algorithm and single frequency open correction on 201 frequencies. Execute the
following operation steps to make open correction. The single frequency open
correction can refer to “Load correction”
1) Move the cursor to OPEN, the following soft keys will be displayed:
ON
OFF
MEAS OPEN
DCR OPEN
2) Connect test fixture to test terminal. The fixture is open and not connecting to
any DUT.
3) Press MEAS OPEN, TH2829C will test the open admittance (capacitance and
inductance) under 48 frequencies. It will take about 75 seconds to finish the
open full-frequency correction. In the process of correction , the following
soft key will be displayed:
ABORT
This soft key can be used to terminate the current open correction operation
and reserve the formal open correction data.
4) Press DCR OPEN, TH2829X will test the open-circuit resistance under the DC
resistance function.
5) Press ON to turn on the function of open-circuit correction, then TH2829X will
perform open-circuit correction calculation in the later testing process. IF
FREQ 1~ FREQ 201 are set as OFF, the open-circuit correction data of the
current frequency will be calculated by imbedding algorithm. When FREQ 1 ~
FREQ 201 are set as ON, the value of the current test frequency will be that
of FREQ 1, FREQ 2 or FREQ 201, in this case, the open correction data of FREQ
1, FREQ 2 or FREQ 201 will be used to the calculation of open correction.
6) Press OFF to turn off the open correction function. In later measurement, no
open correction calculation will be taken.
3.7.2 SHORT
The short correction function of TH2829X can eliminate the error caused by
spurious inductance (R, X) in serial with DUT as shown in figure 3-2.
Figure 3-2 Spurious Inductance
TH2829X adopts two kinds of short correction data.
