10 Hardware-Accelerated Fast Power Measurement (Remote Command Only)
10.2 Reset Fast Power Measurement (Remote Command Only)
Option Description Unit
channel
BandDensity
Total power density within the specified bandwidth of
the channel
dBm/Hz
PeakPower
The peak power value within the specified bandwidth
of the channel
dBm
PeakFrequency
The frequency that corresponds to the peak power
value within the specified bandwidth of the channel.
This frequency is relative to the center frequency
Hz
XdBBandwidth
The half power (-3.01 dB) bandwidth of the highest
amplitude signal that resides within the channel
dB is configurable using "Channel x-dB Bandwidth
Array" on page 2642
Hz
OccupiedBandwidth
The bandwidth at which 99% of the total power
resides within the channel
Percentage is configurable using "Channel Occupied
Bandwidth Percent Array" on page 2641
Hz
10.2.29 Channel Offset Frequency Array
Example
:CALC:FPOW:POW1:DEF "OffsetFrequency=[-5e6, 0, 5e6]"
Notes Defines the difference between the center frequency to the center frequency of each channel
All array parameters should have the same number of elements
Preset [0]
Range 0 to 20 MHz
10.2.30 Channel Occupied Bandwidth Percent Array
Example
:CALC:FPOW:POW1:DEF "OccupiedBandwidthPercent =[0.95, 0.95, 0.95]"
Notes Only applies to channels whose "Channel Measurement Function Array" on page 2640 is set to
OccupiedBandwidth. The occupied bandwidth percent parameter specifies the percent of total
power in these channels. The valid range for this parameter is 0.0 to 1.0, where 1.0 represents 100%.
The default for this parameter is 0.99, which will return the bandwidth that contains 99% of the total
channel power
Preset [0.99]
Range 0 – 1.0
