Symbolic Bus Formats Simplify Identifying System States and Setting up Bus Triggers.
10 ms Duration Capture of Synchronous High-speed and Low-speed Signals at 25 GS/s.
Bus Decoding and Triggering (MSO70000 only)
Verifying your system operation often requires the ability to see specific
system states on a key bus such as the DDR SDRAM interface. The
MSO70000 includes parallel and low-speed serial bus decoding that
provides deeper insight into the system’s behavior. Using the bus triggering
capability of the MSO70000 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.
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
DPO/DSA70000B Series as well as the 16 logic channels of the MSO70000
Series. Optional memory depths up to 125 MS (Option 10XL) on the 4, 6,
and 8 GHz models and 250 MS (Option 20XL) on the 12.5, 16, and 20 GHz
models are available.
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 MSO70000 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 DPO/DSA70000B and
MSO70000 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 comes standard on the DSA70000B Series and is
available on DPO70000B and MSO70000 models as Option PTH. Option
PTH and the DSA70000B Series cover serial standards up to 3.125 Gb/s.
For higher bit rate standards like USB 3.0, Option PTU on the DPO70000B
Series and Option STU on the DSA70000B Series extend 8b10b triggering
and decode to 5 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 stream and is standard on the DSA70000B
instruments, or is included as part of Option PTH on the DPO70000B and
MSO70000 models.
