14 QPSK EVM Measurement
Meas
excursion value stored under the Peak Criteria menu.
Values must be provided for threshold and excursion. The sorting and display line parameters are
optional (defaults are AMPLitude and ALL).
Note that there is always a Y-axis value for the display line, regardless of whether the display line
state is on or off. It is the current Y-axis value of the display line which is used by this command to
determine whether a peak should be reportedSorting order:
AMPLitude - lists the peaks in order of descending amplitude, with the highest peak first (default if
optional parameter not sent)
FREQuency - lists the peaks in order of occurrence, left to right across the x-axis.
TIME - lists the peaks in order of occurrence, left to right across the x-axis.
Peaks vs. Display Line:
ALL - lists all of the peaks found (default if optional parameter not sent).
GTDLine (greater than display line) - lists all of the peaks found above the display line.
LTDLine (less than display line) - lists all of the peaks found below the display line.

Hardware-Accelerated Fast Power Measurement (Remote Command Only)
The Fast Power option (FP2) enables very fast channel power measurements for instruments with the
prerequisite hardware (DP2 and/or B40). It accomplishes this by peforming real-time overlapped FFTs at
the hardware layer, using software for basic post-processing before returning the result to the user. The
upshot of this approach is improved throughput for user applications that require many sequential power
measurements.
The analysis bandwidth of FP2 is limited by the licenses in the instrument, but its maximum overall analysis
bandwidth per acquisition is 40 MHz.
FP2 is remote-only, which means the instrument does not switch to any particular mode or measurement.
FP2 commands can be sent while another application is in use on the front panel.
Each Fast Power measurement can be predefined using an array index, and up to 1,000 measurements can
be stored. In the following documentation, instances of [1,2,…,999] can be substituted with a particular
measurement index, e.g. CALC:FPOW:POW1?, CALC:FPOW:POW2?, CALC:FPOW:POW134?. In this way,
power measurements can be defined one time in a batch, and then executed multiple times without having
to redefine them, similar to “list mode” on other measurements.
In addition to basic channel power measurements, there are a number of other measurement “functions”
for each channel, including peak power, peak frequency, and power spectral density. See the Function
parameter for more information.
