Operation Check

Operation Check

This section describes the operation check method. Be sure to perform the

operation check after each time a part is replaced.

Open Impedance Check

Conduct an Open impedance check with the fixture set for the OPEN state.

Necessary

equipment

— Shorting bars (supplied as accessories)
— Impedance measuring instrument (calibrated at the 7-mm connector end)

Step 1.

Prepare a measuring instrument calibrated at the 7-mm connector end.

Connect the test fixture with this instrument.

Step 2.

Set the fixture for the OPEN state, at the DUT measuring position (see

Figure

3-18 on page 38

Step 3.

Make the settings for the 4291B as follows.

Step 4.

Under these conditions, measure Cp at 100 MHz and 1 GHz separately.

Step 5.

Confirm that the Cp value is within the typical range shown in Table 6-5.

If a measuring instrument other than the 4291B is to be used, make the equivalent

settings according to the Operation and Service Manual for the instrument to be

used.
