Description

The HP 8720A provides simple and complete vector network mea-surements in a compact and fully integrated microwave network ana-lyzer. Characterize your microwave components and networks accurately, yet economically with the HP 8720A microwave network analyzer. Integration of the 130 MHz to 20 GHz swept synthesized source, test set, and receiver results in a compact, low cost network analyzer which is ideal for incoming inspection, production, and final test measurements. With two independent display channels available, you can simulta-neously measure the reflection and transmissions characteristics of the device under test. The easy-to-use softkey selection of measure-ment functions allows you to quickly measure the magnitude, phase, or group delay characteristics of your device under test. Directly mea-sure the electrical length of a single device or phase match multiple devices. Data can be displayed in log magnitude, linear magnitude, SWR, phase, group delay, polar, real, or Smith Chart formats. The HP 8720A’s integrated synthesized source provides 100 kHz frequency resolution standard or, with the addition of option 001, it will provide 1 Hz frequency resolution for testing narrowband, fre-quency selective or electrically long devices. The integrated synthe-sized source also provides a measurement port power level of —10 to —65 dBm which is settable in 5 dB steps.

Time Domain Analysis

The HP 8720A with option 010 has the capability of displaying the time domain response of a network, obtained by computing the In-verse Fourier Transform of the frequency domain response. The time domain response displays the reflection coefficient versus time, yield-ing the magnitude and location of each individual discontinuity of the network. It can also display the transmission coefficient versus time, yielding simulated transient response analysis of the network.

Features Designed for Manufacturing

The HP 8720A’s productivity features allow increased throughput on your production floor. The arbitrary frequency list mode allows selection of only those frequencies you wish to test, resulting in re-duced test time. In this mode, you can define up to 30 CW frequencies or swept frequency segments, calibrate once, and then measure all of the segments or “zoom-in” on just one segment and still remain cali-brated. The HP 8720A’s limit test capability allows your technicians to make pass/fail decisions easily and systematically. Based on the specifications for the device under test, define up to 22 test limits on each channel so your technicians can align and objectively verify the device’s response. Utilize the HP 8720A’s save/recall capability to reduce set up time and enable all your technicians to repeatedly use the same test configuration. This feature allows your engineer or skilled specialist to define the test configuration once, store it to an external CS80 compatible disc drive, and then have it recalled by each member of your production test line without the use of an exter-nal computer. This feature provides confidence that each technician is aligning and evaluating your devices under the same conditions. For a permanent record of your measurement results, the HP 8720A’s copy feature allows the entire CRT display to be directly output to a com-patible HP-GL plotter or printer. All of the functions of the HP 8720A are completely program-mable from an external computer through the Hewlett-Packard In-terface Bus. For fully automated, guided measurements, use the HP 85162A Measurement Automation Software. To completely and effi-ciently characterize crystals, SAWs, and other resonant devices, use the HP 85165A Resonator Measurement Software.
