Operation steps of open correction function
1) On <MEAS DISP> page, press the key [CLEAR], the following soft keys will
be displayed:
SPOT OPEN
SWEEP OPEN
OPEN OFF ON
MORE 1/2
2) Connect test fixture to test terminal. The fixture is open and not connecting to
any DUT.
3) Press SPOT OPEN, U2836 will make open correction on the current
frequency.
4) Press SWEEP OPEN, U2836 will test the open admittance (capacitance and
inductance) under 37 frequencies. It will take about 20 seconds to finish the
open full-frequency correction. In the process of correction , the following
soft key will be displayed:
CANCEL
This soft key can be used to terminate the current open correction operation
and reserve the formal open correction data.
5) Press OPEN OFF ON to turn ON/OFF the function of open-circuit correction,
If ON, U2836 will perform open-circuit correction calculation in the later
testing process. If OFF, no open correction calculation will be taken in later
measurement.
3.4.2 SHORT
The short correction function of U2836 can eliminate the error caused by spurious
inductance (R, X) in serial with DUT as shown in figure 3-2.
