14 QPSK EVM Measurement
Meas
Mechanical Attenuation
Example
CALC:FPOW:POW1:DEF "MechAttenuation=10"
Notes
The mechanical attenuation value parameter sets the amount of mechanical attenuation anywhere from 0
to 70 dB (2 dB steps).
Preset
0 dB
Range
0 – 70 dB (2 dB steps)
Default Unit
dB
Initial S/W
Revision
A.14.00
Preamp Mode
Example
CALC:FPOW:POW1:DEF "PreAmpMode=Low"
Notes
The license for the appropriate preamp is required.
The preamp mode parameter specifies whether the preamps are being utilized. Low allows any preamps up
to 3.6 GHz, and Full allows all licensed preamps. Set "ElecAttBypass=True" in order to utilize any preamps.
Preset
Off
Range
Off, Low, Full
Initial S/W
Revision
A.14.00
Resolution Bandwidth Mode
Example
CALC:FPOW:POW1:DEF "PreAmpMode=Low"
Notes
The resolution bandwidth mode parameter allows the user to choose whether the RBW filter is automatically
or manually set. The BestSpeed value minimizes measurement time, while the Narrowest value minimizes
RBW size (minimum of two FFT bins per RBW).
To manually specify an RBW, set this parameter to Explicit, and set the ResolutionBW parameter to the
desired value.
Preset
BestSpeed
Range
BestSpeed, Narrowest, Explicit
Initial S/W
Revision
A.14.00
Resolution Bandwidth
Example
CALC:FPOW:POW1:DEF "ResolutionBW=25e3"
Notes
The resolution bandwidth parameter sets the 3-dB bandwidth of the RBW filter. The ResolutionBWMode
parameter must be set to Explicit in order to manually set the RBW.
