APERror.
<aper>::=<NRf>
is the phase error RMS in degrees or radians.
PPERror.
<pper>,<symb>
Where
<pper>::=<NRf>
is the phase error peak value in degrees or radians.
<symb>::=<NRf>
is the symbol number for the phase error peak value.
RHO.
<rho>::=<NRf>
is the measured value of waveform quality (
ρ
).
SLENgth.
<slen>::=<NR1>
is the number of analyzed symbols.
FERRor.
<ferr>::=<NRf>
is the frequency error in Hz.
OOFFset.
<ooff>::=<NRf>
is the origin offset in dB.
STABle.
#<Num_digit><Num_byte><Sym(1)><Sym(2)>...<Sym(n)>
Where
<Num_digit>
is the number of digits in <Num_byte>.
<Num_byte>
is the number of bytes of data that follow.
<Sym(n)>::=<NR1>
is the symbol data.
n: Max 512000 (= 1024 points

500 frames)
PVTIme.
#<Num_digit><Num_byte><Data(1)><Data(2)>...<Data(n)>
Where
<Num_digit>
is the number of digit in <Num_byte>.
<Num_byte>
is the number of bytes of data that follow.

AMAM.
<Comp>,<Coeff_num>{,<Coeff>}
Where
<Comp>::=<NRf>
is the 1 dB compression point in dBm.
<Coeff_Num>::=<NR1>
is the number of coefficients (1 to 16).
It is equal to the value set using the [:SENSe]:DDEMod:NLINearity:COEFfi-
cient command plus 1.
<Coeff>::=<NRf>
is the coefficient value.
