10. Appendix
This chapter provides additional explanations of various functions.
10.1. Sampling Data Format
This product has two data formats: normal sampling and P-P sampling.
10.1.1. Normal Sampling
With normal sampling, the A/D value of the sampling period is recorded as data and used for waveform
reproduction and data analysis.
Playback the input waveform from sampling data
If the input signal is too fast for the sampling period, the waveform reproducibility may drop and lead to
the unexpected loss of pulses.
Raising the sampling speed improves the waveform reproducibility but increases the recorded data.
10.1.2. P-P Sampling
P-P sampling performs sampling with the data within the sampling period as the fastest sampling (20
MS/s), to detect the peak values (maximum value and minimum value) and record those peak values as
the recorded data.
This data format is suitable for the waveform playback of long-term recording, as it enables waveform
reproducibility of a wide band of data, without sudden spike noise, etc.
A disadvantage is that it cannot perform data analysis after recording (average, RMS, FFT, etc.)
