1. 1 ms/point, 1 MHz to 10 MHz, typical.
2. Dynamic range is defined as the difference between output power and receiver noise floor.
3. Decrease specification by 20 dB below 10 MHz. Decrease specification by 5 dB between 8 GHz and 14 GHz.
4. High Level Noise below 20 MHz is increased by a factor of 5.0.
