Kenwood TMI Corp. FC-757A Universal Counter, 5 Hz - 175 MHz
The FC-757A is a universal counter mounting measurement functions of frequency, period, period average, time interval, frequency ratio and addition accumlation. As a display, it employs an 8-digit LED. Its display resolution is 1 Hz in MHz range measurement and 0.1 Hz in kHz range measurement. For period measurement, the period required for 1 cycle can be measured between 5 Hz and 2 MHz (with a unit of u-sec or m-sec.). For lower frequencies, period measurement is obtained at a higher degree of accuracy than that of frequency measurement. The frequency ratio measurement is effective in comparing two frequencies (as comparison between clock pulses on the digital circuits) and to obtain the ratio between them. Addition measurements are also possible for counting the number of phenomena occured. A gate control is also possible for the manual or external control of the counting operation to a higher degree of Universal Counter (5 Hz - 175 MHz)
