Anritsu Corporation has released enhanced software functions for its Signal Analyzers MS2830A, MS2840A and MS2850A. These enhancements enable the analyzers to extend the spectrum measurement frequency range to encompass the millimeter-wave band by connecting VDI or Eravant external mixers.
Anritsu’s mid-range benchtop MS2830A, MS2840A, and MS2850A signal analyzers provide high-performance capabilities and comprehensive options for wireless signal measurements across diverse applications. These models span the RF to microwave/millimeter-wave frequency bands and accommodate narrow- to wide-band signals.
For spectrum, signal, and phase-noise measurements, the measurement frequency range can be extended by installing Anritsu’s External Mixer Connection Function MX284090A. This function supports connection of a recommended external mixer from Eravant or VDI to the signal analyzer’s 1st Local Output port.
An image response can occur when measuring with external mixers lacking preselectors to eliminate unwanted signals, causing erroneous reception of signals at different frequencies from the intended signal. Anritsu’s signal analyzers offer intermediate frequencies (IF) of 1.875 GHz (MS2830A) and 1.8755 GHz (MS2840A/MS2850A), facilitating conversion of received high-frequency signals to manageable frequencies for processing. This enables suppression of image-response effects up to 7.5 GHz using Anritsu’s proprietary PS (Preselector Simulation) function, facilitating measurement of hard-to-distinguish variable signals.
The single coaxial-cable connection between the signal analyzer and recommended external mixers enhances flexibility in positioning the signal analyzer and allows the external mixer to be placed close to the device under test.
