Not all system connections are shown. 2. In dual source configurations, the second source can be multiplexed in a similar manner. 3.
Measurement Calibration After selecting the active test set, complete the system calibration procedure as usual. When you select a different test set, make sure that you recall the cal set that applies to that test set. NOTE Since the cal-set limited instrument state does not include the number of the active test set, a cal set which does not apply to the current test set can be turned on without displaying the HP 8510C caution messages.
Measuring High-Power Devices with Option 004 The HP 8517B, Option 004 test set enables devices with output power up to 30 dBm (1 watt) to be measured at Port 2, without adding external attenuators. Reverse dynamic range (S12) degrades by approximately 3 dB. When measuring devices having greater than +17 dBm output power, you must use the Port 2 step attenuator to decrease the power to ≤+17 dBm. The step attenuator has to be set during calibration for the value needed during device measurements.
Changing Signal Path States After System Calibration Changing an internal attenuator or any external equipment after completing the calibration means the measurement results cannot be specified. You must use your own estimation of the potential error contribution due to the change. For example, when the port attenuation is changed with correction ON, the message CAUTION: CORRECTION MAY BE INVALID displays.
If you view the response of a short circuit, notice that: • • Changing Port 1 attenuator has negligible effect on S11 marker reading Changing Port 2 attenuator has negligible effect on S22 marker reading This is due to the way the attenuators are paired. Both the reference and the test signal are changed by approximately equal amounts. When viewing S21 or S12, however, changing Port 1 or Port 2 attenuators offsets the marker reading by the difference value between Port 1 attenuator and Port 2 attenuator.
5. View the S21 measurement. If the thru is connected, the transmission coefficient should be 1 ∠0° . 6. Press PARAMETER [S12], then press the following DISPLAY: menu keys: {SELECT DEFAULTS} {DEFAULT to MEMORY: 2} 7. Press PARAMETER [S12] to view the S12 measurement. If the thru is connected, the transmission coefficient should be 1 ∠0° . Normalization is turned OFF for S11 and S22 measurements. Then the appropriate memory is selected and normalization is turned on to view S21 and S12.
Making Operational Checks To check the operation of multiple test-set configurations, do the following: 1. Connect a device with a known response to test set number 1. Press the following HP 8510C front-panel keys: INSTRUMENT STATE [LOCAL] AUXILIARY MENUS [SYSTEM] {HP-IB ADDRESSES} {TEST SET} 2. When the message TEST SET HP-IB ADDRESS appears, enter [20], the address of test set number 1, then press [x1]. The measurement trace from test-set number 1 should display. 3.
Performance Verification Standard system performance verification procedures verify the operation of an Option 001 test set used as test set number 1. To verify the performance of a different test set in the configuration, enter its HP-IB address (as explained in “Making Operational Checks” on page 3-13) to select it, then continue with this procedure. Refer to the HP 8510C On-Site Service Manual for its performance verification procedure.
Using Anti-Rotation Clamps During the performance verification procedure, use anti-rotation clamps to secure RF connections at the test ports of each test set. While installed, each clamp stabilizes the connector on RF cable to the large nut on the test set’s RF test port. If an adapter is used, the clamp stabilizes the adapter to the front panel RF port connector. Without these clamps, the test port connections can loosen when a device under test is moved.
CAUTION Important! The test set RF connector becomes loosened easily. Hold the RF cable securely throughout the remainder of this procedure. Do not allow the cable to rotate. Figure 3-5 Using a Torque Wrench Correctly Positioning the thumb-screw See Figure 3-6. Position the clamp so the thumb-screw is positioned at the top of the clamp. • Turn the clamp to visually align the clamp flats with the flats on the test port connector nut.
NOTE The flats may actually be in any orientation, with respect to the front panel. Figure 3-6 Visually Aligning Clamp and Nut Flats Positioning the connector See Figure 3-7. Maneuver the clamp over the RF connector and onto the test port connector. 1. Hold the test cable with one hand. Use the other hand to press the clamp gently and steadily, as you wiggle it into position straight over the RF connector and onto the test port connector nut.
Operating the HP 8517B Test Set Using Anti-Rotation Clamps Aligning the thumb-screw See Figure 3-8. Ensure that the thumb-screw is aligned with the counter-sink hole on the clamp’s body. 1. Push the clamp toward the test set front panel. 2. Finger-tighten the thumb-screw. The cable cannot be damaged if the thumb-screw is tightened too tightly.

5 Troubleshooting the Test Set The troubleshooting strategy for the HP 8517B S-Parameter test set is a systematic sequence of procedures. The information may be used after system-level troubleshooting has identified the test set as the problem instrument. Use the troubleshooting flowchart in Figure 5-2 to help isolate the faulty assembly. Notice procedure numbers within some of the flow diagram blocks. These are keyed to troubleshooting procedures.
Troubleshooting the Test Set Theory of Operation Theory of Operation RF paths for Port 1 and Port 2 are similar. This section discusses in detail the source power signal, as it is routed via the RF IN connector, through the test set, and to Port 1 for S11 and S21 measurements. Figure 5-1 Standard HP 8517B RF Block Diagram The RF Source Power • RF source power enters the test set through the rear panel. The RF power is applied to the switch/splitter (A18).
Troubleshooting the Test Set Theory of Operation The Reference Signal Path The Test Signal Path The S11 and S21 Measurements The Sampler Control Switching • The reference signal is routed from the switch/splitter through the 20-7 dB tapered pad (AT1) to attenuate any VTO feed-through signals. • The signal is then applied to A10, the a1 sampler assembly, where it is down-converted to a 20 MHz IF (intermediate frequency).
Troubleshooting the Test Set Theory of Operation • The LO Signal Control If the test set is equipped with Option 001 (multiple test set capability), its begin state is inactive. That is, rather than using the test set’s internal IF, a switch is set in the test set to accept an IF from another test set. The LO, generated by A14 VTO/driver, is phase locked to the source so the desired VTO harmonic is 20 MHz greater than the source frequency.
