Latest Digital and High Frequency Technology

STS (Smart Transceiver System)

STS offers high performance in a compact size using a fusion of integrated digital circuit technology and the latest high frequency technology. The design, optimized for efficient transceiving and high precision digital signal processing, gives rapid and precise control of RF (radio frequency). The compact unit is equipped with signal receiver and transmitter functions that allows generation of up to 8 independent frequencies, and enables event control at 5 nanosecond resolution.

The receiver system uses high speed sampling at 16 bit 100 Msps, maximum observation range 10 MHz, and improves the effective dynamic range up to the equivalent of 22-24 bits using a high over-sampling rate. The use of a 64 bit acquisition word length ensures error-free prolonged measurements.


Lock feedback circuitry

The lock feedback circuit provides digital control of the interlock between the lock frequency and the shim controller. It provides accurate digital control of the response necessary for any magnetic field variations arising from environmental changes.


Highly stable temperature control system

The improved response in the probe heater and control unit achieves highly stable sample temperatures. The high speed control bus line that connects the spectrometer to attachments has been improved and provides rapid and stable operation of attachments. By incorporating the NMR lock function and the magnetic field gradient control function into one module, the interlock between the lock feedback circuit and the spectrometer control computer is enhanced. This makes possible the precise response necessary for any magnetic field variations arising from environmental or other changes.


Enhanced usability

The head amp chassis is equipped with functions that facilitate probe tuning. A touch panel display at the top of the head amp chassis provides an intuitive user interface. The panel displays items that are helpful for each step in operation, including a reflective dip and value (bar) for probe tuning, and the remaining cryogen amount when refilling liquid helium or liquid nitrogen. This significantly enhances the ease of operation.


Intuitive control software

Incorporating an additional interface for simple, routine operation, the Delta™ software for spectrometer control and data processing supports both simple and sophisticated applications. A minimum sequence of operation is needed for routine, standard analysis, such as selection of a solvent or measurement mode. For more complicated analysis with numerous conditions, the system will automatically define hardware parameters, including those for the spectrometer and probe, allowing the operator to set up only the conditions specific to the sample or research objective.
