Technology for measuring and testing
we divide into the following basic categories:
A multimeter
represents a module that converts analog value voltage, current or resistance),
carrying the information we are interested in. The most important parameter
is usually the accuracy.
A digitizer
converts voltage to digital number, too. To the contrary of multimeters
it operates faster, usually not so accurately and with higher number
of signals (input channels).
Switching means changing the signal
path under the system control. It can be organized in several ways as well.
A multiplexer joins one of many inputs to
output and vice versa. A matrix joins any one
of many inputs to any from many outputs. A switch
is a simple connecting point (contact) controlled separately and independently.
A counter
counts impulses during certain period of time. Similar module, timer,
measures time between two pulse occurrences.
Digital input and
output is a gate the digital information flows through. It connects
the testing system with the digital world around. If the system is networked,
the network is not counted as a part of digital input and output however.
Generators create output voltage according
to control numbers from the controller. We divide them into three categories.
The pulse generator creates series of pulses.
The functional generator creates repetitive
form of common signals - sine, pulse or even triangular one. The
random generator accepts sequences of numbers and converts hem into
sequences of voltages at the output.
Off course systems are composed
of many other modules, such as control computers, mainframes, amplifiers
or special modules. The software is equally important part in any testing
system. Due to the diversity we can hardly list these modules in tables
and it is absurd to compare them. Naturally these modules are included
in a system design we offer to prepare. Here
you can step into the questionnaire to describe us your requirements.
