Abstract: A phase reference system for a phase-sensitive receiver is shown that provides an output signal which can be used for phase calibration of a frequency-converting device under test. The phase reference system has a first frequency generator that generates a first generator signal with a first generator frequency fg1 and a second frequency generator that generates a second generator signal with a second generator frequency fg2. The first and second generator signals are fed to a multiplier. The multiplier process the signals and outputs first, second and third spectral line data.

Abstract: A non-transitory computer-readable storage medium has computer-readable data portions stored thereon, the data portions including configuration data items relating to configurable parameters of a frequency converter.

Abstract: A method for calibrating a network analyzer having at least two test ports is described in which a completely known, transmitting first calibration standard, is designed as a two-port standard and is connected between two test ports of the network analyzer, is measured. Also measured is a second calibration standard that is designed as a two-port standard or a double one-port standard and is connected between the same test ports of the network analyzer, of which only the reflection parameters are known. Measured too is a third calibration standard, symmetrical with regard to its reflection parameters and designed as a two-port standard or a double one-port standard and is connected between the same test ports of the network analyzer. From results of these measurements, the matrix elements of error two-ports assigned to the test ports are calculated.
