electrical attenuator. With the mechanical attenuator, TOI, SHI, and compression
threshold levels increase dB-for-dB with increasing attenuation, and the noise floor
does as well. With the electronic attenuator, there is an excess attenuation of about
1 to 3dB between 0 and 3.6GHz, making the effective TOI, SHI, and so forth, less
well known. Excess attenuation is the actual attenuation relative to stated
attenuation. Excess attenuation is accounted for in the instrument calibration.
Adjust Atten for Min Clipping
Sets the combination of mechanical and electronic attenuation and gain based on
the current measured signal level so that clipping will be at a minimum.
This is an immediate action function, that is, it executes once, when the control is
pressed.
The algorithms that are used for the adjustment are documented under "Pre-Adjust
for Min Clipping" on page 1964.
