Frequency converters are used to scale-up or scale-down the
frequency of an input signal. The output signals are a function
of the input and there are no distortions in the phase angle.
While selecting a frequency converter, you need to consider the
number of analog input channels that will be used. Single-ended
is used for single-ended channels. In differential channels the
output is the difference between two input signals. The device
can run on AC voltage or current as the input. There are
different styles of frequency converters to choose from. These
include IC or board mount, circuit board, panel or chassis
mount, modular bay or slot system, DIN rail, rack mount, and
stand-alone. There are also several user interface choices for
frequency converters. These include none, front panel and
display, touch screen, handheld or remote programmer, and
computer programmable. Some other important features to look for
in frequency converters are: - bandwidth, which is the
difference in the low and high limiting valu
