15 Power Control Measurement
Meas
DC Coupled
Example
CALC:FPOW:POW1:DEF "DCCoupled=True"
Notes
The DC coupled parameter allows the user to specify whether the DC blocking capacitor is utilized. Set
parameter to true when measuring frequencies below 10 MHz.
Preset
False
Range
True (DC Coupled) or False (AC Coupled)
Default Unit
Boolean
Initial S/W
Revision
A.14.00
DetectorType
Example
CALC:FPOW:POW1:DEF "DetectorType=Peak"
Notes
Option FP2 is required.
The detector type parameter allows the user to choose whether a RMS average or peak value is used
during the measurement.
Preset
RmsAverage
Range
RmsAverage, Peak
Initial S/W
Revision
A.14.00
Do Noise Correction
Example
CALC:FPOW:POW1:DEF "DoNoiseCorrection=True"
Notes
When noise correction is enabled, the linear noise power contributed by the analyzer is subtracted from all
measurements. This effectively lowers the noise floor of the analyzer.
When noise correction is enabled, the first measurement for a given set of input parameters will take extra
time. This is because the analyzer takes an extra acquisition with the RF input disconnected from the
analyzer’s front end to measure the noise of just the analyzer. The measured noise floor is stored in a cache
so the noise acquisition will occur only once for the same state settings. In other words, if noise correction
was turned on and the analyzer made an acquisition at frequency A, then frequency B, and back again to
frequency A, the hidden initial noise floor acquisition would only occur for the first acquisition at frequency A
and the cached noise floor would be used the second time frequency A was measured.
Preset
False
Range
True (enable noise correction) or False (disable noise correction)
Default Unit
Boolean
Initial S/W
Revision
A.14.00
