Description

where |Xi| is the magnitude of an I/Q pair, X is the mean of the magnitudes for the specified region(s),
and n is the number of data points in the specified region(s).

PPHase

(

page 120

)

Returns the x,y pairs of both rms power (dBm) and arithmetic mean phase (radian) for every specified
region and frequency offset (Hz). The number of pairs is defined by the specified number of regions.
This parameter can be used for I/Q vector (n=0) in Waveform (time domain) measurement and all
parameters are specified by data point in PPHase.

The rms power of the specified region may be expressed as:

Power = 10 x log [10 x (RMS I/Q value)] + 10.

The RMS I/Q value (peak volts) is:

where Xi is the complex value representation of an I/Q pair, Xi* its conjugate complex number, and n is
the number of I/Q pairs in the specified region.

The arithmetic mean phase of the specified region may be expressed as:

where Yi is the unwrapped phase of I/Q pair with applying frequency correction and n is the number of
I/Q pairs in the specified region.

The frequency correction is made by the frequency offset calculated by the arithmetic mean of every
specified region’s frequency offset. Each frequency offset is calculated by the least square method
against the unwrapped phase of I/Q pair.

Note 1

MIN, MAX, MEAN, DME, RMS, RMSC, SAMP, SDEV and PPH return one data value for each
specified region (or

"Calculate/Compress Trace Data Query (Remote Command Only)" on page

116

) of trace data, for as many regions as possible until you run out of trace data (using

"Calculate/Compress Trace Data Query (Remote Command Only)" on page 116

to specify regions).

Alternatively, they return the number of regions you specify (using

"Calculate/Compress Trace

Data Query (Remote Command Only)" on page 116

), ignoring any data beyond that.
