Finally, an affordable signal generator for everyone!ERASynth is a high quality portable signal generator at a price point
affordable by everyone including makers, students, universities,
research labs, and start-ups.
Makers/HackersRF signal generators are expensive pieces of test equipment typically
only accessible by pro engineers. ERASynth removes the cost barriers
and makes quality RF signal synthesis accessible to everyone,
especially budget-conscious makers.
StudentsERASynth is for everyone who wants to learn how signal generators
work. Since it is open source with open schematics, students or anyone
who is curious about the inner details of signal synthesis can learn
from ERASynth. You can learn a lot by reverse engineering and hacking,
without having to pay $50k in tuition in engineering program. After
all, learning the design of test equipment turned Jim Williams into
one of the best analog engineers in the world. ERASynth’s advanced
design will certainly teach you several RF tricks.
ProfessionalsProfessional engineers will find ERASynth is a very good alternative
to many of their existing signal generators. If you are professional
engineer, you can compare it yourself: find the lowest cost equipment
on your bench that can give you a 1 GHz signal with -120 dBc/Hz or
better phase noise at 10 kHz offset. Its price tag will be several
times more than ERASynth’s. See the comparison charts below to learn
more about how ERASynth compares to common signal generators.
Professors/Researchers/Start-upsWith all the cuts in research funds, who can afford to spend tens of
thousands on signal generators? Whether you are a college professor
studying Gigasample converters or a start-up developing
state-of-the-art converter technology, you need to clock ADC/DAC
somehow. Check out the specs, you will find ERASynth may very well be
your next clock source. Besides the price, ERASynth’s portability will
definitely help when you are out in the field.
Anyone ElseERASynth is for anyone interested in RF testing. Below is a short list
of application areas where users can take advantage of ERASynth:
General purpose RF testing. For example, to measure the gain of an
amplifier, ERASynth can be used as the source.
Test signal source for SDR. People who are using any of the many SDR
platforms can use ERASynth as the test signal source for testing and
calibration of their SDR devices.
An agile LO source for up and down-converters.
Clock source for ADCs and DACs. When equipped with an optional OCXO,
ERASynth's jitter performance exceeds the requirements of
state-of-the-art giga-sample data-converters.
