Getting Started  
Test Set Description  
Test Set Description  
The HP 8517B test set configured with an HP 8510B/C network analyzer  
and an HP 8360 series source, creates a system capable of making  
S-parameter measurements from 45 MHz to 50 GHz. The system is  
particularly suited for making two-port device measurements. You can  
measure all four S-parameters without physically reversing the DUT (device  
under test).  
The system is also designed for making measurements on non-reciprocal  
devices or components like transistors, amplifiers or isolators where S  
measurements are required.  
12  
Two directional couplers are used for signal separation. The configuration is  
illustrated in the following figures:  
• Figure 1-1, “Standard HP 8517B Test Set Block Diagram"  
• Figure 1-2, “Option 004, HP 8517B Test Set Block Diagram"  
• Figure 1-3, “Option 007, HP 8517B Test Set Block Diagram"  
For active-device measurements, two bias tees apply external DC bias to  
both test port center conductors.

Verifying Test Set Operation  
Verifying Test Set Operation  
The test set is designed to operate with an HP 8510C network analyzer. You  
can verify its operation by:  
Table 1-2 Test Set Operation Verification  
Checking System Operation  
Checking Specifications  
Perform a system calibration as described in the HP 8510C Operating and  
Programming Manual. A successful calibration indicates that the system, and  
therefore the test set, are operating properly.  
Specifications for the test set, and the system, can be determined by running  
the specification and performance verification software described in the HP  
8510C On-Site Service Manual, Chapter 8, “Specification and Performance  
Verification”. Additional mechanical specifications and supplemental  
characteristics are in Chapter 4, “Specifications” of this manual.  
Troubleshooting the Test Set  
To troubleshoot the test set, refer to the HP 8510C On-Site Service Manual.  
Use the information in that manual to determine if the test set is at fault. If the  
test set is at fault, refer to Chapter 5, “Troubleshooting the Test Set” in this  
manual to isolate the trouble.

Maintaining Measurement Accuracy  
Maintaining Measurement Accuracy  
Precision measurements rely on a precision calibration of the network  
analyzer. As a general rule, the shorter the time lapse between a calibration  
and a device measurement, the more precise the measurement results will be  
(within the limitations of your system).  
Hewlett-Packard recommends calibrating your system every few hours, or at  
least re-verifying your system’s calibration this frequently. Doing so helps  
retain measurement precision.  
The frequency of calibrations is determined by both the location of the  
system and the ambient temperature stability in its operating area.
