The 16197A’s electrode spaces are 0.5 mm, 1 mm, 1.5 mm and 2 mm and the device
guide matches these spaces with appropriate insertion holes for the applicable SMD.
The 0.2 mm electrode spacing is available with option 001, which includes a device
guide with 0603 mm/0201inch insertion holes, an electrode plate and 4 shorting
devices.
Compensation and measurement: First of all, select the appropriate device insertion
hole. If the device insertion hole is not positioned in the pressure arm’s contact range,
reposition the device guide and the electrode plate. Once this is prepared, perform
compensation. Open and short compensations are recommended in combination with
the electrical length compensation before measurement. The fixture’s electrical length
must be entered into the electrical length compensation function of the measurement

instrument first. Next, open compensation is performed by not placing anything in the
device insertion hole. Short compensation is performed by placing the furnished shorting
device in the device insertion hole. After performing open and short compensations in
combination with the electrical length compensation, the DUT is inserted into the device
insertion hole. Once the measurement of the DUT is complete, remove the DUT from the
fixture. The following figures show how compensation and measurement is performed.
