8-Digit LED display Few switches, Easy Operability Quickness, High resolution Compact Design, Excellent for field operations

AT-F Series Frequency Counter is 8-bit high-brightness LED display advanced frequency counter with, 4 function operation, low power circuit design, small size, and light weight. It have a high-stability crystal oscillator temperature protection (TCXO high temperature stability of security compensation oscillator 13MHz) to ensure measurement accuracy and wide to check the input signal with frequency, period and cumulative.It has the self-test features such as the choice of input signal attenuation function and Self-locking manual lock.  The feature and functions are controlled by a large-scale microprocessor.Frequency range: 10Hz ~ 2700MHzFrequency display: 8-bit high-brightness LEDGate Time: 0.01S/0.1S/1SAccuracy: ± 1HZ ± 1 count figure ± Time base accuracyTime-base frequency: 13 MHzShort-term stability: ± 3 × 10-9 / SLong-term stability: ± 1 × 10-5,0C ~ 40CLine voltage change: ± 10% eachthe time-base frequency: ± 1 × 10-7Measurement accuracy: ± time base error ± trigger error × wasOscillator: TCXO (temperature of the high stability oscillator compensation 13MHz) Channel 1 (CH1)Input Sensitivity: 10MHz file (10Hz ~ 8MHz) : 75Vrms10MHz file (8MHz ~ 10MHz): 30Vrms100MHz file (10MHz ~ 80MHz): 30Vrms100MHz file (80MHz ~ 100MHz): 30VrmsAttenuator: × 1, 1 / 20Impedance: approximately 1MΩ (less than 35pF)Maximum security voltage: 250V (DC + ACrms, ATT buy 1 / 20)Channel 2 (CH2)Input Sensitivity: 1GHz file (100MHz ~ 1000MHz): 30VrmsImpedance: 50ΩMaximum security voltage: 3V Input power: 220VAC ± 10% 50HzWorking environment: -5oC ~ + 50oC
