following fixed frequency points. In addition to the following frequency points, based on the
short-circuit correction data at the following frequency points, the instrument can calculate all short
correction data of different test ranges which corresponds to all test frequencies by using the
interpolation calculation method. Move the cursor to the Short field, and use the softkey MEAS
Short to execute the full frequency short correction. The fixed frequency point is the same as the
open correction.
Operation steps of short-circuit correction function:
The short-circuit correction includes the full-frequency short-circuit correction using the insertion
calculation method and the single-frequency short-circuit correction for the set frequency point.
Perform the following steps to perform short-circuit correction at full frequency using the insertion
calculation method. For details on single-frequency short-circuit correction, please refer to the
"Load Correction" operating instructions.
Move the cursor to the short-circuit setting field, and the following soft keys are displayed in the
soft key area of the screen.
Turn off the short correction function. The
calculation of short correction will no longer be
performed in the subsequent measurement process.
Make the short correction valid and the short
correction calculation will be performed in the
subsequent test process. If the frequency settings
are all OFF, the open correction calculation uses
the short correction data of the current frequency
calculated by the interpolation method. If the
frequency is set to ON, and the current test
frequency is equal to the corresponding frequency,
the short correction data of the corresponding
frequency will be used for the calculation of short
correction.
Connect the test fixture to the test terminal of the
instrument. Short the test fixture with a
short-circuit strip. Press the soft key Meas short,
and the short-circuit parasitic impedance (resistance
and reactance) at the above fixed frequency point
will be measured. It takes about 75 seconds for the
short-circuit full-frequency correction. During the
short-circuit full-frequency correction process, the
following soft keys are displayed on the screen.
The short-circuit resistance measurement of the DC
resistance function will be performed.
