HP / Agilent 8559A

The 8559A is a 0.01 to 21 GHz spectrum analyzer plug-in for use with both the 853A and 180-series display. The high performance and conveneient operation of this economical unit is ideally suited for a variety of applications in production, R&D or field service environments.

Simple 3-Knob Operation

Preset the 8559A to the color coded, ¿basic operation¿ settings, and use the coupled controls to make most measurements in three easy steps. Tune to the signal; the LED readout displays its frequency. Zoom-in on the signal by reducing the span width; the resolution bandwidth, video filter, and sweep time automatically change to an optimum value for a calibrated display. Then, change the reference level to bring the peak of the signal to the top of the screen for the
most accurate amplitude measurement. A signal identifier is available in all bands to provide assurance of correct measurements.

Absolute Amplitude Calibration

Signal levels can be read directly in dBm from the CRT without the use of external standards or calculations. The signal level represented by the top CRT graticule line is always indicated by the reference level control, and vertical scale factors of 10 dB/Div, 1 dB/Div, or linear can be selected.

853A Spectrum Analyzer Digital Display (Sold Separately)

The 853A is a digital display mainframe for use with the 8559A spectrum analyzer plug-in. Signals are displayed on either of two independently stored digital traces. Display processing capabilities include maximum hold, digital averaging, and trace normalization for extended measurement capability. A built-in microprocessor manages the display operation and provides access to built-in test routines for display calibration and test (accessible via the front panel).
