Phase locked multi channels DDS

MPDS1Cx : Multi outputs DDS locked in phase

AA offers multi-outputs (2 to 8) fixed or variable frequency drivers based on DDS, with phase locked outputs. Based on a common Reference clock, they allow user to create multiple phase locked signals at the same frequency, or stable frequency difference between outputs thanks to the common Reference.

Access to and adjustments of functions is simple with either an Android tablet (with remote control adjustment) or through a RS232 serial link (with computer control) or USB communication.

All parameters are stored in an EEPROM and are automatically loaded after each switch on. Each output is externally controlled by a distinct modulation input signal which can be digital or analog. Additionally, outputs can be simultaneously controlled by a blanking signal.
