....by the accuracy of the signal analyzer that is used to characterize the multitone generator. In this article, a broadband sampling oscilloscope (HP 54121T) is used as a signal analyzer, such that the accuracy of the calibration is traceable to the so called nose to nose calibration procedure [6]. II. HARDWARE IMPLEMENTATION OF A VNNA The VNNA hardware has three major parts. A first part is the signal generation. Depending on the application, the signal generators must be capable of generating multitone signals. A second part of the VNNA is the test set. This test set directs the ....

....on the availability of a multitone reference generator. This reference generator is characterized by an accurate broadband signal analyzer. As signal analyzer a broadband sampling oscilloscope (HP 54121T) is being used, which means that the calibration is traceable to a nose tonose procedure [6]. The calibration procedure that was developed will be explained in what follows. The calibration is based on the assumption that the 4 digitized wave quantities are linearly related with the 4 physical waves at the device ports (for each port, an input wave and an output wave is measured) ....

....excitation signals. One promising application of this development is a nonlinear network analyzer. Calibration of such a measurement device requires that the amplitude and phase relationship between the different harmonics be known. A primary, lab calibration technique has been described in [1]. Once this is accomplished, subsequent calibrations can be done with a calibrated broadband source. The signal of this source should be stable, should contain enough harmonics in the band of interest and should be measured Manuscript received September 8, 1993; revised February 7,1994.

....during the calibration procedure. Further, the input network model fully includes the effects of mismatch reflections, and we use the model to reconcile nose to nose waveform correction methods with traditional signal power measurement techniques. I. INTRODUCTION The nose to nose calibration [1] provides an estimate for the response of a broadband oscilloscope and the means to deconvolve that response from a measured signal. The calibration provides one of the only means of obtaining total phase relations of the frequency components in a broadband signal (up to 50 GHz) Certain ....

....of obtaining total phase relations of the frequency components in a broadband signal (up to 50 GHz) Certain conditions that are not usually required in traditional calibrations must be met for the nose to nose method to work. While many of these conditions have been studied in previous works [1 3], the first section of this paper examines the requirement of identical forward and reverse transfer functions for the internal interconnection networks. The second section uses this understanding to develop an equivalence between oscilloscope based measurements of signal power and traditional ....

....This generator is used as a reference standard for phase calibration in a similar way as a powermeter is used for the amplitude calibration. Relationships between the phase of harmonics are initially determined using a sampling oscilloscope calibrated using the so called nose tonose procedure [14].
