Can 53220A Measure 1 Hz Signal With Measurement Rate at 1 Reading/s?

Frequently Asked Questions (FAQs)SummaryReason of measurement rate is about 3 reading/s.QuestionCan 53220A Measure 1 Hz Signal With Measurement Rate at 1 Reading/s?AnswerIn addition to DC coupling, we should also turn off the auto-level (use a fixed level) and turn off the measurement time out or set it to several seconds (Utility - Instr Setup - Time Out Settings - Time Out (Off)). With this configuration and 1 second gate time, I can make a measurement approximately every three seconds. The reason measurement is not taken every second is that after completing a measurement, the counter must wait for at least one cycle for the next edge and level to occur (the counter does not stop and start a measurement on the same edge). Also, synchronization and interpolation within the counter before each measurement may require additional input cycles.
