TABLE OF CONTENTS There are two sampling techniques:
series (sequential) sampling with interpolation, and
parallel sampling with holding network [79, Chapter 2].
Series Sampling with Interpolation. The derating measurements as described in Section 2.8 are based on sequential sampling utilizing the soft- and hardware specified by the UCDAS-16G Manual of the Keithley Corporation [80, Chapter 2]. The software program is written in Quick BASIC language. Sampling programs for two and five channels have been used [81, Chapter 2]. Some of the frequently asked questions concerning sequential sampling are addressed as follows.
The A/D converter UCDAS-16G has a maximum throughput (sampling) rate of 70 kHz in the direct memory access (DMA) mode, where the gain is 1.0.
In the Two-Channel Program [81, Chapter 2 ]

from this follows the SAMPLE RATE
= 10,000,000/[ D%(0) D%(1)]
= 10,000,000/[4 58] = 43.1 kHz ? 43 kHz
In the Five-Channel Program [81, Chapter 2 ]
select
from this follows the SAMPLE RATE
= 10,000,000/[ D%(0) D%(1)]
= 10,000,000/[5 37] ? 54 kHz
