Informacja

★ Highly sensitive and dependable frequency Counter permits direct readouts of any frequencies of 10 Hz to 60 MHz. The built-in prescaler circuit extends the reading range to 50 MHz ~ 250 MHz in FC-754A and to 50 MHz — 500 MHz in FC-756, ★ Because of the use of zero blanking circuit, all unnecessary 0s are not displayed while signal is present; only the 0 of the last digit is displayed at nosignal time. ★ Input impedance is switchable to 1M ohms or 50 ohms to minimize the effect of impedance on the instrument to be measured. ★ Six-digit indicator with light emitting diodes for utmost ease of readouts. The last digit indicates frequencies in 100 Hz unit while measuring frequencies in MHz unit. ★ Sampling rates during MHz and kHz display are 0.5 sec. and 1.1 sec. respectively, thus frequencies can be easily read. ★ Very accurate measurements of frequencies with adoption of high quality crystals. ★ Light emitting diode flickers to indicate overflow in the Counter, eliminating errors in readouts.
