After performing a calibration with a user defined calibration kit, all log magnitude data is displayed as -200 dB; why?

-200 dB is a display limitation of the analyzer. This most often indicates some form of a data overflow processing error (i.e. division by zero, etc.). This error can be caused by several anomalies. One cause could be improperly defined calibration standards. Examples of improperly defined calibration standards: "None" is selected for a STD type instead of "Open", "Short", "Load", "Delay/Thru" or "Arbitrary". Another cause could be that "Ps" is entered rather than "pS" for pico seconds in the delay field. See image below.
