Digital/Analog Boards

Specialized repair and diagnostics of mixed-signal digital/analog boards including TTL/CMOS logic gates, active and passive filter circuits (low-pass, high-pass, band-pass), analog-to-digital (ADC) and digital-to-analog (DAC) converters, precision op-amps, multiplexers and signal conditioning circuits. Diagnostic procedures cover logic level testing, noise and offset measurement, filter stability analysis with spectrum analyzers and converter calibration using standard reference signals. Damaged components are replaced with industrial-grade equivalents, followed by full functional testing under real load conditions to ensure signal accuracy and circuit stability.
