BoBoX – New 2018 designs

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-isolating BNC’s (or SMA’s) whereas BoBoX2 has isolating BNC’s with possibility to individually ground the shield of each BNC. In BoBoX2, each pairs can be individually shorted together. Together with cryogenic Therma filters, these breakout boxes form a easy-to-operate and filtered wiring for cryostats.

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

Please take a look at the manuals:

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