[:SENSe]:CORRection:PAMPLifier:SPOT:DISTribution <char>

(Read-Write) Set and query the preamplifier specified fixed value. This value indicates the nature of the entered value relative to the population of values it represents. (i.e., Fixed, Rayleigh, or Uniform (Uniform in Circle).

Note: Only available when CORR:PAMP:MOD is set to SPOT.

Parameters

<character>

Preamplifier Spot mode's distribution value. Choose from:

RAYL - The probability density function (pdf) of the magnitude of the reflection coefficient is a Rayleigh distribution. This is normally the case for specified values when the overall mismatch is due to several interacting impedance transitions within the device.

UNIF - A distribution that was historically used in the industry, before the Rayleigh research, as documented in Keysight Application Note 1449-3, but is rarely accurate. Refer to https://literature.cdn.keysight.com/litweb/pdf/5988-9215EN.pdf.

FIX - The reflection coefficient magnitude is always at the given level. This is often the case when measured values are used.
