 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
reference 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 H
21
= 1.

The analyzer provides a default calibration corresponding to a test setup which does
not introduce any systematic errors; see

Types
Device-specific, command or query
After a system error correction in one of the sweep types Power, Time, or CW
Mode, the query returns two sets of correction data, corresponding to the fixed CW
frequency and the CW frequency plus 1 Hz (minus 1 Hz if the CW frequency is equal
to the maximum frequency of the analyzer).
Example:
See [SENSe<Ch>:]CORRection:COLLect:SAVE:DEFault.
The different calibration types of the analyzer provide the following error terms:
