Lock-in amplifier with integrated boxcar averager

Summary

The procurement is for one lock-in amplifier with an integrated boxcar averager for synchronised control and data acquisition in a magneto-optical Kerr microscope. The device must support static imaging and time-resolved measurements with optical and radio-frequency excitation, control a piezoelectric sample scanner, and capture the scanner position alongside the measurement signal. Requirements include demodulation from DC to at least 500 kHz with at least four independent demodulators, input noise no greater than 5 nV/√Hz from 10 kHz, dynamic reserve of at least 100 dB, and an integrated boxcar averager with a repetition rate of at least 100 kHz and a minimum window no wider than 20 ns. Specified analogue, signal, trigger and reference inputs and outputs are also required, as are a 10 MHz reference-clock input, continuous timestamped data transfer of at least 10 kSa/s, and a documented Python interface for use in a TANGO/Sardana environment. Delivery is required within a maximum of six weeks after the order, DAP Max-Born-Straße 2A, 12489 Berlin (Incoterms 2020). Installation, assembly, integration and commissioning are not part of the supplier’s obligations. The bid must state the net price and expected delivery time. Price is the sole award criterion (100%); confirmation that the minimum requirements are met and acceptance of the contracting authority’s terms are mandatory, or the bid will be rejected. Bids must be submitted electronically and, unless otherwise permitted, in German. The submission deadline is 13 October 2026 at 13:00.
