Oscilloscope Security

Teledyne LeCroy's products reflect our mission to go beyond the limits of common industry constraints. At Teledyne LeCroy, we are also committed to strict adherence to oscilloscope security best practices by us as the provider, and urge your adoption as the user of our products.

Common Issues and Concerns

Adhering to oscilloscope security best practices mitigates common security concerns:

  • Teledyne LeCroy demonstration oscilloscopes are protected against viruses in order to protect customer information networks during evaluations.
  • Manufacturing and testing of Teledyne LeCroy oscilloscopes are done in a secure network environment. We employ scanning procedures using current virus definitions during production, to ensure a clean build environment. A signed certificate is included in the box prior to shipment.
  • Oscilloscopes returned to Teledyne LeCroy for repair, calibration, or updates are also scanned non-invasively on receipt and prior to customer return. A signed certificate to this effect is again provided for added peace of mind.
  • Reconditioned instruments are treated the same as original manufactured or serviced from a software perspective – each is made fully safe, secure, and updated prior to resale.
Teledyne LeCroy actively participates in Microsoft Service Pack betas, and also tests critical updates as they are made available. In the very unlikely event an update adversely affects the performance of your Oscilloscope, refer to this page for updated information and potential workarounds.

Windows Operating System Versions

Most legacy and currently released Teledyne LeCroy Oscilloscopes are built on versions of the Windows operating system. Windows provides easy access to peripheral hardware, third-party software, and familiar user interfaces to supplement the instrument's primary design purpose: capture and analysis of waveforms.

Note: These oscilloscope security practices are designed to help maintain the highest level of security on your Teledyne LeCroy instrument. We further recommend users leverage practices and general recommendations at www.microsoft.com.

Antivirus Software

Every new Teledyne LeCroy Windows-based oscilloscope includes free installation media for an industry-leading Antivirus software trial. We strongly advise that all oscilloscopes be fully-equipped with antivirus software and updated definitions before any and every network connection is made.

Oscilloscopes equipped with Windows XP Pro SP2, or later, detect the installed anti-virus software and reports when antivirus definitions are outdated.

Recommendations For You

While this process ensures you receiving your instrument without viruses, it does not necessarily protect your instrument from a virus once connected to your network.

You should take precautions when connecting a Teledyne LeCroy instrument to your network including:

  • Install antivirus software on your instrument.
    You may wish to check your IT department first to see if they have a preferred Anti-Virus tool.
  • Do not install multiple Anti-Virus programs on one instrument, and avoid installing one, un-installing it, and then installing a different Anti-Virus program.
  • Ensure that the Anti-Virus definitions are up-to-date using your preferred product's updating service.
  • Ensure that the latest Operating System Service Packs and Critical Updates have been installed by running Microsoft Update.

This page provides information regarding operating system updates in the unlikely event that an O/S update is incompatible with the X-Stream firmware.

Since new Operating System Vulnerability, Worms, and Viruses are detected frequently, it is highly recommended to periodically ensure your virus definitions and operating system patches are up to date.

New Oscilloscopes

Teledyne LeCroy has selected NOD32 as the tool of choice for protection of Digital Oscilloscopes. We have tested this product fully for compatibility and performance impact. Because some oscilloscope users may prefer another tool for this purpose, or may be planning to use their oscilloscope in standalone mode, Teledyne LeCroy includes NOD32 trial installer on the oscilloscope desktop.

If an oscilloscope protected with Antivirus has been disconnected from the network for an extended period, Teledyne LeCroy recommends updating the virus definition files manually using a CD or USB memory stick before reconnecting the instrument to a network.

Teledyne LeCroy's oscilloscope production lines are updated regularly to ship OS images complete with needed service packs and patches. A recovery partition is included on the hard disk drive of each Teledyne LeCroy oscilloscope. Since it is possible you may receive an oscilloscope from storage or in transit for some period, we recommend routine application of critical OS patches as part of your regular oscilloscope maintenance. Your oscilloscope is expected to provide long service life (Teledyne LeCroy long term support extends for seven years after your oscilloscope is removed from the new product catalog) and therefore your recovery partition does age. If you find it necessary to rebuild an older oscilloscope, service packs and critical updates must also be reinstalled.

New Demonstration Oscilloscopes

Teledyne LeCroy demonstration oscilloscopes are protected with AntiVirus software. Virus definitions are updated and Operating Systems patched at least monthly. If you wish, prior to any demonstration at your facility, you may invite your IT department to examine the oscilloscope before connecting it to your network. Teledyne LeCroy Sales and Applications Engineers, and Service Departments, are equipped with a set of security tools allowing them to keep demonstration oscilloscopes clean and safe for your evaluation.

Oscilloscopes sent for Repair or Calibration

Your oscilloscope is non-invasively scanned for viruses upon receipt at a Teledyne LeCroy service center. If a virus is found, you are contacted and asked how you would like us to proceed. While at Teledyne LeCroy, your machine is carefully protected. Prior to return shipment your oscilloscope is again non-invasively scanned and certified.

Windows 7 and Vista 64 -based Oscilloscopes

All high-end Teledyne LeCroy oscilloscope models ship with the Windows 7 operating system and Service Pack 1 installed. Some initially released units shipped with the Windows Vista 64-Bit operating system installed.

These oscilloscopes offer an increased level of security out of the box due to various Service Pack enhancements such as a default enabled network firewall.

Windows XP Pro -based Oscilloscopes

The WaveRunner 6000 A models, the WavePro 7000 A models, and currently shipping WaveMaster, WaveExpert, SDA, and DDA variants ship with Windows XP Professional with Service Pack 3 installed.

These oscilloscopes also offer an increased level of security out of the box due to various SP enhancements such as a default enabled network firewall.

Oscilloscopes equipped with Windows XP Pro can also benefit from Microsoft's Windows Update service. Users are highly recommended to take advantage of the published critical updates.

Users should monitor the space available on the C drive, when installing Windows updates. If the oscilloscope is running short on C drive space, please contact the Service Department for drive upgrade information.

Windows XP Embedded -based Oscilloscopes

The WaveSurfer product line currently ships with XP Embedded SP3.

XP Embedded, even though virtually identical to XP Pro, cannot currently use the Windows Update service.

It is very important to note that the released Service Pack 2 and Service Pack 3 for Windows XP Home and Professional are not compatible with XP Embedded. Installing this service pack is likely to render your oscilloscope unusable, requiring OS re-installation.

Support for critical updates and service packs are not provided for XP Embedded. XP pro may be installed if software patches and security updates are required. Contact your local Teledyne LeCroy service office for upgrade information.

Windows 2000 -based Oscilloscopes

The WaveRunner 6000 (non-A), older WavePro, WaveMaster, SDA, and DDA oscilloscopes are based upon Microsoft's Windows 2000 Operating System.

The first units shipped at the Service Pack 2 (SP2) level, more recent models ship with SP3, and SP4.

Based on past events, most notably on the pervasiveness of the Blaster, other worms and viruses, Teledyne LeCroy recommends all users upgrade their scope's operating system to Windows 2000 Service Pack 4 which can be found on the Microsoft website at www.microsoft.com.

Before upgrading, note that Service Pack 4 must be installed prior to upgrading or installing scope software version 2.9.1.10 or greater. However, the scope does not operate properly if Service Pack 4 is installed on older scope software versions.

CAUTION

Oscilloscope users MUST first install Windows 2000 Service Pack 4 before upgrade their oscilloscope software to the latest version.

Windows Operating System upgrades on Teledyne LeCroy oscilloscopes should never be attempted on your own and must be exclusively performed by your local Teledyne LeCroy service office.
