Tips for More Accurate Measurement

Tips for More Accurate Measurement
You can use the following techniques to increase measurement accuracy.

Setting measurement time to 8

Set the measurement time to 8, which provides better measurement accuracy.
For the setup procedure, refer to

Selecting an appropriate measurement range

When making a measurement in the fixed range mode, select the
measurement range so that measurement is performed within the
recommended range (refer to
page 10-170
For the setup procedure, refer to

Using the correction functions

The OPEN correction eliminates the error due to the parallel stray admittance
of the measurement cable and test fixture.
The SHORT correction eliminates the error due to the series residual
impedance of the measurement cable and test fixture.
The LOAD correction eliminates the complex error due to the amplitude/phase
error of the measurement cable and test fixture, scanner, and so on.

Making stable measurement

In a high-noise measurement environment, you can obtain more reliable
measurement results by performing averaging.
For the setup procedure, refer to

Making measurements using a four-terminal pair

You can use four-terminal pair measurement to eliminate measurement errors.
