We do not currently carry noise sources. You can look at Keysight’s 346A or B or Noisecom’s NC346A or B. I would recommend a 346B (or NC346B) for most testing, and if your gain is too high, pad it down at the output to around 20 dB for best results. The higher ENR generally provides better measurements, but not if you saturate your RF input.
