Modern test instruments utilize digital technology in place of the analog circuitry that was used in years past. Typically, high-performance analog-to-digital converters (ADCs) and digital-to-analog-converters (DACs) are used in today’s test equipment. This has enabled waveforms to be analyzed and generated with better fidelity at higher frequencies and with increased dynamic range in comparison to previous-generation test instruments. In the application note, “Demystifying the Impact of ADCs and DACs on Test Instrument Specifications,” Keysight Technologies discusses common converter characteristics and their effect on test instrumentation performance...
