Flann's Frequency Meter Series 070 and 072 provide the means to verify the frequency of an R.F. signal independently of electronic circuitry which may be susceptible to interference from the presence of
parasitic harmonics or cross modulation. they are available as a calibrated instrument or direct reading.
Precision Calibrated High Accuracy High Q
The Flann Series 070
Frequency Meter consist of a high Q electroformed precision cavity located on the rectangular waveguide narrow wall. The cavity operated in TE11 mode and is tuned by a non-contacting choked piston. All models have a minimum tuned response of 1dB.
A Micrometer drive ensures precise control of the piston positioning enabling frequency measurement to a high accuracy. Each instrument is supplied with calibration data.
Each model in the Series 072 is simple to operate and offers a high degree of measurement accuracy over the relevant frequency range of typically 0.12%.
The drive mechanism is coupled to a helical drum scale directly calibrated in GHz. The frequency scale length for most models is in excess of 2500 mm and provides high resolution throughout the frequency band.
