Dual Frequency Synthesizer and RF Driver

Manufacturer's part number :


Manufacturer Isomet


Description :

The iSPA-SF2 dual output driver is designed to operate with AO modulator pairs, deflectors, tuneable filters and frequency shifters. The driver includes a direct digital synthesizer (DDS), a 32-bit ARM processor (featuring internal FLASH, RAM, ADC and USBII interface) and dual RF amplifiers. The driver can be directly controlled in real time via USB or may be pre-programmed for autonomous operation. External controls are applied through a 25way D-type connector.

The driver can be easily programmed to output sweeps or step changes in frequency or phase or amplitude.
