The TAMS 1701A Frequency Synthesizer provides an easy to use, compact mechanism to generate frequencies in the 0-200 Mhz range. It is particularly suited to controlling system clocks for products under development, but also has uses in factory-floor testing.  Frequencies may be set through the included Windows GUI or programmatically.  It can generate pseudo-random bit sequences over the same frequency range, which are useful in testing communication channels. When used with a laptop computer, the 1701A makes a highly portable solution for use in the field.
