An Open/Short/Load calibration set is a set of calibration standards used to verify and optimize the performance of a network analyzer or other test equipment. The set typically consists of three standards: an open (Open), a short (Short), and a load (Load) standard

The open standard consists of a terminal with the end disconnected

The short standard consists of a terminal where the end is shorted

The load resistor standard consists of connection where the end is connected to a 50 ohm terminator capable of terminating the impedance of the cable

By using these standards, the network analyzer can correct the parameters of the test setup and improve the measurement accuracy. If the calibration kit is not used, measurements may be inaccurate due to reflections and distortion of the signal as it passes along cables or other equipment

This OSL kit combines all three standards in a compact form

The connectors are designed as N connectors (male)
