6.5.7 Complex Corrections

This dialog is used to set up and display information about the Complex Corrections

set. It also lets you view and edit certain information such as the Description and

Comment for the selected Complex Correction.

Complex Corrections (loaded from .s2p files) support both magnitude and phase

corrections, whereas standard corrections (loaded from standard Ampcor .csv

files) support only magnitude corrections.

When loading an .s2p file, the component representing S21 is the one that is used

to generate the complex correction. If no S21 component is present, a Mass Storage

error is reported.

NOTE

Data types RI, MA, and DB are supported.

The phase components of the S2P file are taken to be in degrees, not in radians.

You must provide the phase correction in degrees.

Unlike Correction files, S2P files describe device characteristics, rather than the

correction required to compensate for those characteristics; so, when an S2P file

is loaded, both the magnitude and phase are negated to turn it into a correction

Complex Corrections and standard corrections can be turned on at the same time.

For example, you could turn on Correction 2, Correction 4, and Complex Correction

1 and 2, all at the same time. The magnitude part of all the corrections would add,

and the phase part of the complex corrections would add.

You can have up to 64 Complex Corrections loaded simultaneously. Each Complex

Correction can hold up to 30,000 points.

You can load a standard correction into Complex Corrections, but it will only provide

a magnitude correction, not a phase correction.

NOTE

A standard correction (from a CSV file) can be loaded into a Complex Correction,

but when it is loaded the Phase correction is set to 0 for all points.

Some measurements, like Swept SA, have no phase component to the

measurement, but nonetheless support Complex Corrections. For such

measurements, only the Magnitude part of the Complex Correction is applied.
