Patent number: 8022687Abstract: The invention relates to a method for measuring objects for measurement, by means of a network analyzer with several measurement ports, at least one signal generator, for stimulating the object for measurement and at least one local oscillator, for measurement of the signal transmitted or reflected from the object for measurement by the superposition principle. According to the invention, on a frequency change, only the frequency of the local oscillator or the frequency of the signal generator is changed but not the frequency of the local oscillator and the signal generator simultaneously.Type: GrantFiled: January 5, 2007Date of Patent: September 20, 2011Assignee: Rohde & Schwarz GmbH & Co.

Patent number: 7948326Abstract: The invention relates to a method for carrying out a frequency change whilst retaining the phase relationship between several devices, in particular, network analyzers. Each device has at least one signal generator for stimulating an object for measurement and at least one local oscillator, connected to at least one mixer, for receiving a measuring signal obtained from the object for measurement by the superposition principle. On changing frequency, in a first step, only the frequency of the local oscillators of all devices is changed and the frequency of the signal generators of all devices remains unchanged. In a second step, only the frequency of at least one signal generator is changed and the frequency of the local oscillators of all devices remains unchanged.Type: GrantFiled: January 5, 2007Date of Patent: May 24, 2011Assignee: Rohde & Schwarz GmbH & Co.

Patent number: 7772928Abstract: An apparatus for the phase synchronization of several devices, wherein one device is the master device and the other devices are slave devices, with a phase synchronization unit for every device, each of which has: a first controlled oscillator for producing a master reference signal, a first phase detector which, in order to control the first oscillator, compares the phase of a first comparison signal derived from the master reference signal with the phase of a second comparison signal derived from an auxiliary reference signal if the device is itself the master device and a second phase detector which, in order to control the first oscillator, compares the phase of a third comparison signal derived from the master reference signal with the phase of a reference signal coming from the phase synchronization unit of the master device if the device is not itself the master device but a slave device.Type: GrantFiled: January 4, 2007Date of Patent: August 10, 2010Assignee: Rohde & Schwarz GmbH & Co.

Patent number: 7313492Abstract: A method and a device for increasing the dynamic range and measuring accuracy of a measuring device for spectrum and/or network analysis images a high-frequency electronic signal within a frequency range into at least two spectra through a first frequency translation by means of a mixer of the measuring device. As a result of the first frequency translation, the spectrum of the high-frequency electronic signal is successively imaged within the resolution bandwidth (?FZF) of an intermediate frequency filter of the measuring device. At the same time, through a second frequency translation, every spectral line of interference signals generated in the measuring device comes to be disposed outside the resolution bandwidth (?FZF) of the intermediate frequency filter.Type: GrantFiled: April 4, 2005Date of Patent: December 25, 2007Assignee: Rohde & Schwarz GmbH & Co.

Patent number: 6628172Abstract: A digital compensation filtering technique is provided that enables indirect phase locked loop modulation with a digital modulation data stream having a bandwidth that exceeds, perhaps by an order of magnitude, the bandwidth characteristic of the phase locked loop. A modulation data receiver is provided for receiving from a modulation source digital input modulation data having a bandwidth that exceeds the cutoff frequency characteristic of the phase locked loop frequency response. A digital processor is coupled to the modulation data receiver for digitally processing the input modulation data to amplify modulation data at frequencies higher than the phase locked loop cutoff frequency.Type: GrantFiled: January 10, 2002Date of Patent: September 30, 2003Assignee: Rhode & Schwarz GmbH & Co.
