10 Hardware-Accelerated Fast Power Measurement (Remote Command Only)
10.2 Reset Fast Power Measurement (Remote Command Only)
10.2.10 Frequency Reference Source
Example
:CALC:FPOW:POW1:DEF "FrequencyReferenceSource= InternalFrequencyReference"
Notes Specifies which frequency reference source should be used for this request:
–
If ExternalFrequencyReference is selected and no external reference is present, the
frequency reference unlocks but the data acquisition will continue
–
If AutoExternalFrequencyReference is selected, the hardware senses whether an
external source is present before starting the data acquisition. If no external source is present then
the internal source is selected, and the data acquisition will continue
Preset
InternalFrequencyReference
Range
InternalFrequencyReference, ExternalFrequencyReference, AutoEx-
ternalFrequencyReference
10.2.11 IF Gain
Example
:CALC:FPOW:POW1:DEF "IFGain=10"
Notes Lets you specify the gain at the IF stage anywhere from -6 to 16 dB (1 dB steps). This is an advanced
feature; for most cases this should remain at its default value of 0 dB
Preset 0 dB
Range -6 – 16 dB (1 dB steps)
10.2.12 IF Type
Example
:CALC:FPOW:POW1:DEF "IFType=B25M"
Notes Lets you select between different IF paths. For example, if the signal is less than 25 MHz wide, then you
can select the B25M path to take advantage of additional filtering on this analog IF path
Preset
B40M
Range
B10M, B25M, B40M
10.2.13 Include Power Spectrum
Example
:CALC:FPOW:POW1:DEF "IncludePowerSpectrum=True"
Notes Lets you read data on the entire spectrum for diagnostic purposes. It is not recommended for
production use
