Previous generations.
Instruments we no longer build. They are listed here because an owner still needs the manual, the last software release, and an honest answer about repairs.
Documentation stays up
Manuals, wiring diagrams and the final software release stay in the download center. We do not retire files when we retire a product.
Open the download center →Repairs, where parts allow
Older instruments are assessed one by one. Send us the model and serial number and we will tell you honestly whether it can still be repaired.
Ask about a repair →Your old unit has value
Most of these instruments are worth something against a current one. The trade-in programme quotes you before you ship anything.

Newest first. Where a year is missing, the record does not say — tell us if you know it.
Not listed here?
We built instruments for fifty years and not all of them made it into this list. Tell us the model and the serial number and we will find what we have.
