The Z-COMM SSG series of Smart Phase Locked Loop (PLL) modules provide high performance in a compact package suitable for any number of applications. Fully programmable through a unique Bluetooth interface, or USB cable, the user may adjust functions such as frequency, sweep mode, step time, step size, and power output, among others. LED indicators provide a visual cue of the status of the various functions. Its rugged enclosure lends itself to in-field use as well as bench top testing. The highly reliable output signal, excellent phase noise, and flexibility of an internal reference or input for an external reference, provides RF engineers with an adaptable RF tool.
