The error two-port P
H
is assigned to port j of the analyzer. Its transmission matrix H
describes how the system errors modify the measured incident and outgoing
waves at port j:

In the two equations above, a and b denote the waves at the calibrated reference
plane i and j (e.g. the input and output of the 2-port DUT). The m waves are the raw
measured waves of test port i and j. The subscripts "ref" and "test" refer to the refer-
ence and test receivers, respectively. During the calibration the network analyzer
acquires ratios of wave quantities, which leaves one of non-diagonal matrix elements
of G or H as a free normalization factor. The network analyzer uses the normalization

Suffix:
<Ch>
.
Channel number of the calibrated channel.
<PhyPt>
Physical port number, used to select a specific frequency axis in
arbitrary mode (with option R&S
ZNB/ZNBT-K4).
Parameters:
<ErrorTerm>
String parameters describing the different error terms, depend-
ing on the current calibration method; see table below. Each
term contains one complex value (real and imaginary part) for
each sweep point. The parameters must be transferred in full
length. The following strings are allowed:
'DIRECTIVITY'
–
directivity at the <SourcePort>
'SRCMATCH'
–
source match at the <SourcePort>
'REFLTRACK'
–
reflection tracking at the <SourcePort>
'LOADMATCH'
–
load match at the <LoadPort>
'TRANSTRACK'
–
transmission tracking between the <Source-
Port> and the <LoadPort>; see above.
'G11' ... 'G22'
–
G matrix elements, referenced to the <Source-
Port> (irrespective of the values of <port1_no> and <port2_no>).
'H11' ... 'H22'
–
H matrix elements, referenced to the <LoadPort>
(irrespective of the values of <SourcePort> and <LoadPort>);
see above.
'Q11' ... 'Q22 ', 'PREL'
–
9-term correction factors, for internal
use (combine with <SourcePort> = 1, <LoadPort> is ignored).
'L1', 'L2', 'LA'
–
9-term correction factors, for internal use only
(combine with <SourcePort> = 1, <LoadPort> = 2).
Range:
The error terms are dimensionless complex num-
bers.
