Uncompromising Analysis Capability
Many modular users have been using digitizer hardware with software that simulates
an oscilloscope for test and troubleshoot implementation. The limitations of this
configuration are often overlooked, but they can cause signification problems. When a
instrument says it has a high waveform update rate, people usually expect it to have a
higher probability of catching random and infrequent glitches, but this isn’t the case for
those instruments. In addition, common measurements like waveform averaging and
advanced waveform triggers are not available.
Keysight is currently the only vendor that delivers oscilloscope hardware in a PXI
modular package. Keysight’s M924XA Series PXIe oscilloscopes begin with basic digitizer
hardware, but then they add measurement tools directly into the hardware of the PXI
card.
The InfiniiVision PXIe modular oscilloscopes require minimum support from a central
processing unit (CPU), as most of their core operations are handled by the MegaZoom
IV smart memory ASIC, which is Keysight proprietary technology. MegaZoom includes
hardware serial decoders and hardware mask/limit testing capability; plots analog and
digital data directly to the display; supports GUI operation; and integrates additional
instruments like a WaveGen function/arbitrary waveform generator.

Industry-exclusive Zone Touch Trigger Makes Triggering Simple
Zone touch triggering eliminates the complexity of setting up advanced triggers. If you
have a touch-enabled display on your controller, you can trigger on events by simply
drawing a box with your finger on the display of the signal you want to isolate. Keysight
pioneered the zone touch trigger, which allows easy capture of difficult-to-define trigger
events.
The M924XA Series’ high, uncompromised update rate increases your chance of seeing
random and infrequent signal anomalies, and zone touch trigger helps you isolate the
signals. Now your testing can be faster and more thorough.
Other touch-based operation
Just like Keysight’s touch-enabled InfiniiVision benchtop oscilloscopes (3000T, 4000
and 6000 X-Series), the M924XA Series also uses touch capability to interact with signal
display. In addition to zone touch trigger, these oscilloscopes also let you move the
waveform up/down; adjust the time offset and zoom; and define one of the two touch
zone triggers. All that is required is a touch-enabled display connected to your modular
scope.

Probing Solutions for PXI Modular
Keysight has probing solutions for the most challenging test
applications. The M924XA Series PXIe modular oscilloscopes
support standard 50 Ω or 1 MΩ connections. They also support a
wide range of passive and active probes.
M924XA Series oscilloscopes require the M9240A PXIe AutoProbe
power module to use Keysight active probes. The M9240A
provides power and the communication circuit required for proper
operation of the active probes. One M9240A will supply the power
and connection for up to four probes when two oscilloscope
modules are installed on either side of the M9240A module.

Additional Software for Added Functionality
M9240AWGA WaveGen 20 MHz function/arbitrary waveform generator
The M924XA Series oscilloscopes offer
a 20-MHz built-in function/arbitrary
waveform generator. The WaveGen
provides standard stimulus output
waveforms to your device under test
as well as user-definable frequencies,
amplitudes, offset and pulse widths
and arbitrary waveform capability. The
WaveGen output is routed to a MMCX
connector on the front panel of the
oscilloscope.
Use the built-in waveform editor to create
custom waveforms to output on the
oscilloscope’s WaveGen. It is also possible
to capture a known good or ‘golden’
waveform on a scope channel and then
save that to the ARB so you can generate
it to stimulate your system under test.
M9240FRAA frequency response analyzer
Frequency response analysis is a critical
measurement to characterize the stability
of feedback networks and switch-mode
power supplies. This capability is achieved
with a gain and phase measurement
versus frequency (Bode plot). By using the
waveform generator output to stimulate
your design and probing the input and
output signals on channels 1 and 2, the
oscilloscope provides a clear report on the
gain and phase operation of the system.

M9240MSKA mask limit testing
With the mask limit testing measurement
application, you can quickly test more than
200,000 waveforms per second to a known
good waveform with quick go/no-go test
results, saving you valuable test time while
providing you with more confidence in
test results. Test your signals to specified
standards, and uncover unexpected signal
anomalies.
Mask testing on other oscilloscopes is
usually based on software-intensive
processing technology, which tends
to be slow. Keysight’s M924XA Series
oscilloscopes’ mask test option is based
on hardware-based technology. This
means M924XA Series oscilloscopes can
perform more than 200,000 real-time
waveform pass/fail tests per second. This
provides testing throughput that is orders
of magnitude faster than what is available
on other oscilloscope mask test solutions,
making valid pass/fail statistics almost
instantly.
M9240VIDA enhanced video/TV application package
The M924XA Series oscilloscopes
support a video IRE display grid, as well
as cursors measurements performed in
video IRE units for the NTSC and PAL
standards. This new capability is standard
on M924XA Series oscilloscopes. The
M9240VIDA software provides an array
of additional HDTV triggering standards.
The additional triggering options provided
by the M9240VIDA software speed debug
and characterization for engineers working
on HDTV video applications.

an increasing number of constraints
in the development of high-efficiency,
low-cost power supplies. The power
analysis application provides clear and
consistent reporting on the operation of
key operation parameters of your power
supply design.

power, reactive power, power factor,
crest factor (V and I), phase angle
–– Current harmonics (based on IEC
61000-3-2 up to the 40th harmonic)
–– Inrush current
Switching measurements
–– Rds-on and Vce-sat
–– Switching loss (power and energy)
–– Slew rate (dv/dt and di/dt)
–– Modulation (duty cycle, pulse-width,
period, frequency, versus time plot,
etc.)
Output measurements
–– Output ripple
–– Turn-on/turn-off time
–– Transient response time
–– Efficiency
Frequency response measurements
–– Power supply rejection ratio (PSRR)
–– Control loop response – Bode
M9240NFCA NFC triggering
Testing NFC-enabled devices is essential during the design validation and manufacturing
test phases to ensure quality and reliability of data transmission. This is especially
important when you consider that the data being transferred/exchanged between NFCenabled devices is often secured financial transactions. The M9240NFCA NFC trigger
application enables easy configuration to capture the signals of interest for NFC-A,
NFC-B and NFC-F messages.

Decodes
M9240EBMA embedded serial triggering and analysis (I²C)
The I²C serial decode software option for M924XA Series oscilloscopes displays
responsive, time-aligned, on-screen decode of Inter-Integrated Circuit (I²C) serial
communication. Because this capability is hardware-based, it provides the fastest
throughput solution for triggering on and analyzing I²C serial buses found in a wide
variety of embedded designs. You can easily isolate serial packets to find sources of
errors due to hardware- or software-related problems. Sometimes it may be necessary
to correlate data from one serial bus to another. Keysight’s M924XA Series oscilloscopes
can decode two serial buses simultaneously using hardware-based decoding.
M9240CMPA computer serial trigger/analysis
(RS232/422/485/UART)
The RS232/422/485/UART serial triggering and decode option for M924XA Series
oscilloscopes displays responsive, time-aligned, on-screen decode of RS-232/422/485
and other UART serial buses. It provides triggering capabilities on specified transmit or
receive values, as well as on parity errors. Trigger on and acquire RS-232/422/485/UART
signals using either oscilloscope or logic channels. Hardware-based decode means
the scope stays responsive and fast when decode is turned on. Real-time counters
continually count transmit and receive frames and errors.
M9240ATOA automotive serial triggering and analysis
(CAN, CAN-dbc, CAN FD, LIN)
The automotive serial triggering and analysis (CAN, LIN) option for M924XA Series
oscilloscopes allows you to trigger on either standard or extended CAN message IDs,
including the message ID of a remote transfer request frame. It supports triggering on
a data frame and allows you to specify message IDs, data and data length for filtering
messages of interest. Triggering on active error frames is also supported. In addition,
it supports triggering on LIN frame IDs and data and includes color-coded parity and
check sums errors. You can easily isolate serial packets to find sources of errors due to
hardware- or software-related problems. Sometimes it may be necessary to correlate
data from one serial bus to another.

M9240SNSA SENT (single edge nibble transmission) trigger and
analysis
The SENT (single edge nibble transmission) is a point-to-point serial bus that interfaces
sensors to ECUs and is used primarily in automotive applications. Keysight’s M9240SNSA
SENT software option for the M924XA Series oscilloscopes provides decoding of fast
and slow channel serial data and also offers extensive triggering selections, including the
ability to trigger on various error conditions that can accelerate efficiency in debugging
this bus.
Keysight’s M924XA Series oscilloscopes can display captured data from multiple buses
in a time-interleaved “lister” display. Sometimes it may be necessary to correlate data
from one serial bus to another, such as CAN to SENT.
M9240CXPA CXPI trigger and decode
CXPI (clock extension peripheral interface) is the next-generation automotive
communication protocol intended to reduce the number and weight of wiring harnesses
by making multiplexing possible even in advanced, multifunction HMI (human machine
interface) automotive systems. In many cases, CXPI is an alternative serial bus used in
place of many of today’s LIN serial bus applications for automotive body control.
Keysight’s M9240CXPA CXPI software for M924XA Series oscilloscopes provides
decoding of standard and long CXPI frames and also offers extensive triggering
selections, including the ability to trigger on various error conditions that can accelerate
the engineer’s efficiency in debugging this bus.
Keysight’s M924XA Series oscilloscopes can display captured data from multiple buses
in a time-interleaved “lister” display. This allows correlation of data being passed through
gateways, such as CAN to CXPI.
M9240AROA MIL-STD 1553 and ARINC 429 aerial triggering and
analysis
The MIL-STD 1553 serial bus is primarily used to interconnect avionics equipment in
military aircrafts. This bus is based on tri-level signaling (high, low and idle) and requires
dual-threshold triggering, which the M924XA PXIe modular oscilloscopes support. This
bus is also implemented as a redundant multi-lane bus (dual-bus analysis), which is also
supported.
The ARINC 429 serial bus is used to interconnect avionics equipment in civilian aircrafts.
This bus is also based on tri-level signaling (high, low and null) and requires dualthreshold triggering. Since ARINC 429 is a point-to-point bus, multi-lane analysis is also
required to capture both send and receive data.
M9240NRZA user-definable Manchester and NRZ trigger and
analysis
Keysight’s Manchester and NRZ decode and trigger software supports user-defined
protocols, offering flexibility and preventing the need to define multiple specific protocol
decoding and triggering. This trigger and decode software application is geared toward
automotive customers, who commonly use Manchester and NRZ encoded buses (ex:
Profibus PA, DALI, PSI5, etc.).

license that enables the software for as long as the oscilloscope is installed where the
software license is located. Controller-based licensing enables licensed feature for all
M924XA oscilloscopes in the system.
There are other alternatives:
1. Fixed permanent license (described above)
2. Transportable permanent license – Can move the software license as needed
3. Fixed time-based license – Enabled license for a limited time period
4. Transportable time-based – Can move the software license as need for a limited
time period
Step 3. Choose your probes
The M924XA Series oscilloscopes do not include any probes.
–– Option 808 – Add N2843A 500 MHz passive probes
Other probes are supported but must be purchased as separate products. Please
note that active probes (current, differential, extreme environment probes) require
the purchase of the M924XA AutoProbe power module. This module supports the
connection, power and communication of the AutoProbe interface. A single M924XA
AutoProbe power module will supply the connections and power for two modular
oscilloscopes installed in adjacent module slots.
