DualDAC3 is a dual channel audio frequency arbitrary waveform generator for metrology.
BoBoX2 and BoBoX3 are versatile breakout boxes between Fischer-24 connector and BNC/SMA connectors. Individual grounding and other options available.
Cryogenic RC filters
Compact cryogenic RC filters with 25-pin micro-D Cinch connectors.
Cryogenic non-magnetic sampleholders for measuring electrical properties of samples. Standard and custom designs with e.g. SMA or SMP connecctors.
Let us design and manufacture custom electronics and mechanics for your r&d problem. We can help in looking for funding from Business Finland or other sources. See latest news for some of our designs.
Schematic and layout design and simulation of sensors, amplifiers, battery-powered systems, digital electronics, etc.
2D and 3D design of big and small items, front panels, 3D printed parts, sample holders, etc.
We can make your special cables
Small scale production services
SMP RC-filter 8 channel
An 8-channel 2-stage RC-filter was designed and built. Size 50 mm x 100 mm x 8 mm.
Some custom breakout boxes
A) Breakout box with BNC, individual RC filtering and grounding options. B) Breakout box with SMA connectors, two selectable RC filter options (F1/F2) and grounding switch
BoBoX with selectable RC filters
We have built a BNC breakout for Fischer-24 pin connector with selectable RC filters. The filter takes place between pairs of twisted pair lines (1-2, 3-4, …). It is possible to disable filtering if needed.
We design and manufacture Micro-D25 adapters to various connector types (SMA, SMP, MCX, nano-D etc) or for direct soldering. The adapters can be single block units with all input/output connectors in single enclosure or combinations of micro-D connector, shielded cable and output connector enclosure. Aluminum enclosure as standard, Au-plated copper upon request.
SMA connector panel
Simple and slim 19-inch wide and 1U high aluminum panel with 40 SMA feedthru connectors. We can also modify panel to house different connectors according to your needs.
New Therma filters designed
We have introduced new Therma filter models with more versions and improved EMI shielding. Please take a look at the Therma (cryogenic RC filters) pages.
Exchangeable sample holder for electron pump devices
We have designed and manufactured cryogenic and non-magnetic sample holder with three rf connectors (SMP) and multi-pin dc connector (Omnetics, 21 lines). The design work was made in collaboration with e-Si-AMP consortium consisting of leading metrology institutes (www.e-si-amp.eu). The holder has duplicate dc connector for grounding. This makes it possible to transport sensitive samples between Read more about Exchangeable sample holder for electron pump devices[…]
Automatic battery switch
We have updated the earlier BattSwitch and added automatic swapping every 12, 24 or 48 hours. By moving chargers outside the unit, the newest design is capable of producing four uninterruptible voltages. Thus, one can e.g. build up to +/-24 V regulated voltage supply. Preliminary manual available here.
Small SMP sampleholder
Upon customer’s request, we designed and built a small sampleholder with non-magnetic SMP connectors. The size of the gold-plated copper or aluminum holder is 30 mm x 30 mm. It is easy to customize this design to fit different number of connectors or other features.
Frequency and pulse distribution amplifier available
We have built 1:8 frequency and pulse distribution amplifier FDA/PDA according to open hardware design available at Open Hardware Repository. More information available also there. The amplifier is designed for applications in time & frequency metrology such as 1PPS/10MHz signal distribution from atomic clocks, GPS/GNSS-disciplined oscillators, or other precision timing applications (e.g. PTPv2/White Rabbit networks).
