A method for determining scattering parameters using a calibration substrate having at least one calibration standard with at least two electrical connection points, each for one measurement gate of a vector network analyzer. At least one electrical connection point is formed of at least one calibration standard having a switch, wherein the switch has a first electrical contact electrically connected to an electrical connection point of the calibration standard, a second electrical contact designed for electrically connecting to a measurement gate of the vector network analyzer, and a third electrical contact, wherein the switch is designed such that an electrical contact is established either between the first and third electrical contact or between the first and second electrical contact.

It is an object of the present invention to provide a high-quality printed image in a printing machine. To achieve this, a method for adjusting a fusing deviceof a digital printing machine has been provided, in which case microwave signals of a specific frequency or frequency range are directed at a printing material, a change between the microwave signals reflected by the printing material and the emitted microwave signals is detected, and in which case the fusing device is adjusted based on the change between said microwave signals. Furthermore, a measuring devicefor a printing machine is provided, said device preferably being used for carrying out the said method, whereby the measuring device is configured so as to detect a change between a microwave signal reflected by the printing materialand a microwave signal directed at said printing material.
