Features:
• Optimized acquisition memory
• Capture up to 2000 successive
waveform segments
• Fast re-arm time
• Down to 250 ps time-tag resolution
• Segments include all analog and digital
channels of acquisition
• Segments include serial bus decoding

Mixed-signal and serial bus applications
Serial bus measurements are another
application area where segmented
memory acquisition is useful. You can
optimize the number of packetized
serial communication frames that
can be captured consecutively by
selectively ignoring (not digitizing)
unimportant idle time between frames.
As mentioned earlier, Agilent’ s
InfiniiVision Series oscilloscopes are
the only scopes on the market today
that not only can acquire segments
of up to four analog channels of
acquisition, but also can capture
time-correlated segments on digital
channels of acquisition (using an MSO
model), along with hardware-based
serial bus protocol decoding. The
segmented memory option on Agilent’s
InfiniiVision Series oscilloscopes is
compatible with all of the following
serial bus triggering and decoding
options:
Figure 3: Capturing 1000 consecutive decoded CAN frames using
segmented memory.
• I2C/SPI (N5423A or Option LSS)
• RS-232/UART (N5457 or Option 232)
• CAN/LIN (N5424A or Option AMS)
To illustrate how segmented memory
acquisition can enhance serial bus
measurements, we will examine a
mixed-signal automotive CAN bus
measurement application. Figure 3
shows a CAN bus measurement with
the scope set up to trigger on every
start-of-frame (SOF) condition. Using
this triggering condition with the
segmented memory acquisition mode
turned on, the scope easily captures
1000 consecutive CAN frames for a
total acquisition time of 2.4 seconds.
After acquiring the 1000 segments/
CAN frames, we can easily scroll
through all frames individually to look
for any anomalies or errors. In addition,
we can easily make latency timing
measurements between frames using
the segmented memory’s time-tagging.
Also note that in this measurement
example, eight time-correlated digital
channels were acquired along with the
analog CAN signal and decoding.
