This application note demonstrates the use of the Measurement Receiver to calibrate the signal output level of a Signal Generator.Calibration in this application is a two-step process.► The absolute output level of the signal source, at a fixed level, is measured using a thermal power sensor (e.g. NRP50T), which in turn outputs its reading to the FSMR.► Output power calibration over a wider dynamic range (to lower power) is performed by connecting the FSMR to the signal source directly, and sweeping the power of the signal source.The FSMR offers a nominal total measurement uncertainty of <0.015 dB +/- 0.005 dB per 10dB step. At 1GHz, the power measurement range covers -152 dBm to +30 dBm. It is this intrinsic linearity, that the accuracy of the calibration relies upon.Absolute power measurement uncertainty, for the NRP50T thermal power sensor used in this Application Note, is 0.040 dB to 0.143 dB.This process may be repeated at multiple frequencies. Calibration values are automatically stored and managed by the FSMR. Measurement frequencies for calibrations are stored, will be automatically recalled by the FSMR, by re-selection of those frequencies.

Due to the fact that Microsoft does not maintain the Visual Studio .NET 2003 anymore Rohde & Schwarz has to use the successor compiler product Visual Studio .NET 2005 for building the test case packages. All CRTU-G customers having proprietary test case packages, developed based on Visual Studio .NET 2003, can migrate them to Visual Studio .NET 2005. This is required when the proprietary test case packages are going to be enhanced on a platform with installed Visual Studio .NET 2005.

When measuring audio components with unknown transients, the experienced engineer watches the settling of the DUT before accepting a measured result to be valid. The settling function in the UPL/UPD simulates this process and automates it by continuously comparing the measured value with a number of measured values stored before. A measured value is only accepted as being valid if it is within the tolerance limits entered by the user. This application note explains the settling process and gives hints for practical use.

Vector Network Analyzers of the ZVR family measure magnitude and phase of complex S-parameters of a device under test (DUT) in the frequency domain. Using an inverse Fourier transform, the results can be transformed to the time domain. The impulse or step response of the DUT is obtained, which gives an especially clear representation of its characteristics. For instance, faults in cables can be directly localized. Moreover, special time domain filters, so-called gates, can be used to suppress unwanted signal components such as multireflections.
