5.9 Error correction

FRA 51602

5.9.3 Equalizing

This function corrects for errors of externally connected cables and probes, etc.

The method of correcting for systematic error is explained with the connection example shown in

Figure

5-18

Figure 5-18

Example of connections for gain-phase measurement

The set up and measurement procedure is described below.

1) Set the measurement conditions, including the sweep frequency range, measurement range, and

oscillator amplitude, etc.

2) Set

[EQUALIZING]

[OFF]

3) Remove the equipment under test (EUT) and connect the input and output.

Example of connections for systematic error

4) Turn the oscillator output on and perform a sweep measurement under the same conditions as when

measuring the EUT.
