(Amplifier only)
1. Measured with an swept sine wave source or step with FFT. Frequency of oscilloscope
channel subtracted from the measurement.
2. Measured with an SDA 18000 oscilloscope. Step optimized for eye diagram.
3. Measured with an SDA 18000 oscilloscope using SDEV function to remove offset.
