AMPTD Y Scale
Adjust Atten for Min Clip
Sets the combination of mechanical and electronic attenuation 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 key is pressed.
This key is grayed out in measurements that do not support this functionality. The spectrum analyzer
measurement, Swept SA, does not support this functionality.
Pre-Adjust for Min Clip
If this function is on, it does the adjustment described under “Adjust Atten for Min Clip” on page 858
each time a measurement restarts. Therefore, in Continuous measurement mode, it only executes before
the first measurement.
In dual attenuator models, you can set
Elec+Mech Atten, in which case both attenuators participate in
the autoranging, or
Elec Atten Only, in which case the mechanical attenuator does not participate in the
autoranging. This latter case results in less wear on the mechanical attenuator and is usually faster.
This key is grayed out in measurements that do not support this functionality. The spectrum analyzer
measurement, Swept SA, does not support this functionality.
Max: Dual attenuator configuration: 24 dB
Single attenuator configuration: the total of ATT and EATT cannot exceed 50
dB, so if the EATT is set to 24 dB first, the main attenuation cannot be greater
than 26 dB and will be reduced accordingly; if the main attenuator is set to 40
dB first, EATT cannot be greater than 10 dB

Notes: The SCPI parameter ELECtrical sets this function to On in single attenuator
models. The SCPI parameter COMBined is mapped to ELECtrical in single
attenuator models; if you send COMBined, it sets the function to On and
returns ELEC to a query.
