Hewlett Packard 853A
Spectrum Analyzer Display/Mainframe, Refurbished

Digital Display

The 853A is a digital display mainframe for use with the 8557A, 8558B, and the 8559A spectrum analyzer plug-ins. 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 (available via the front panel).

HP-IB Capability Includes Direct Plotter Control

A hard-copy record of the displayed traces and graticule can be made on a digital plotter via the HP-IB by simply using the 853A's front panel pushbuttons; a controller is not required.  Although analyzer controls are not programmable, some HP-IB applications include using a controller for recording trace data or for operator prompts on the 853A CRT.  The digital display and processing functions can be remotely programmed, and analyzer sweeps can be initiated via HP-IB.

Two Configurations

The display is offered in two styles.  The 853A is a ruggedized, portable mainframe complete with tilt-bail handle and drip proof, protective front cover.  The 853A is ideally suited for rugged, field service environments and any areas where system mobility is required.  The 853A Option 001 offers the digital display in a full module bench or rack mount configuration.
