Introduction
Introducing the new MultiScope application
Need more than four simultaneous oscilloscope channels? Ever placed two oscilloscopes
together to see eight channels simultaneously? The Keysight Technologies, Inc. N8834A
MultiScope application enables Infiniium and InfiniiVision real-time oscilloscope users to
bring multiple oscilloscopes together for measurement on a single timebase. Capture, view,
and analyze up to 40 time-correlated oscilloscope channels. If your need for more than four
simultaneous channels goes away, each oscilloscope can be used independently and then
brought back together when there are future needs for more than four channel measurements.
Are you working on applications like power rails, high-speed multi-lane serial buses, optical
networking, or DDR memory systems? The N8834A MultiScope software allows connection
of 2 to 10 oscilloscopes to achieve up to 40 channels on a single timebase. Each oscilloscope
is daisy chained via cables and power splitters to the first oscilloscope, called the leader.
Automated calibration is available to allow channel correlation across frames down to less
than 1 ps. All oscilloscopes connect to a control PC via LAN or USB. The PC runs the Infiniium
application (user interface) and allows users to change settings on all oscilloscopes. The
Infiniium application on the PC shows all waveforms and measurements and offers analysis in
addition to controlling the oscilloscope settings. The leader can also work as the controller in
the absence of a control PC.

Features
–– Save costs by connecting up to 10 of your existing Infiniium
Series oscilloscopes to achieve 40 channel acquisitions in a
single timebase.
–– Data is presented to the user on a control PC or the leader
scope as if all oscilloscope channels existed on a single
frame.
–– Oscilloscopes can be separated and used independently
when four channels or fewer are needed.
–– Application supports multiple frames using the same family
of oscilloscopes (e.g. all V-Series scopes) or a heterogeneous
combination of different oscilloscope families (e.g. one 9000
Series and one S-Series). Time-correlation precision depends
on which frames are connected together.
Increase your productivity and efficiency
The N8834A MultiScope software works well with the new PChosted mode, which allows you to see live signals acquired from
the oscilloscopes on a PC installed with the N8900A Infiniium
Offline oscilloscope analysis software. Users can test lanes on
the MultiScope from the comfort of their own workbench. Users
can remotely login to the MultiScope application from the PC and
observe live traffic. The Infiniium Offline oscilloscope analysis
software application allows users to save the setup and waveform
files in a composite format (.osc) to be analyzed offline on the PC,
freeing up the MultiScope connection for others.
Analyze data on PC. User can either connect to live data for online
analysis via hosted mode or save the setup file to be viewed offline via
offline mode.

MultiScope Software Architecture
Control PC
The leader and the followers
The N8834A MultiScope application runs on a Windows 7 PC.
All the scopes are connected to the control PC via LAN or USB.
A control PC must be used if InfiniiVision scopes exist in the
multiscope configuration.
–– PC supports both hosted/online and offline analysis.
–– Scope front panels are disabled during MultiScope operation.
MultiScope is controlled by a PC installed with the N8900A
Infiniium Offline analysis software or the leader scope in the
absence of a PC.
–– Display up to 16 grids per window, up to 8 windows.
–– Full support of all measurements, functions, and analysis on
all channels.
–– Test at the comfort of your workbench.
The leader oscilloscope connects to the control PC via LAN or
USB or can act as the controller in the absence of the PC. The
one leader oscilloscope can connect two to nine followers. The
connection between oscilloscopes is daisy chained with cables
and splitters.
–– Support edge or glitch trigger on leader (other triggering
modes (including InfiniiScan) are not supported).
–– One-time deskew eliminates frame-to-frame skew created by
trigger daisy chain connection.
–– Achieve inter-scope intrinsic jitter of 150 fs with precision
calibration on the 90000 Q-Series and Z-Series Infiniium
oscilloscopes.
–– 10-MHz reference clock aligns sample for deep memory
synchronization.
Daisy chained connection with power splitter and BNC cables.
View of 6 channels and 3 eye diagrams on a single window with 8 grids.
Leader scope is used to control and display multichannel waveforms.

Calibration Methods
There are three calibration methods available with the N8834A
MultiScope software. Each calibration method provides a
different level of channel-to-channel skew value. Manual
calibration is available for users who are interested in viewing
multi-channel signals but not concerned about the skew factor
across channels. External trigger helps users achieve 100 ps
channel-to-channel skew. The most accurate measurements can
be achieved with the drift correction method with skew in the
range of 200 fs.
1. Manual
Manual calibration requires no cabling and users can achieve
skew correction by manually dialing in the right skew values
between the channels. InfiniiVision scopes supports only manual
calibration.
2. Basic
The trigger out process provides the most basic level of interoscilloscope time synchronization. This process connects the
trigger output signal (Trig Out) from the leader oscilloscope
through each follower oscilloscope (Aux Trig) in a daisy chain
configuration. The followers are each armed in descending order
from furthest from the leader (F{N}) to nearest to the leader (F{1}).
The leader’s trigger is armed last. Once the leader triggers, each
follower will trigger in turn, down through the chain.
3. Precision
The horizontal position of channels within different oscilloscope
frames can drift with temperature (inter-oscilloscope drift). The
drift correction synchronization process corrects for this drift by
monitoring the inter-oscilloscope drift on a separate, dedicated
synchronization channel. The idea is that any “time corrections”
that keep the synchronization channels aligned will also keep
the signals aligned. Precision calibration will consume one of the
channels on each oscilloscope and is only available on 90000 X-,
90000 Q-, V-Series, and Z-Series oscilloscopes. On the Infiniium
90000 X- and V-Series, a maximum of two oscilloscopes can
be connected to perform precision calibration. A sync port is
available for precision calibration on 90000 Q- and Z-Series.
