RF TEST
synchronization, a small footprint, and
low cost of test. For example, Keysight
X-Series signal generators provide several
built-in instruments: a function generator
for enabling or controlling devices under
test, a bit error rate (BER) tester for receiver
sensitivity test, a power meter for flatness
correction and general power measurement,
a digital signal processor (DSP) for real-time
signal processing, additive white gaussian
noise, and real-time fading.
McGregor, Newark: First, a multifunction
piece of equipment is more portable, and
less connection is needed during setup.
Second, users only need to calibrate a
single instrument for their test solution. Third, overall cost to purchase
and maintain the test solution is much
cheaper than with individual pieces of
equipment.
Armstrong, RIGOL Technologies: Multifunctional instruments can save space,
reduce cost, and increase usability. Care
must be taken to make sure each instrument function is still intuitive. Newer
instruments, like touchscreen oscilloscopes, make a great platform for many
instrument functions. For performance
and noise characteristics RIGOL keeps
high-performance RF signal generators
in a separate instrument. This maximizes
function and capability.
Tabor Lucid portable RF
signal generator.
Elo, Tabor Electronics: Multifunction
instrumentation is becoming more real
in today's test-and-measurement world.
The ability to synthesize instrument
functionally is much easier to obtain with
the modern class of FPGAs and tools for
programming. Easily reconfiguring hardware such as A/Ds to provide oscilloscope
functionality while also providing DVM
or DMM capability can be had in the multiple personalities hosted by the digital
logic on the instrument. One design could
provide many functions, or discrete instrument functionality. We have taken a
slightly different approach, providing the
same capability in multiple form factors.
In this way, we are providing the best fit
for the environment.
