MODEL: Ultracomb-8G

Comb Generator

Variable Width 20V-Differential Ultra-High Rep Rate Low Jitter USB Microwave Comb Generator


Based on a custom ultra-high-repetition-rate GaN differential pulser IC, the palm-sized Ultracomb-8G is powered from any USB3.0/3.1 port through which the user can program comb amplitude, comb picket spacing and low/high-frequency spectral weighting. Comb picket spacing can be software-programmed to any frequency from 10MHz to 2GHz in single-ended-output mode (10-50MHz in differential output mode) in 0.01 Hz steps, generated by an on-board LMX2594 synthesizer driven from an internal 150fs-jitter reference clock or external 10-500MHz reference. The unit can also be programmed in 1:1 clock mode, enabling the pulse repetition rate of the comb generator (and the comb tooth spacing) to be the same as the external reference/clock input. Its differential outputs enable direct antenna connections without the use of a BALUN, and 3dB higher total output level.

All models include Windows 10 and RedHat Linux 7.6 and Centos Linux 7.6 drivers and user programs with full source, as well as a comprehensive QT control panel
