Introduction
The InfiniiMax Ultra series probe amplifiers provide high bandwidth (maximum up
to 25 GHz) and an RC input impedance profile for extremely low mid-band loading,
which is necessary to address modern high-speed probing requirements.
You can use these amplifiers to probe differential as well as single-ended signals.
These amplifiers support a wide variety of flexible connectivity solutions, covering
today's emerging signaling standards such as DDR5/LPDDR5 and other
high-speed signal debug and validation test needs.
With an extensive range of supported probe heads and accessories, these probe
amplifiers cater to most of the probing situations including harder to probe small
geometry target devices and extreme environment testing.

Probe Amplifier Component Description/Usage
Output Connector The MX0020A/21A/22A/24A/25A probe amplifiers have the
Keysight AutoProbe II (3.5 mm) interface that allow these to
connect to a compatible Keysight oscilloscope (see page 14).
The oscilloscope’s AutoProbe interface provides the probe power,
probe offset, and auto configuration of probe type and attenuation
setting on connection.

Probe Response Button Press this button to switch between the following two probe
response options available for the MX0020A/21A/22A/24A/25A
probe amplifiers.
•True View (Vout/Vin)
•Source Estimate (Vout/Vsource assuming a 25 Wsource
impedance)
Each probe response option has an associated LED on the probe
amplifier. The LED for the currently active probe response option
lights up green.
(See page 139 to get details on these probe response options.)
Menu Button Press this button to bring up the Infiniium GUI’s Probe
Configuration dialog box on the oscilloscope. Use this dialog box
to configure probe settings (see page 127).
Channel Identification Rings When multiple probes are connected to the oscilloscope, use the
channel identification rings to associate the channel inputs with
each probe. Place one colored ring near the probe’s output
connector and place an identical color ring near the probe head
connector.
Polarity Markings (A and B) Polarity markings to indicate the A (+) and B (-) inputs of the probe
amplifier.
Probe Head Connector Use this connector to connect your probe amplifier to one of the
supported probe heads (see page 16).
Ground Connection Allows you to connect the DUT ground to the probe amplifier
ground using a ground lead wire.
This is needed if the DUT is not grounded to the oscilloscope via
the AC mains ground (see page 158).

InfiniiMax Ultra Series Probe Amplifiers Key Features
Probe Response
Options
The MX0020A/21A/22A/24A/25A probe amplifiers support the following two
probe response options:
InfiniiMode
Capable
All InfiniiMax Ultra series probe amplifiers are InfiniiMode capable. An InfiniiMode
capable probe amplifier when used with an InfiniiMode capable probe head allows
you to make single-ended A, single-ended B, differential as well as
common-mode measurements using the same probing setup. You do not need to
reconnect the probe leads or change connections for these different
measurements.
See page 150 to know more about InfiniiMode and how to set up the probe
hardware and software to make InfiniiMode measurements.
Yielding Accurate
Measurements
These probe amplifiers have built-in probe specific s-parameter correction filter to
ensure a flat frequency response. This unique s-parameter of the probe amplifier is
used with the s-parameters of various supported probe heads to further flatten the
magnitude and phase response of the probe for high accuracy measurements.
Each probe head has different s-parameters stored in the oscilloscope’s firmware.
On selecting the probe head in the oscilloscope’s software, the appropriate s-
parameters for the probe head are used in conjunction with the probe amplifier’s
s-parameters to compute the overall probe correction for your measurement case.
“RC" Input
Impedance
Architecture
The RC architecture of these probe amplifiers make these suitable for probing
buses that transition to a “high Z” state or for probing signals with high
impedance.
See Also: Demystifying RCRC and RC probes Application Note
Three Input
Attenuation
Ranges
These probe amplifiers support the following three flexible input dynamic ranges.
• 600 mVpp @ 1:1
True View Vout/Vin correction to show the voltage at the tip of the probe as loaded by the
probe.
Source Estimate Vout/Vsource correction to show an estimate of the voltage at the probe point as if
the probe is not there (assumes a 25 Wsource impedance).
- VIn represents a signal with the probe’s effect included (the voltage at the probe’s tip).
- Vsource represents a signal at the probe point before the probe is connected.
- Vout represents the signal as passed through the probe.
See page 139 to know how to set up and use these options.

MX0020A/21A/22A/24A/25A Probe Amplifiers - Overview 1
InfiniiMax Ultra Series Probe Amplifiers & Probe Heads User’s Guide 13
• 2.5 Vpp @ 4:1
• 5 Vpp @ 8:1
The input range is automatically configured depending on the vertical scale of the
oscilloscope.
High Bandwidth
Probing
Requirements
These probe amplifiers efficiently fulfill the probing bandwidth requirements
between 10-25 GHz. For instance, MX0025A is best suited for serial links
operating up to 12 Gbps that require the probe bandwidth up to 25 GHz.
Applicable
System
Bandwidth
For any combination of a probe head with these probe amplifiers, the applicable
system bandwidth is the lesser of the supported bandwidths of the probe head or
the probe amplifier. For instance, the MX0025A supports 25 GHz bandwidth.
Therefore, if, for example, you use it with the MX0106A probe head, which
supports a 23 GHz bandwidth, then this combination would produce a system
with a 23 GHz bandwidth.

10. N5425B ZIF Probe Head with Long Wire ZIF Tips (refer to 1168/9B-Series Probes user’s guide)
•The long-wired ZIF tips connection is ideal
for variable pitch targets, including larger
pitches
•Ideal for probing multiple signals in tight
spaces such as DDR memory
•ZIFs can be installed at multiple locations
on your DUT
•ZIF feature allows connection without
compressing the delicate wires which
cannot support this compression
•Recommended for DDR4, DDR5, LPDDR4,
MIPI D-Phy 2.0 and C-Phy 2.0

a The bandwidth listed in this table is the maximum bandwidth supported by each probe head. For any combination of a probe head with a probe
amplifier, the applicable bandwidth is the lesser of the supported bandwidths of the probe head or the probe amplifier. For example, using the
MX0025A, which supports a 25 GHz bandwidth, with a MX0106A, which supports a 23 GHz bandwidth, would produce a system with a 23 GHz
bandwidth.
