RigExpert Tokenblauser – Low-noise, Quad Channel GPSDO

RigExpert Tokenblauser – Low-Noise, Quad-Channel GPSDO provides a satellite-disciplined reference for laboratory, RF and microwave applications. Four independently programmable clock outputs operate alongside a separate fixed 10 MHz reference. This allows compatible equipment requiring different reference frequencies to share one clock platform, without limiting every connection to 10 MHz.

Four Programmable Outputs and a 10 MHz Reference

The RigExpert Tokenblauser has four PLL-synthesised outputs, labelled A to D, support independent frequency entry from 0.16 to 200 MHz in 1 Hz steps. Fine adjustment is available in 1 ppt steps. All five clock outputs use BNC connectors and standard 3.3 V CMOS signalling. Confirm the receiving equipment’s waveform, voltage and input requirements before connection.

GNSS-Disciplined Frequency Stability

RigExpert Tokenblauser receives GPS and Galileo signals through an external active antenna. Published frequency stability is 0.001 ppm or better, with performance dependent on configuration, antenna location and satellite reception. The manufacturer identifies laboratory references, QO-100 and SHF systems, and narrow-band digital modes as intended applications.

Front-Panel Control and USB Connectivity

A 0.91-inch monochrome OLED and three buttons provide local control. Four frequency profiles allow stored output settings to be recalled. The USB Type-B interface presents a virtual serial port for computer communication and diagnostic data. USB does not power the device; the manufacturer’s manual specifies a separate 9–15 V DC supply, rated up to 1 A.

Open-Source Experimentation Platform

Arduino SAMD21 compatibility and open-source firmware support advanced experimentation. Documented facilities include Arduino serial plotting, TimeLab-compatible diagnostic output and transparent access to the GNSS module. Higher frequency limits and alternative electrical output formats depend on hardware, firmware or component changes and are not standard plug-and-play specifications.
