In this page, the OPEN/SHORT/LOAD correction for correcting the stray admittance
and residual impedances can be performed.
The correction function has two kinds of correction methods. In one method the open
and short correction can be performed at all of the frequency points using the
interpolation method, and in the other method the open, short, and load correction can
be performed at the frequency points you specify.
In <CORRECTION> page, you can configure each of the following controls with the
cursor placed in the corresponding field.
Open correction [OPEN]
Short correction [SHORT]
Load correction [LOAD]
Frequency 1, 2, 3 for OPEN, SHORT, LOAD Correction [FREQ 1] [FREQ 2]
[FREQ3]

The AT281x’s OPEN correction capability cancels errors due to the stray admittance (G,
B) in parallel with the device under test (Refer to Figure 5-3)
Figure5‐3 StrayAdmittance
The OPEN correction data is taken at all preset frequency points, independent of the test
frequency you set. Refer to Table 4-10, Table 4-11, Table 4-12 and Table 4-13. (Page 24)
