Technical Specifications
The YB4365 CRT Digital Readout Oscilloscope features a bandwidth of DC~100MHz (-3dB) with vertical deflection coefficients ranging from 2mV/div to 5V/div (1-2-5 step, 11 ranges). Its horizontal system offers main scan (A) speeds from 0.5s/div to 50ns/div (22 ranges) and delayed scan (B) from 50ms/div to 50ns/div (19 ranges), ensuring precise time-domain analysis. The instrument employs a TTL-level Z-axis modulation with a frequency range of DC~5MHz, and supports a maximum input voltage of 400V (DC+AC peak ≤1kHz). Key functionalities include automatic trigger level adjustment, TV sync triggering, and a built-in 1kHz±10% calibration signal. The compact chassis integrates a switch-mode power supply, enabling stable operation within 90-260V AC voltage ranges. The CRT display provides clear waveform rendering with a resolution of ±3div for voltage measurements and ±4div for time/frequency calculations. 3713
