    3. Counter Function descriptions The 9 functions performed by this instrument and how to use them are explained in this section. These functions include: 1) FRQ A (1) Enables the CHA input to receive an input signal and is used in conjunction with the FRQ B input for time interval (A B) and frequency ratio A/B measurements.
  • Page 30 (2) To select the FRQ C input, press the FUN button and then the [F3] button. (3) The MIN/Max or Relative (REL) frequency is set up the same way as explained in steps (2) and (3) of FRQ A. 4) Time interval (A(B) (1) Time interval measures the time between a starting event on CHA and a stop event on CHB.
  • Page 31 6) Ratio A/B (1) This function measures the ratio of the signals applied to the CHA and CHB inputs. (2) To select Ratio A/B press the FUN MORE (F5) F3 (A/B) buttons (3) Apply the signal levels to the CHA and CHB inputs. NOTE: the frequency range of CHA is 10MHz to 120MHz and the CHB frequency range is 0.1MHz to 10MHz.
