The HP 8719A and 8720B are high performance microwave network analyzers for measurements of reflection and transmission parameters. The 8719A covers the frequency range of 130 MHz to 13.5 GHz. The 8720B reaches 20 GHz. Frequency resolution is 100 kHz (standard) or 1 Hz with option 001. Each instrument integrates a synthesized source, a switching S-parameter test set, and a dual channel receiver to measure and display magnitude, phase, and group delay of transmitted and reflected power. Option 010 provides the capability of transforming measured data from the frequency domain to the time domain.

Digital signal processing and microprocessor controls combine to provide easy operation and measurement improvement. Measurement functions are selected with front panel keys and softkey menus. Two independent display channels and a large screen color CRT display the measurement results of one or both channels, in logarithmic, linear, or Smith chart display formats.

Trace math, data averaging, trace smoothing, electrical delay, and accuracy enhancement provide performance improvement and flexibility. Accuracy enhancement reduces the effects of repeatable measurement variations in the test system. Displayed measurement results can be printed or plotted directly to a compatible peripheral without the use of an external computer. Instrument states can be saved in internal memory for at least three days without line power to the instrument. In addition, each analyzer can control a compatible disk drive for external storage capability. Built-in service diagnostics are available to simplify troubleshooting procedures.

The analyzer is equipped with the HP-IB interface.
