Leader Ldc-824 10 MHz - 520 MHz Frequency Counter

Leader LDC-824 Digital Frequency Counter Technical Specifications

• Operating Frequency Limit: Wideband high frequency detection and counting capability from 10 Hz to 520 MHz.

• Input Sensitivity: 20 mVrms at 10 Hz to 80 MHz; 30 mVrms / 50 mVrms at high frequencies from 80 MHz to 520 MHz.

• Input Impedance: Standard 1 MΩ (Ohm) high impedance and 50 Ω (Ohm) low impedance options available on the front panel, depending on signal requirements.

• Maximum Input Voltage: Up to 200V (DC + AC peak) for safe operation at low frequencies; 520 MHz high frequency channel provides safe signal level protection (5 Vrms max).

• Gate Time Options: 0.1 second, 1 second, and 10 second gate timing (Gate Time / Multi) settings, easily selectable with front panel buttons.

• Measurement Modes: Frequency measurement (Freq), period measurement (Period) and functional control buttons that allow switching between x10, x100, x1000 multiplication factors.

• Display and Indication Structure: 8-digit high-visibility digital display panel that provides clear tracking of measured values, units (M, k, Hz, µ, s) and operating conditions (Gate, Over).

• Connection Type: 1 BNC type secure input connector located on the front panel, which ensures lossless transmission of high-frequency signals.
