MATH[1]:SPECT
ral:MAG { LINEAr|DB}
MATH[1]:SPECTral:MAG?
Arguments
LINEAR sets the SpectralMag units to linear.
DB sets the SpectralMag units to decibels.
Examples
MATH1:SPECTRAL:MAG DB sets the SpectralMag units for Math1 to decibels.
MATH1:SPECTRAL:MAG? might retu
rn
:MATH1:SPECTRAL:MAG DB indicating
that the SpectralMag units for Math1 are set to decibels.
MATH[1]:SPECTral:WINdow
This command specifies the window function for the spectral analyzer input data
for the specified math waveform. A spectral window determines what the filter
shape of the spectral analyzer will be in the frequency domain. It can be described
by a mathematical function th
at is multiplied point-by-point times the input data
to the spectral analyzer.

MATH[1]:SPECTral:WINdow
{RECTangular|HAMming|HANning|BLAckmanh arris}
MATH[1]:SPECTral:WINdow?
Arguments
RECTangular window function is equivalent to multiplying all gate data by o
ne.
HAMming window function is based on a cosine series.
HANning window f
unction is based on a cosine series.
BLAckmanharris window function is based on a cosine series.
Examples
MATH1:SPECTRAL:WINDOW HANNING applies a Hanning window to the spectral
analyzer input data.
MATH1:SPECTRAL:WINDOW? might return :MATH1:SPECTRAL:WI NDOW
HAMMING
indicating that the window function used to multiply the spectral
analyzer input data is the Hamming window.
