1 Introduction Three-Port Test Set The HP 8753E Option H39 is a modied HP 8753E network analyzer that adds a third test port to the HP 8753E test set. The test ports allow measurement applications for three-port devices with the ability to make S-parameter measurements between any two test ports. This user's guide provides information on how to operate the HP 8753E Option H39 using I/O commands and HP{IB commands, as well as examples of how to implement the commands. Further information on how to control the HP 8753E can be found in the HP 8753E User's and Service Guide. Refer to the \Reference Material" in Chapter 2 for the part number of the HP 8753E User's and Service Guide. This user's guide also provides the specications for the HP 8753E Option H39. Note Test port 1 and test port 3 are the instrument's default ports: on preset or when power is turned on, port 1 and port 3 are active. The port status is indicated by an LED status light located to the right of each test port. Three states are indicated by the LED status light: Bright: Indicates the source (incident) port. Dim: Indicates the receive (through) port. O: Indicates the port is inactive. For further information on the status indicators, refer to the \Front Panel Features" section in this Chapter 2 of this user's guide, and the \Theory of Operation and Troubleshooting" section in the HP 8753E Option H39 Service Guide.

Note Test Port LEDs: The LED to the right of each test port indicates the status of that port. The LEDs show which ports are active, which is providing the source of the RF power, and which port is inactive. The LEDs are lit to indicate which ports are active. The inactive port LED is not lit. The brightest LED indicates the port supplying the RF source. The dim LED indicates the receiver port. The following shows the LED status at preset or power up. 1. Port 1 LED is bright. 2. Port 2 LED is o. 3. Port 3 LED is dim. Operation 2-3

When the network analyzer is in the dual-channel mode and the channels are uncoupled, the test set I/O (FWD and REV) can be set dierently regardless of the FWD and REV I/O setting. Only the S11, S21, S12, and S22 parameters are displayed on the network analyzer. Refer to \Example 2: Duplexer Setup" in this chapter for more information. Caution Before performing a full 2-port calibration, make sure that both the TESTSET I/O FWD and the TESTSET I/O REV settings are set the same. Operation 2-5

Operation 2-11

Operator's Check Description The operator's check consists of two softkey-initiated tests: Port 1 Op Chk and Port 2 Op Chk. A short is connected to port 1 (port 2, port 3) to reect all the source energy back into the analyzer for an S 11 (S 22 ) measurement. The rst part of Port 1, Op Chk checks the repeatability of the transfer switch. An S 11 measurement is stored in memory and the switch is toggled to port 3 and then back to port 1 where another S 11 measurement is made. The dierence between the memory trace and the second trace is switch repeatability. The remaining parts of both tests exercise the internal attenuator in 5 db steps over a 55 db range. The resulting measurements must be within a limit testing window to pass the test. The window size is based on source and receiver specications. The operator's check determines the following: The source is phase locked across the entire frequency range. All three samplers are functioning properly. All transfer switches and receiver switches are operational. The attenuator steps 5 db at a time.

2 System Verification and Performance Tests There are two ways to conrm that the HP 8753E Option H39 network analyzer is able to make measurements as specied by Hewlett-Packard. Both ways are described in this chapter. The rst way is through the system verication procedure. With system verication, the performance of the network analyzer is conrmed as a complete measurement system. The network analyzer is used to measure the traceable behavior of test devices that are part of a verication kit. All the measurement uncertainties of the network analyzer, taken as a measurement system, have been accounted for in the serialized data disk shipped with the verication kit. The second way to conrm the specied performance of the network analyzer is by using the series of performance tests described in this chapter. Successful completion of an individual test conrms the specied performance of the specic subsystem tested, such as the source or receiver. Successful completion of the whole series of performance tests conrms the specied performance of the network analyzer as a complete measurement system. For a complete description of the verication and performance test process refer to the HP 8753E Service Guide. System Verification and Performance Tests 2-1

How to Test the Performance of Your Analyzer To obtain the same quality of performance testing that Hewlett-Packard has administered at the factory, you must perform one of the following: OR the system verication procedure all of the performance test procedures. This quality of performance testing guarantees that the analyzer is performing within all of the published specications. Hewlett-Packard will issue a Certicate of Calibration for your analyzer if the following conditions are met: 1. The performance verication tests are performed by personnel qualied by Hewlett-Packard. 2. Your analyzer passes all the performed tests. 3. The equipment and standards that you used to perform the tests are traceable to a national standards institute. Note If you have a particular type of measurement application that does not use all of the analyzer's measurement capabilities, you may ask your local Hewlett-Packard service center for a subset of specications that you want veried. However, this does create a potential for making incorrect measurements, if you use a dierent application than what was specied. Performance Test Record Find and use the appropriate \Performance Test Record" in the following subchapters of this guide: Performance Test Record for 30 khz to 3 GHz Performance Test Record for 30 khz to 6 GHz 2-2 System Verification and Performance Tests

General Instrument Setup Information In the verication procedure, the HP 8753E Option H39 is set up using Type-N (m) to APC-7 adapters. The adapters are installed on ports 1 and 3. Cables are then connected to the adapters. This setup is used throughout the verication procedure. Calibration of the instrument is done with the adapters and cables attached. If the cables are removed, the calibration will be aected and the performance of the instrument will be invalid. All connections to ports 1 and 3 are done at the open end of the cable. The analyzer will be set up to use the turn-on and preset default ports (port 1 and port 3). System verication of the HP 8753E Option H39 requires less setup, by leaving the adapters and cables on the analyzer, and utilizing the default settings. Note Once calibration is completed with the adapters and cables attached to the analyzer, the adapters and cables should remain on the analyzer until all of the verication procedure has been completed. If the adapters or cables are removed the calibration is aected and the performance of the instrument will be invalid. System Verification Cycle and Kit Recertification Hewlett-Packard recommends that you verify your network analyzer measurement system every six months. Hewlett-Packard also suggests that you get your verication kit recertied annually. Refer to the HP 85029B 7-mm Verication Kit Operating and Service Manual for more information. Check to see how the verication kit's oppy disk is labeled: If your verication disk is labeled HP 8753D Verification Data Disk, or HP 8753D & HP 8753E Verification Data Disk, you may proceed with the system verication. If your verication disk is not labeled as indicated above, you may send your HP 85029B 7-mm verication kit to the nearest service center for recertication, which includes a data disk that you can use with the HP 8753E.
