A key benefit of the real-time controller TRC6 is the direct access and visualization of all raw signals. This is available in the system, eliminating the need for pre-processing and data-rate reduction in add-on instruments. 

To ensure a low-latency and reliable data transfer at a significantly higher speed than before, a revolutionary data transfer architecture was designed. It supports a 7× higher data transfer rate, sampling rates up to 200 MS/s, synchronous data input and output over all interfaces in the system, and plug & play operation.

Designed for distributed measurements and optimized for low HF signature and small signals, the architecture enables a placement of the signal interfaces at a significant distance from the central processing core. The TRC6 uses galvanically isolated optical fibers. For complex measurements, a single system can handle over 128 outputs or inputs and over 250 monitoring signals, with over 200 signals simultaneously available in the user interface. To handle this enormous amount of data, the TRC6 offers increased processing power with a larger FPGA, a more powerful CPU, and faster storage.

The signal conversion modul TSC6 redefines the meaning of signal interface, offering state of the art performance for quantum transport measurements in any experimental situation.

The 24-bit 2 MS/s ADCs paired with a low-noise, low-drift input stage with variable gain and 200 kHz bandwidth, offer noise as low as 7 nV/sqrt(Hz) and effective resolutions of up to 25 bits, with oversampling being effective down to 1 Hz. A high-impedance input buffer with input bias current below 2 pA, true-differential inputs, selectabe AC-coupling, and flexible GND schemes ensure optimal operation with any sample and electrical configuration.

The 31-bit DAC architecture delivers incredibly clean signals down to smallest amplitudes, with effective resolutions above 24 bit. Output spectral density noise is as low as 10 nV/sqrt(Hz) (±10 V range) or less than 3.5 nV/sqrt(Hz) (±2.5 V range). Output current and voltage are constantly monitored, which allow leakage current detection, and all outputs can act as regulated current sources with maximum currents up to 25 mA. 250 kHz bandwidth and advanced multifrequency functionality allow the TSC6 to replace up to 8 lock-in amplifiers.

A signal generator leaving nothing to be desired: The TOC6 is a signal generator and digitizer offering bandwidths in excess of 25 MHz with exceptional signal performance down to DC and unique signal parameters. On top of userselectable output amplitude ranges, the TOC6 offers variable filters, which reduce high-frequency noise above the required bandwidth. For low-capacitance loads, the complete output stage can be bypassed, reducing noise levels to less that 5 nV/sqrt(Hz).

The fully differential input stage can be easily adapted to the source impedance, offering userselectable 50 Ohm / 100 MOhm / high impedance settings. A low-noise mode reduces noise to below 4 nV/sqrt(Hz), while a low-capacitance mode lowers input bias current and input capacitance. These features, make the TOC6 a unique digitizer for high-impedance samples, operating from DC with a low 1/f corner up to 25 MHz with excellent dynamic performance. A monitor output adds the functionality of a lownoise, high input impedance, 25 MHz bandwidth differential voltage preamplifier.
