RF Engineering Laboratory

Created to ensure our customers receive only the highest quality products, our extensive engineering test suite includes industry-standard equipment, such as the 250B Network Analyser and the LA Techniques Vector Network Analyser (LA-13-03). This facility ensures we can deliver a range of testing capabilities, including:

  • Output waveforms, including amplitude, rise time, fall time and duty cycle
  • Tuning slopes and tuning linearity
  • Current consumption
  • DLD, motional parameters, ESR and resonance testing for all crystal package types
  • Source and load impedance for crystal fixtures
  • Pass-band ripple and group delay variation testing for SAW filters and crystal filters
  • Allan deviation
  • Negative resistance testing
  • Oscillation margin determination
  • Temperature testing of oscillators
  • Phase noise measurement of tuneable oscillators

All of our test equipment is aligned with our Symmetricom Rubidium Frequency Standard to ensure the highest quality is maintained at all times. The quality of our services is reflected in our continued conformance to ISO 9001:2015.
