Hewlett-Packard 853A+8559A

The HP853A is a digital display mainframe for the use with the HP8557A/8558B/8559A plug-ins. Signals are displayed on either of two independently stored digital traces. Display processing capabilities include MAX HOLD, DIGITAL AVERAGING, and TRACE NORMALIZATION for extended measurement capability. The HP853A is ideally suited for rugged, field service environments and any areas where system mobility is required. Its HP-IB capability includes direct plotter control. The HP8559A plug-in covers the frequency range of 10MHz to 21GHz in six bands. Sensitivity is -111dBm and max input signal is +30dBm. Resolution bandwidth is from 1KHz to 3MHz in a 1 - 3 sequence. Bandwidth and frequency span are independently variable or may be coupled for optimum display when control markers are aligned.
