Model 409B 170MHz 4-Channel DDS Signal Generator. The 409B generates four independent, phase synchronous sine wave output signals and is programmable in 0.1 Hz steps from 0.1 Hz to 171 MHz. Programming is via an RS232 serial interface. Phase is 14-bit programmable and amplitude is 10-bit programmable. Internal memory can store a sequence of settings. The -AC option is available to enable users to step through settings using an external trigger. It is accurate to 1.5 ppm using the on board TCXO timebase or you can use an external timebase, There is also a /R option that provides a way to lock to and track an external 10MHz frequency input. A line powered AC adapter and SOF8_409 windows software on a CD are included.
