MultiScope Application

For Infiniium Oscilloscopes

Product Overview

Today’s oscilloscopes generally come with 2 or 4 analog channels. Some, like our Infiniium EXR and MXR Series, even come with 8 analog channels. But what if you need more? 12, 16, or more in one time coherent system? You could turn to digital channels – most oscilloscopes offer 16 of those. But you are limited to 1 bit of resolution, and can’t see any details of your waveform. You can also leverage the trigger-in and trigger-out BNCs on most oscilloscopes, to daisy chain them together. That way when one scope triggers, they all trigger. But this can create significant delay between frames, and all the channels in your test system aren’t presented on a single screen.

The optimal solution here is Keysight’s Multiscope software, standard on all Infiniium oscilloscopes. With the purchase of a cabling kit, or using your own hardware you may have in the lab, multiple Infiniium oscilloscopes can be synchronized together to present up to 40 channels across 10 oscilloscopes on one user interface with minimal jitter from frame to frame.

This is done with a one-time synchronization step that removes the delay induced from the trigger in and trigger out connection and cabling, allowing for frame to frame jitter in the range of a few picoseconds, or less with the precision cal available on our higher performance models.

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 Infiniium Offline 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 oscilloscope can also work as the controller in the absence of a control PC.

Features

  • Standard feature on all Infiniium oscilloscopes with software version 6.30 or greater – only need to purchase cabling kits and Infiniium Offline, if controlling from a PC instead of the leader oscilloscope.
  • 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 used independently when four channels or fewer are needed.
  • Application supports multiple frames using the same family of oscilloscopes (e.g. all UXRSeries scopes) or a heterogeneous combination of different oscilloscope families (e.g. one MXR-Series and one EXR-Series). Time-correlation precision depends on which frames are connected together.

MultiScope Software Architecture

Control PC

MultiScope is controlled by a PC installed with the Infiniium Offline analysis software, or the leader scope in the absence of a PC. Using a separate PC may be preferred from a usability standpoint, since this level of channel density may benefit from a higher resolution external display.

Infiniium gives you full flexibility on how channels are presented, allowing you to display up to 16 grids per window, up to 8 windows. There is full support of all measurements, functions, and analysis on all channels, letting you test at the comfort of your workbench.
