PicoScope 3000 Series

Persistence mode

PicoScope’s persistence mode options allow you to see old and new data superimposed, making it easy to spot glitches and dropouts and estimate their relative frequency – useful

for displaying and interpreting complex analog signals such as video waveforms and amplitude-modulated signals. Color-coding and intensity-grading show which areas are stable

and which are intermittent. Choose between Analog Intensity, Digital Color and Fast display modes or create your own custom setup.

An important specification to understand when evaluating oscilloscope performance, especially in persistence mode, is the waveform update rate, which is expressed as

waveforms per second. While the sampling rate indicates how frequently the oscilloscope samples the input signal within one waveform or cycle, the waveform capture rate refers

to how quickly an oscilloscope acquires waveforms.

Oscilloscopes with high waveform capture rates provide better visual insight into signal behavior and dramatically increase the probability that the oscilloscope will quickly capture

transient anomalies such as jitter, runt pulses and glitches – that you may not even know exist.

The PicoScope 3000 Series’ HAL3 hardware acceleration means that, in fast persistence mode, update rates of up to 100 000 waveforms per second are achievable.
