Important Safety Notice and Voluntary Recall of Tektronix THS3014 and THS3024 Hand Held Oscilloscopes

Dear Valued Customer,

Tektronix is voluntarily recalling all units of its 100MHz & 200MHz 4 channel THS3014 and THS3024 oscilloscopes.

Please stop using these products immediately. This recall applies to the listed models below and affects all units shipped to distributors and end-users.

Affected Items:

Model Numbers



THS3000 Series Handheld Oscilloscope: 100MHz, 4 Channel


THS3000 Series Handheld Oscilloscope with travel kit: 100MHz, 4 Channel


THS3000 Series Handheld Oscilloscope: 200MHz, 4 Channel


THS3000 Series Handheld Oscilloscope with travel kit: 200MHz, 4 Channel

Description of the Problem – The recalled THS3000 Series oscilloscopes are used to observe the exact wave shape of an electrical signal using automatic measurements to obtain readout values. All units shipped with Firmware v1.0 have a potential to display the decimal point of the measurement value in the wrong position. While we are not aware of any incident involving personal injury, this bug poses a potential safety risk for the user, as an unsafe voltage may be indicated as a much lower (safe) voltage. This potential safety risk could result in serious injury or death and therefore led to Tektronix’ decision for a product recall.

Solution – Downloading and installing the latest firmware resolves this issue. The latest firmware can be downloaded here. Inquiries related to this recall effort should be addressed to the following email address: [email protected]

Requested Action – We recommend all end-users to stop using the THS3000 Series oscilloscope until the instrument is updated to the new firmware version. Please download and install the latest firmware located here: If the latest firmware cannot be downloaded or installed please send the THS3K series instrument to your local Tektronix service depot mentioning this THS3K safety recall. A Service RMA request can be submitted by sending an email to: [email protected].

We are undertaking this safety notice and voluntary recall because we place tremendous importance on our customer’s safety and the reputation of our products.

Please accept our apologies for any inconvenience caused by this action.

If you have any questions, please call your local Tektronix sales representative. Regional contact details can be found here.
