The 845-M is a wideband low phase-noise synthesizer operating up to 20 GHz. The module has a milli-Hz frequency resolution and uses a high-stability internal reference. The internal reference can be phase-locked to a programmable external reference.
The module has a USB and LAN interface and can be controlled using SCPI 1999 command sets. This small module operates with an external 6V DC supply and includes BNC’s SigGen GUI software package.
