3 Theory of Operation and Troubleshooting
Theory of Operation and Troubleshooting This chapter provides basic theory of operation and troubleshooting information for the analyzer. This information is intended to be used as a guide in finding and correcting possible problems that could be experienced with Option H39. Component locations, cable diagrams, and other aides are supplied in this section of the service guide. If the information provided is not enough to remedy the problem, refer to your standard documentation.
Theory of Operation and Troubleshooting Theory of Operation Theory of Operation Three-Port Test Set The 8753ES Option H39 includes a three-port signal-separation test set that routes signals from any two ports to the A and B receiver channel samplers. Refer to Figure 3-12 on page 3-25 and Figure 3-13 on page 3-26 for the component locations and RF paths. Option H39 adds a third test port to the standard 8753ES test set.
Theory of Operation and Troubleshooting Theory of Operation LED Front Panel The front panel LEDs indicate whether the test port is the incident port, the receiver port, or the inactive port. The test port LED that is the brightest is the incident port. The test port LED that is dim is the receiver port. The test port LED that is off is the inactive port where no signal separation is taking place.
Theory of Operation and Troubleshooting Theory of Operation Test Set Interface The test set interface board provides biasing for active devices under test with an external dc voltage. Only Port 1 can provide bias. Bias supplied to Port 1 is applied directly to the center conductor pin. In addition, the test set interface board provides the drive signals for all internal solid-state switches.
Theory of Operation and Troubleshooting Troubleshooting Troubleshooting This section only covers troubleshooting techniques for the three-port test set with the 3PORT mode off. To turn the 3PORT mode off, press System, CONFIGURE MENU, OPTION HXX CONFIG, 3PORT MODE and toggle to OFF. For information on troubleshooting other portions of the analyzer, refer to the standard documentation.
Theory of Operation and Troubleshooting Troubleshooting Source Test This source troubleshooting section tests the functionality of the test port(s) in question. 1. Connect the equipment as shown in Figure 3-1. Figure 3-1 Source Test Setup 2. Press Preset, Sweep Setup, CW FREQ. The default frequency is 1 GHz. 3. To measure Port 1, make sure the analyzer is in a forward state by pressing: • Preset, Meas, REFL: FWD S11 (A/R) or • Seq, TTL I/O, TTL OUT, TESTSET I/O FWD, toggle to 7. 4.
Theory of Operation and Troubleshooting Troubleshooting 8. To measure Port 2 in the reverse state, press Preset, Meas, REFL: REV S22 (A/R). 9. Make a note of the reading on the power meter. 10. Press Meas, REFL: REV S22 (B/R). 11. Press Seq, TTL I/O, TTL OUT, TESTSET I/O REV, 5, x1. 12. Make a note of the reading on the power meter. 13. To measure Port 3, make sure the analyzer is in a reverse state and set the TESTSET I/O REV to 7. 14. Move the power sensor to Port 3. 15. Press Meas, REFL: REV S33 (B/R) .
Theory of Operation and Troubleshooting Troubleshooting Symptom 2: No RF Source at Port 1 Check the bias connection to the switch S0 (see Figure 3-13) and the J3 connections (see Figure 3-17) on the test set interface board. If the bias connector is loose, reconnect it. If the bias connector is firmly in place in the J3 connector, check the bias voltages on the switch S0 (+0.62 Vdc and +16.3 Vdc). The center bias pin on S0 should be approximately 22 V. 1.
Theory of Operation and Troubleshooting Troubleshooting If the LEDs are working on Port 1 and Port 3 and the bias voltage is still incorrect on switch S0, move the S1 bias connector from J6 to J3 (see Figure 3-17) on the test set interface board. Press Seq, TTL I/O, TTL OUT, TESTSET I/O FWD, 6, x1, I/O REV, 6, x1. Check the bias voltage (+0.62 Vdc and + 16.3 Vdc) on S1 (see Figure 3-13). Toggle the instrument between the REFL: FWD S11 (A/R) and REFL: REV S22 (B/R) states.
Theory of Operation and Troubleshooting Troubleshooting The voltage on bias pins 1 and 2 should alternate between +0.62 Vdc and +16.3 Vdc when the instrument is toggled from REFL: FWD S11 (A/R) and REFL: REV S22 (B/R). If the bias voltage changes state but there is still no RF at Port 2 in the forward state or no RF at Port 3 in the reverse state, the transfer switch S1 may need to be replaced.
Theory of Operation and Troubleshooting Troubleshooting Port 3 Test Connect the analyzer as shown in Figure 3-2.
Theory of Operation and Troubleshooting Troubleshooting 1. Press Preset, Meas, Start, 300, k/m, INPUT PORTS, B, TESTPORT 1. 2. If there is a power hole or roll off in the response, check the RF cables. Refer to Figure 3-14, Figure 3-15, and Figure 3-16 for cable locations. If no response is seen for channel B, check the bias connection to switch S2 (see Figure 3-13) and the J5 connection (see Figure 3-17) on the test set interface board. If the connector is loose, reconnect it.
Theory of Operation and Troubleshooting Troubleshooting When the instrument is toggled from Port 1 to Port 3 and from Port 1 to Port 2, the bright LED should remain on Port 1. If the LEDs are working on Port 1 to Port 3 and Port 1 to Port 2, and the bias voltage is still incorrect on switch S2, remove the J5 bias connector (see Figure 3-17) from the test set interface board and move the S4 bias connector from J14 to J5 on the test set interface board.
