Agilent / HP / Keysight 8901B

The Agilent / HP 8901B Modulation Analyzer combines four precise measurement functions into unit.

The Agilent / HP 8901B is fully automatic, HP-IB programmable instrument which includes a power meter, modulation analyzer, frequency counter, and audio analyzer.

The Agilent / HP 8901B Modulation Analyzer provides the performance you need, the features you want, and the reliability and serviceability you expect for precise signal analysis.

The Agilent / HP 8901B with the HP 11722A Sensor Module measures power from +30 dBm to -20 dBm at frequencies from 100 kHz to 2.6 GHz. The HP 8901B accepts all HP 8480 series power sensors for extended measurement capability.

The 8901B modulation analyzer offers 1% accuracy for AM, FM (3% accuracy for Phase Modulation) and fast one-key operation. The HP 8901B has extremely low internal noise, and very low Amplitude Modulation/Phase Modulation and Phase Modulation /Amplitude Modulation conversion, for accurately measuring residual and incidental AM, FM and Phase Modulation on a wide range of simple and complex modulated signals.

RF Frequency of complex modulated signals can be difficult to measure, but not with the HP 8901B.

The Agilent / HP 8901B includes many features designed for transmitter testing, such as a Peak Hold detector for capturing short transient modulation signals and a special Tone-Burst-Receiver Mode.

The 8901B modulation analyzer may be directly connected to the output of the transmitter, overpower protection to 25 watts is standard.

The HP 8901B's built-in power meter eliminates the need for an external power meter. Unlike diode detectors, the HP 8901B's power meter accurately measures signals with harmonics and spurious.

The 8901B modulation analyzer is an important component of automatic RF test systems. All functions of 8901B such as power measurement, frequency count, modulation, and audio analysis are fully automatic and easily programmed.

Because of its precision modulation and power measurements, The Agilent 8901B is a valuable tool for calibrating automatic test systems.

The HP 8901B Modulation Analyzer counts all types of modulated signals with 10 Hz resolution. The high stability reference option has an aging rate of less than 1X10^-9/day.

The HP 8901B's audio capabilities often eliminate the need for external equipment when measuring demodulated signals or external audio signals. The Analyzer counts audio frequencies with 6 digits of resolution, measures distortion of 400 Hz and 1000 Hz signals and measures rms levels from 100 mV to 3V with 4% accuracy.

The HP 8901B is very easy to use. In automatic operation, all major functions are selected with a single key. No manual tuning or range selection is needed. The front panel is simple, uncluttered, and easy to use.

With a single key stroke the Agilent / HP 8901B automatically senses the power sensor type, autoranges to the input signal, measures its power, compensates for sensor flatness, and displays the results in units you choose.

The Agilent / HP 8901B provides Store and recall feature with which instrument settings can be stored in eight non-volatile memory locations.
