Frequency recording


The "Frequency recording" program is used for measuring and recording of frequency of signal on input of the FMTR module. The program was designed for application in quartz crystal microbalances. It can be used in any applications where is necessary measuring of frequency.

Hardware

The program controls the KSP measurement system with following modules:

 FMTR-710 - frequency/period meter module

 This sytem allows to measure high and low frequency with the same precision. This meter is based on the two counters counting input pulses and reference pulses. Base time of counting is selected by software. Real time of counting is synchronized by imput pulses. Input frequencies: 0.0024 Hz to 20 MHz. Higher frequencies than 20 MHz are measured after connecting of a frequency divider on the input. The FMTR-710 module has 7 inputs selected by software.


Features of the program
 
  • Run, Stop, Pause, Continue commands
  • saving of data and printing of the report
  • writting of data as a text file for using in worksheets and graphic programs
  • setting up to 10 methods (sets of measurement parameters and experiment descriptions)
  • readout of data directly from the graph
  • readout of curve slope directly from the graph
  • zoom of the graph
  • displaying and drawing measured value or difference this value and base frequency
  • locking current measured frequency as a base frequency or manual writting this frequency

  • Main window of the "Frequency recording" program
