Ultra Low Noise Signal Source for HF receivers testing.
The Ultra low noise signal source generates clean CW signal in 40m HF amateur band with calibrated power and ultra low phase noise.
The source can be used for testing HF receivers and measuring their parameters such as RMDR, IMD3 DR, BDR. It can also be used for S-meter checking / calibration and other purposes that require clean and stable CW signal.
