The Model 425A from Novatech is a precision frequency and phase agile Synthesized Signal Generator that operates from 250 KHz to 350 MHz. It can generate Sine, LVCMOS, and LVDS output signals simultaneously up to 350 MHz in 10 µHz steps with a phase noise of -133 dBc at 10 kHz offset. The output frequency can be controlled from a serial port.
The frequency synthesizer has an integrated ±1.5ppm on-board TCXO clock. When using an external clock source, it has the same accuracy and stability as the clock and remains phase synchronized with other units operated from the same source. It is available a small shielded benchtop case that measures 39 x 107 x 172 mm with BNC connectors. Multiple 425As can be synchronized and used to generate the signals needed for radar, acoustic testing and similar applications.
