Microwave Signal Generator

Microwave Signal Generator

It is a 60 MHz to 12.4 GHz dual channel software tunable RF signal sweep generator controlled by a Touch Screen Tablet via its USB port.It’s dual independent channels can be configured to run as two different frequencies, or the same frequency with different phases. This allows its use in antenna beam steering applications or quadrature signal generation.It also has on board memory so it can be programmed to any frequency, power, sweep or modulation setting to run stand alone in the field. This makes for a highly mobile, low power and light weight solution for your RF signal generation needs.Very low leakage enhances the usable low amplitude signal range and low harmonic contents puts it in a higher class of sources for EMI EMC/ Wireless/Educational/Research applications.
