BoBoX breakout boxes

BoBoX1, BoBoX2 and BoBoX3 are versatile breakout boxes for separating and filtering signals from a multipin Fischer connector to BNC connectors in e.g. cryostat dc wiring. Each line can be separately grounded and optional RC filtering can be added inside the unit (BoBoX3). BoBoX3 has non-isolated BNC’s whereas BoBoX1 and BoBoX2 have isolated BNC’s with possibility to individually ground the shield of each BNC. In BoBoX2, each pairs can be individually shorted together. BoBoX1 has selectable RC filtering between each pair. User can choose the component values.

Together with cryogenic Therma filters or Minitherma adapters, these breakout boxes form an easy-to-install filtered wiring for cryostats.

We also provide shielded Fischer cables containing 12 twisted pairs between your equipment and BoBoX. Please ask for a quotation.

Please take a look at the manuals:

Manual for BoBoX3 (old model 2018)

Manual for new BoBoX3 (2022)

Manual for BoBoX2

Manual for BoBoX1

Aivon can also modify the breakout boxes to take into account different amounts and types of connectors (e.g. SMA, LEMO), different switching schemes and so on. Please contact us and specify your needs.
