Agilent / HP / Keysight 89441A

The Agilent/HP 89411A Vector Signal Analyzer covers a frequency range of DC to 2.65MHz.

The Agilent/HP 89411A combines frequency domain and time-domain analysis to provide the most advanced measurements of complex and time-varying signals. Simultaneous time- and frequency-domain measurements and displays improve productivity and enhance ease of use.

The 89411A uses state-of-art digitizing and signal processing technology, these analyzers offer complex signal analysis, such as digital modulation analysis and AM/FM/PM demodulation, vector spectrum analysis, and time-gated spectrum analysis.

The 89411A provides unprecedented speed and power. Complex time and spectrum measurements are made and displayed up to 60 times each second.

Deep time-capture RAM is available with flexible post-processing in time and frequency domains. A variety of display types are available, including log frequency, polar, eye and constellation diagrams.

Multiple signal processors and microprocessors display signal and circuit behavior in real time and produce fast averaged measurements with enhanced signal-to-noise ratio.

The 89411A allows the user to examine only a selected part of the waveform for burst or time-varying signals. Time-selective spectrum analysis in the 89411A allows the entire time-domain signal to be viewed and a specific portion selected for frequency-domain analysis.

The selected data is identified clearly with gate markers and all of its traditional frequency-domain parameters can then be measured.

Optional waterfall and spectrogram display formats take full advantage of the high-measurement and display-update speed. Waterfalls display up to 300 successive spectra and scroll them through the display.

The Agilent 89411A provides a flexible source for circuit stimulation, Sinewaves, periodic chirps, and pseudo-random noise are available, along with user-definable arbitrary waveforms.

A vector baseband mode is also available to provide all of the features and functionality of the 89410A. In vector RF mode, both phase and amplitude characteristics are captured in the time-series data.
