iCapture™ – One connection for analog and

digital (MSO70000DX Series)

The number of signals that must be verified can often make the

checkout of a design long and involved. By using the iCapture

digital-to-analog multiplexer feature, you can easily verify the

analog characteristics of any of the 16 signals connected to the

MSO70000DX Series digital channels without changing probes or

connections. Using iCapture, you can quickly view the analog

characteristics of any input channel. If the signal is working as

expected, relegate it to a digital-only view and continue testing

other lines.

Bus decoding and triggering

Verifying your system operation often requires the ability to see

specific system states on a key bus such as the DDR SDRAM

interface. The MSO/DPO70000DX Series includes parallel and

serial bus decoding that provides deeper insight into the system's

behavior. Using the bus triggering capability of the MSO/

DPO70000DX Series to isolate the exact state needed or find

invalid bus sequences is as easy as defining the bus and choosing

the bit pattern or symbolic word that describes the desired state. In

addition, serial bus decoding for 8b/10b encoded data, I2C, SPI,

RS-232/422/485/UART, USB, and MIPI DSI and CSI2 buses

enables you to identify where control and data packets begin and

end as well as identify subpacket components such as address,

data, CRC, etc.

Symbolic bus formats simplify identifying system states and

setting up bus triggers

Deep record length available on all

channels

Longer duration events such as power supply sequencing and

system status words can be analyzed without sacrificing timing

resolution using the long memory depths available on all four

analog channels in the DPO70000DX Series as well as the 16

logic channels of the MSO70000DX Series. Optional memory

depths up to 500 MS (4 channels)/1 GS (2 channels) with option

50XL are available.

10 ms duration capture of synchronous high-speed and low-

speed signals at 25 GS/s.

Power supplies can be a critical failure point in any system.

Careful testing of the power delivery system's power on sequence

can be time consuming. The MSO70000DX Series provides

independent logic thresholds for each logic channel enabling

multiple logic voltages to be set up and observed simultaneously

for quick verification of the system's power rails.

Protocol and serial pattern triggering

To verify serial architectures, the serial pattern triggering for NRZ

serial data streams with built-in clock recovery in the MSO/

DPO70000DX Series allows correlating events across physical

and link layers. The instruments can recover the clock signal,

identify transitions, and allow you to set the desired encoded

words for the serial pattern trigger to capture. This feature is

available on the MSO/DPO70000DX Series as Option ST6G. For

higher bit rate standards like USB 3.0, the 8b/10b serial pattern

trigger and decode covers data rates up to 6.25 Gb/s.

Pattern lock triggering adds an extra dimension to NRZ serial

pattern triggering by enabling the oscilloscope to take

synchronized acquisitions of a long serial test pattern with

outstanding time base accuracy. Pattern lock triggering can be

used to remove random jitter from long serial data patterns.

Effects of specific bit transitions can be investigated, and

averaging can be used with mask testing. Pattern lock triggering

supports up to 6.25 Gb/s NRZ serial data streams and is included

as part of Option ST6G on the MSO/DPO70000DX Series.

Visual Trigger – Find the signal of interest quickly

Finding the right cycle of a complex bus can require hours of

collecting and sorting through thousands of acquisitions for an

event of interest. Defining a trigger that isolates the desired event

speeds up debug and analysis efforts.
