Professional, Project Consultancy

Our computer technology combined withour experience means that OnSpec can provide the most up-to-date and comprehensive service to our customers.

We work alongside the customer to design, develop and produce a product to suit the customers needs. With inhouse specialist in RF design, PIC ® (microchip), EMC and power managment we're pretty sure whatever your project OnSpec can help you.

OnSpec has recently been given the task of designing a control unit for a 36" reflector telescope at the University of Cambridge observatory. Because the frequency of mains electricity is not constant the telescope cannot track the sky consistently so OnSpec have designed a control unit which measures the frequency of the electricity and adjusts the output to the motor to compensate.

Another example, OnSpec's Voltage-controlled Crystal Oscillators (VCXOs), have a control range guaranteed from nominal frequency. The frequency of a 250 ppm VCXO at 16 MHz, when the control voltage is smallest, to at least 250 ppm above 16 MHz, when the voltage is largest. In addition, some VCXO'S have adjustment guaranteed at a centre control voltage.

         All our customised oscillators
            have their outputs, inputs, and power supply requirements optimised
            to what our customers want.
                        
 Custom Voltage-Controlled Oscillators can have :-
              
          
 Closely defined pulling ranges, not only a minimum range, but
                a maximum range as well.
              
          
 Better temperature stability.
              
          
 Different output waveforms.
              
          
 Different amounts of pulling and control voltage ranges.
              
          
 OnSpec's RVC-C030 range of oscillators was developed to provide
                a guaranteed adjustment of a VCXO at a particular control voltage,
                where a large pulling range is not needed.
