Oscilloscope Experience Redefined:
Experience the Integration (Continued)
Mixed signal oscilloscope (MSO): Integrated
16 digital channels
With an additional 16 integrated digital channels, you now have
up to 20 channels of time-correlated triggering, acquisition and
viewing on the same instrument. This is especially important
in today’s embedded designs with sophisticated digital control
circuitry. Unlike other oscilloscopes in this class, you can buy a
2- or 4-channel DSO and enable the 16 digital channels already in
the instrument at any time to make it an MSO. (DSOXPERFMSO)
Figure 19. Digital channels are captured and displayed time-correlated
with analog channels in MSOs or upgraded DSOs.
Serial protocol analysis: Hardware-based serial
protocol decode and triggering
Keysight InfiniiVision Series, including the new 4000 X-Series,
are the only oscilloscopes to use hardware-based serial
protocol decoding. Other vendors’ oscilloscopes use software
post-processing techniques to decode serial packets⁄ frames,
and therefore have slow waveform and decode capture rates and
could miss critical events and errors due to a long dead-time.
Faster decoding with hardware-based technology enhances the
probability of capturing infrequent serial communication errors.
After capturing serial bus communication, you can easily
perform a search operation based on specific criteria and then
quickly navigate to bytes/frames of serial data that satisfy that
search criteria. The 4000 X-Series can decode two serial buses
simultaneously using hardware-based decoding, and display the
captured data in a time interleaved “lister”display.

display.
Serial protocol decoding can be used simultaneously with
segmented memory and zone touch triggering.
The 4000 X-Series has: SENT, I2C, SPI, USB 2.0, RS232/UART,
CAN, CAN FD, LIN, FlexRay, CXPI, MIL-STD 1553, ARINC 429, I2S,
user-definable Manchester, user-definable NRZ, and USB PD.
