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).

Battery swap unit

We have designed and build a battery swapping electronics “BattSwitch” that is based on our earlier uninterruptible battery source. BattSwitch can swap between 1-6 battery pairs and in addition it can contain linear voltage regulators to provide a stable and constant uninterruptible voltage supply for e.g. preamplifiers. Swapping can be controlled both manually and user-specified Read more about Battery swap unit[…]

SMA and BNC boxes

Aivon BNC (or SMA)-box is a BNC (or SMA) jack-to-jack interconnecting box with pads for surface-mount components (size 0603) inside the box. Minimum order quantity 5 boxes. Please ask for a quotation. SMA Box. Length without connectors 35.0 mm (with connectors 50.6 mm). Width 15.1 mm, height 10.2 mm. SMA Box opened. BNC box has Read more about SMA and BNC boxes[…]

Uninterruptible battery power supply

We have designed and built an “eternal” battery power supply unit (PSU). In this 8-channel uninterruptible PSU, each output channel contains two batteries and a charger. One of the batteries is connected to actual output and the other is being charged. An intelligent relay electronics swaps the batteries within few milliseconds and a large capacitor Read more about Uninterruptible battery power supply[…]
