13 Modulation Accuracy (Composite EVM) Measurement
Meas
Default Unit
Boolean
Initial S/W Revision
A.14.00
Channel Bandwidth Array
Example
CALC:FPOW:POW1:DEF "Bandwidth=[3.84e6, 5e6, 3.84e6]"
Notes
The bandwidth parameter array defines the bandwidth of each channel that will be measured.
All array parameters should have the same number of elements. Alternatively, if all the elements are the
same value, a single number with no square brackets can be used to define the parameter.
Preset
[1e6]
Range
0 to 40 MHz
Default Unit
Hz
Initial S/W
Revision
A.14.00
Channel Filter Type Array
Example
CALC:FPOW:POW1:DEF "FilterType=[RRC, IBW, RRC]"
Notes
The filter type parameter allows the user to choose between an integration bandwidth (IBW) filter or a root-
raised-cosine (RRC) filter. The integration bandwidth filter weighs all frequencies within the bandwidth
equally. The root-raised-cosine filter has an associated shape parameter, defined by the FilterAlpha
parameter.
All array parameters should have the same number of elements. Alternatively, if all the elements are the
same value, a single value with no square brackets can be used to define the parameter.
Preset
[IBW]
Range
IBW, RRC
Initial S/W
Revision
A.14.00
Channel Filter Alpha Array
Example
CALC:FPOW:POW1:DEF "FilterAlpha=[0.5, 0.0, 0.5]"
Notes
The filter alpha parameter allows the user to adjust the alpha value associated with the root-raised-cosine
(RRC) filter type. Set FilterType to RRC in order to utilize this parameter.
All array parameters should have the same number of elements. Alternatively, if all the elements are the
same value, a single number with no square brackets can be used to define the parameter.
Preset
[0.22]
Range
0.0 – 1.0
