Keysight / Agilent 8720C Microwave Network Analyzer, 50 MHz to 20 GHz

Keysight / Agilent 8720C Microwave Network Analyzer, 50 MHz to 20 GHz

The 8720C is a high-performance microwave network analyzer for measurements of reflection and transmission parameters. The HP 8720C covers the frequency range of 50 MHz to 20 GHz. Frequency resolution is 100 kHz (standard) or 1 Hz (option 001). The 8720C 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 using 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 improve performance and provide 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 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.

8720C Options (Included):

Option 001 1 Hz Frequency Resolution
Devices with narrow frequency spans (such as crystal or notch filters) require better frequency resolution than the 100 kHz provided by the standard instrument. Option 001 provides 1 Hz frequency resolution for finer control of start, stop, and marker frequencies.

Option 010, Time Domain
Option 010 can display the time-domain response of a network by computing the inverse Fourier transform of the frequency-domain response. This allows the response of a test device to be seen as a function of time or distance. Displaying the reflection coefficient of a network versus time determines the magnitude and location of each discontinuity. Displaying the transmission coefficient determines the characteristics of individual transmission paths. Time-domain operations retain the calibration that is active in the frequency domain. The time-domain capability is useful for designing and characterizing devices such as SAW filters, SAW delay lines, and RF cables.
