Using QuickCal with a Long Jumper Cable
QuickCal requires a sufficient frequency span to adequately characterize the
jumper cable (the cable between the instrument port and the DUT). If a 'Cal
Failed' error appears and you connected the optional Load standard, then
increase the frequency span of the measurement until the error no longer
appears. After the calibration, you can then decrease the frequency span as
needed and rely on interpolation. Learn more about Interpolation in
"Interpolation" on page
QuickCal is also limited in how much jumper cable loss it can tolerate. If
QuickCal without the Load is failing, then measure the Load during the
QuickCal to see if that resolves the issue.

O, S, L Cal

An OPEN, SHORT, LOAD Cal is performed using discrete standards from a Cal
Kit. Several Cal Kit definitions are built into the FieldFox firmware.

supported Cal Kits. Also at this website, download Data-Link software that
allows you to edit Cal Kit definitions or add a new Cal Kit.
O, S, L Cal are extremely accurate when performed using the correct Cal Kits
with standards that are clean and in good repair, and when using correct
connection procedures.
