Adjacent Channel Power—Fast Mode ADC Range

[:SENSe]:ACP:FAST:OFFSet:ADC:RANGe

AUTOAPEakAPLockM6P0P6P12P18P24

[:SENSe]:ACP:FAST:OFFSet:ADC:RANGe?

Select the range for the gain-ranging that is done in front of the ADC when the [:SENSe]:ACP:SWEep:TYPE is set to Fast. This is an advanced control that normally does not need to be changed. If you are measuring a CW signal, see the description below.

•Auto - sets the ADC range automatically. For most FFT measurements, the auto feature should not be selected. An exception is when measuring a signal which is “bursty,” in which case the auto featurecan maximize the time domain dynamic range, if FFT results are less important to you than time domain results.

•Auto Peak (APEak) - sets the ADC range automatically to the peak signal level. The auto peak feature is a compromise that works well for both CW and burst signals.

•Auto Peak Lock (APLock) - holds the ADC range automatically at the peak signal level. The auto peak lock feature is more stable than the auto peak featurefor CW signals, but should not be used for “bursty” signals.

•M6 - sets an ADC range that subtracts 6 dB of fixed gain across the range manually. Manual ranging is best for CW signals.

•P0, P6, P12, P18, or P24 - selects ADC ranges that add 0, 6, 12, 18, or 24 dB of fixed gain across the range manually. Manual ranging is best for CW signals.

Adjacent Channel Power—Fast Mode Relative Attenuation

[:SENSe]:ACP:FAST:OFFSet:RATTenuation <float>

[:SENSe]:ACP:FAST:OFFSet:RATTenuation?

Sets a relative amount of attenuation for the measurements at the offset channels when the [:SENSe]:ACP:SWEep:TYPE is set to Fast. This attenuation is always specified relative to the attenuation that is required to measure the carrier channel. Since the offset channel power is lower than the carrier channel power, less attenuation is required to
