These latest versions are ideal for precise measurements aimed at improving the performance of wireless equipment and signal sources, as well as improving phase noise, which is key to upgrading the measurement resolution of microwave and mm-Wave radar and sensors.
With the demand for high-quality graphics and video in applications such as mobile and satellite/broadcast communications, achieving faster radio communications depends on utilizing wider bandwidth radio signals, with a trend toward the use of microwave and mmWave bands that offer much broader frequency spectrum options. Ensuring wideband radio signals and low error rates in the microwave and mmWave bands requires the use of high dynamic range transmitters, which necessitates high dynamic range measuring instruments to optimize designs.
The NFR (Noise Floor Reduction) option suppresses up to 11 dB of the measured internal noise level of the measurement system, reducing the displayed noise floor level and supporting more accurate measurement of very low-level signals than previously possible. Additionally, the new 2dB Step Attenuator option allows for attenuation from 0 to 60 dB in 2 dB steps across the entire frequency range for the 44.5 GHz model, compared to a standard specification of 0 to 60 dB attenuation in 10 dB steps. This option improves the measurement dynamic range by optimizing the mixer's input level, even at high frequencies.
These latter options are especially useful for measuring broadband signals and microwave and mmWave signals that require measurement of spectrum emissions, leakage power from adjacent channels, and high dynamic range signals in Tx ON and OFF.
There are four models of the MS2840A signal analyzer with different maximum measurement frequencies: 3.6, 6, 26.5, and 44.5 GHz. The 26.5 and 44.5 GHz models can be expanded to cover a measurement frequency range up to 325 GHz by connecting an external mixer. Due to its high performance, the MS2840A is widely used in the development and manufacturing of narrowband radio equipment, radio oscillator modules, wireless backhaul, satellite communications, radar, and other applications.
