TDS 210 and TDS 220 Frequently Asked Questions

  1. Didn't Tektronix already do a recall? Why is the company putting its customers through this again?
    Tektronix began the first phase of this ongoing recall in June of 1998. Although a substantial number of the affected units were returned for modification, Tektronix is continuing its efforts to reach customers who have an affected TDS 210 or TDS 220 oscilloscope that needs to be modified.

  2. How do I determine if my TDS 210 or TDS 220 oscilloscope is subject to the recall?
    This ongoing recall applies to TDS 210 and TDS 220 oscilloscopes with serial numbers falling within one of the following ranges:
    TDS 210:
    B010100 to B049399
    BU10000 to BU50199
    C010000 to C010879

    TDS 220:
    B010100 to B041059
    BU10000 to BU50199
    C010000 to C011174


    The TDS 224 is not subject to this recall.


    To find the serial number of your TDS 210 or TDS 220 oscilloscope, check the rear panel. If the product's serial number falls within one of these ranges, your product may be subject to the recall. On the back panel, if you see a white, vertically oriented, rectangular Tektronix label marked "P.S. MOD SUP 40-003", it means the oscilloscope has already been modified. Modified products are not subject to the recall and need not be returned. The rear-panel photographs on this Web site show the serial number and modification stickers. To confirm the recall status of your model, you may also enter its serial number into the Serial Number Verification Tool search field provided on this site. Products with serial numbers outside all of the ranges shown above, or products that have already been modified, are not subject to the recall.

  3. How do I determine if my TDS 210 or TDS 220 oscilloscope has already been modified?
    If you see a white, vertically oriented, rectangular Tektronix label marked "P.S. MOD SUP 40-003", it means the oscilloscope has already been modified. Please see photos.   Modified products are not subject to the recall and need not be returned. To confirm the recall status of your model, you may also enter its serial number into the Serial Number Verification Tool search field provided on this site.

  4. What exactly is the problem?
    Tektronix has determined that certain incorrect use of our model TDS 210 and TDS 220 oscilloscopes (which are subject to the recall) may cause the ground connection to fail on these products, potentially exposing the user to risk of serious personal injury or death. If a user incorrectly connects a probe ground lead to a voltage source, or incorrectly touches the ground ring near the probe tip to a voltage source, a circuit board trace in the product's electrical ground path may open. Thereafter, the product may appear to function normally; however, the unit is no longer properly grounded. Subsequent use of the product could then result in a serious electrical shock to the user. We are conducting a recall to prevent this possibility of injury to Tektronix customers.

  5. How does a customer know if its product has an open ground connection?
    The product will not display any visible outward sign that it has been damaged after the incorrect use; all of the damage is internal. The product will appear to function normally when used. Consequently, even if the product is functioning properly, you should not assume that it does not have an open ground connection. If your product's serial number falls within one of the designated serial number ranges and the product has not been modified, you should immediately stop using the product and send it to the Tektronix Authorized Recall Center in your geography for modification.

  9. I have twelve TDS 210s; do I still ship them UPS?
    In the U.S., for quantities of 10 units or more, you should use Airborne, Burlington, or another preferred carrier. In European Union countries, call the nearest Tektronix Service Center for instructions. For other countries, call your TDS200 Recall Center (see the Recall Return Instruction Sheet ) for international shipping instructions, or contact your local Tektronix service provider.
    These larger product quantities should be shipped as a unit, either boxed or palletized, to ease handling and to control shipping costs. Products should be packaged in the original product packaging if available. Otherwise, the product should be inserted in a plastic bag and then properly packaged to ensure the product is not damaged during shipment. For a Tektronix billing number, or for additional information, please call the Authorized TDS200 Recall Center nearest you. Instructions on how to return TDS 210 and TDS 220 units can be found on the Return Instruction Sheet .
