one time.

For example, a DDR3 clock and three DDR3 data channels can be viewed and analysed simultaneously; this decreases the time it takes to fully characterise a design with an instrument that shares sampling systems between channels.

The new 6 Series MSO also boosts measurement confidence with its low noise inputs, especially at the highest sensitivity settings where it matters most. For example, modern embedded designs require clean, precisely controlled DC power supplies to feed ASIC and FPGA devices. For such applications, the 6 Series MSO enables designers to measure DC power rails with more resolution and accuracy, reducing the time it takes to understand high frequency influencers on power rails in a design.

Based on the same breakthrough platform as the popular 5 Series MSO, the 6 Series MSO provides easy upgradeability for long term investment protection. Introduced last year to numerous awards from across the industry, the 5 Series MSO was the result of a clean sheet design.

The product features a host of innovations that carry over to the 6 Series MSO, which includes a remarkably intuitive user interface, a capacitive pinch-zoom-swipe 15.6-inch touchscreen, innovative FlexChannel inputs, a 12-bit ADC that can deliver up to 16 bits of vertical resolution, a completely new industrial design, and optional Windows 10 operating system.

“The trend toward higher performance in embedded systems is now in full swing with no end in sight,” said Chris Witt, general manager at Time Domain Business Unit, Tektronix. “Our customers developing these systems need more bandwidth and lower-noise inputs, but they also still want the usability, convenient probing and compact packaging of midrange scopes. With the 6 Series MSO we’re delivering a compelling combination of class-leading performance and usability that will boost productivity and shorten time to market.”

New levels of signal detail

To meet the need for more insight on faster signals, the 6 Series MSO incorporates a new low-noise preamplifier ASIC, the TEK061, that dramatically lowers noise, especially on signals that are in the hundreds of millivolts peak-to-peak. With its 25 GS/s sample rate on four channels, the instrument delivers 16-bit resolution at 200 MHz when using the High Res mode. This means that not only can designers see the interfering signals on their power rail, but they can measure them with a level of accuracy, that until now has not been possible on a scope.

Like the 5 Series MSO, the 6 Series MSO is highly upgradeable and is available with a built-in arbitrary/function generator, a free DVM and trigger frequency counter with product registration, protocol options, and offers a choice of operating system. Also, like the 5 Series MSO, adding a TLP058 logic probe turns any of the instrument’s four FlexChannel inputs into eight digital inputs, providing the most flexible MSO configurations available. The 6 Series MSO also has upgradeable bandwidth, starting at 1 GHz and extending up to 8 GHz with a simple licence upgrade.

Expanded decode, analysis

For its next-generation platforms, Tektronix is committed to adding capabilities to meet rapidly evolving market requirements, providing engineers with the confidence that they are making the right choice when they select these scopes. Since the launch of the 5 Series MSO, Tektronix has added the following capabilities that will be available on both platforms:

- Options for decode and trigger support for CAN FD, MIL-STD-1553, ARINC429 and SENT bus

- Options for serial compliance testing for Automotive Ethernet and USB 2.0

- An advanced power analysis option with two rounds of free enhancements

- New, free capabilities including FastFrame segmented memory and enhanced autoset

- In conjunction with the 6 Series MSO launch, Tektronix is also releasing Visual Trigger capability and a new option for SPMI serial trigger, decode and search, a MIPI power management bus

New high performance probe options

For easier connection to fast signals, Tektronix is also launching a series of new higher performance probes well suited to the performance levels of the 6 Series MSO. The TDP7700 is a series of TriMode probes with bandwidths of 4, 6 or 8 GHz. TriMode probes enable engineers to make the single-ended, differential, and common mode signal measurements required for high-speed bus analysis, without moving or changing probes.

These probes use the TekFlex connector technology: this places active buffers at the probe tip for the best signal fidelity, while limiting mechanical stress on tiny test points; it also supports a variety of connectivity methods to the device under test (including solder-in tips, direct connection and handheld browsing).

Additionally, the TAP4000 and TDP4000 probes extend the range of Tektronix’s popular active, single-ended and differential probes, respectively, and now support up to 4 GHz bandwidth.
