Introduction

Before using the ATS5004D first read chapter 1 about safety.
Many technicians investigate electrical signals. Though the
measurement may not be electrical, the physical variable is of-
ten converted to an electrical signal, with a special transducer.
Common transducers are accelerometers, pressure probes, current
clamps and temperature probes. The advantages of converting the
physical parameters to electrical signals are large, since many in-
struments for examining electrical signals are available.
The ATS5004D is a portable four channel measuring instru-
ment with differential inputs. The native resolution is 12 bits, but
user selectable resolutions of 14 and 16 bits are available too, with
adjusted maximum sampling frequency:
resolution Maximum sampling frequency
12 bit 50 MS/s
14 bit 3.125 MS/s
16 bit 195 kS/s
Table 3.1: Maximum sampling frequencies
With the accompanying software the ATS5004D can be used as
an oscilloscope, a spectrum analyzer, a true RMS voltmeter or a
transient recorder. All instruments measure by sampling the input
signals, digitizing the values, process them, save them and display
them.
3.1 Differential input
Most oscilloscopes are equipped with standard, single ended inputs,
which are referenced to ground. This means that one side of the
input is always connected to ground and the other side to the point
of interest in the circuit under test.
