2 Testing Performance c Press Type:; then, turn the Entry knob to select Average - Full Screen, and press Add Measurement. 4 Read the “current” average voltage value as V1. 5 Use the BNC tee and cables to connect the oscilloscope calibrator /power supply to both the oscilloscope and the multimeter (see Figure 3).
Testing Performance 2 6 Adjust the output so that the multimeter reading displays the first Volts/div calibrator setting value in Table 8 (depending on the oscilloscope model). 7 Disconnect the multimeter. 8 Wait until the measurement settles. 9 Read the “current” average voltage value again as V2. 10 Calculate the difference V2 - V1. The difference in average voltage readings should be within the test limits of Table 8 (depending on the oscilloscope model).
2 Testing Performance Use a Blocking Capacitor to Reduce Noise On the more sensitive ranges, such as 1 mV/div, 2 mV/div, and 5 mV/div, noise may be a factor. To eliminate the noise, add a BNC Tee, blocking capacitor, and shorting cap at the oscilloscope channel input to shunt the noise to ground. See Figure 4. If a BNC capacitor is not available, use an SMA blocking capacitor, adapter, and cap. See “Blocking capacitor and shorting cap” in the equipment list on page 24 for details.
Testing Performance 2 To verify dual cursor accuracy This test verifies the dual cursor accuracy for each analog channel. This test is similar to the test for verifying the DC vertical gain, except you will measure the dc voltage output of an oscilloscope calibrator using dual cursors on the oscilloscope and compare the results with the multimeter reading. Dual cursor accuracy test limits: ±[DC vertical gain accuracy + 0.

Testing Performance 2 8 Press the Y2 softkey, then position the Y2 cursor to the center of the voltage trace using the Entry knob. The ΔY value on the lower line of the display should be within the test limits of Table 10. If a result is not within the test limits, go to the “Troubleshooting” chapter. Then return here. 9 Disconnect the oscilloscope calibrator from the oscilloscope. 10 Repeat this procedure to check the dual cursor accuracy with the remaining Volts/div setting values in Table 10.
2 Testing Performance Use a Blocking Capacitor to Reduce Noise On the more sensitive ranges, such as 1 mV/div, 2 mV/div, and 5 mV/div, noise may be a factor. To eliminate the noise, add a BNC Tee, blocking capacitor, and shorting cap at the oscilloscope channel input to shunt the noise to ground. See Figure 6. If a BNC capacitor is not available, use an SMA blocking capacitor, adapter, and cap. See “Blocking capacitor and shorting cap” in the equipment list on page 24 for details.

It is recommended you run Hardware Self Test: • After experiencing abnormal operation. • For additional information to better describe an oscilloscope failure. • To verify proper operation after the oscilloscope has been repaired.
Troubleshooting 4 To verify default setup The oscilloscope is designed to turn on with the setup from the last turn on or previous setup. To recall the default setup: 1 Press the [Default Setup] key. This returns the oscilloscope to its default settings and places the oscilloscope in a known operating condition. The major default settings are: • Horizontal: • main mode. • 100 us/div scale. • 0 s delay. • center time reference. • Vertical: • Channel 1 on. • 5 V/div scale. • dc coupling. • 0 V position.
4 Troubleshooting • Other: • Acquire mode normal. • Run/Stop to Run. • cursor measurements off. Figure 12 Default setup screen 2 If your screen looks substantially different, replace the system board. To perform an Auto Scale on the Probe Comp signal 1 Press the [Default Setup] key. The oscilloscope is now configured to its default settings. 2 Connect an oscilloscope probe from channel 1 to the Probe Comp signal terminal on the front panel.
Troubleshooting 4 4 Press [AutoScale]. 5 You should see a waveform on the oscilloscope’s display similar to this: If you see the waveform, but the square wave is not shaped correctly as shown above, perform the procedure “To compensate passive probes” on page 80. If you do not see the waveform, ensure your power source is adequate, the oscilloscope is properly powered- on, and the probe is connected securely to the front- panel analog channel input BNC and to the Demo 2 (Probe Comp) terminal.
4 Troubleshooting To compensate passive probes You should compensate your passive probes to match their characteristics to the oscilloscope’s channels. A poorly compensated probe can introduce measurement errors. 1 Perform the procedure “To perform an Auto Scale on the Probe Comp signal” on page 78 2 Press the channel key to which the probe is connected ([1], [2], etc.). 3 In the Channel Menu, press Probe. 4 In the Channel Probe Menu, press Probe Check; then, follow the instructions on- screen.
Troubleshooting 4 6 Repeat the procedure for each channel. The process of compensating the probes serves as a basic test to verify that the oscilloscope is functional.
4 Troubleshooting Troubleshooting Internal Assemblies The service policy for all bandwidth model oscilloscopes is assembly level replacement. You can use the procedures described in this section to help identify assemblies that need replacement. Generally, you want to make sure cables to the assembly are good and properly seated. Then, you check that the assembly is supplied with the proper power.
Troubleshooting 4 To prepare for internal assembly troubleshooting WA R N I N G WA R N I N G CAUTION CAUTION HAZARDOUS VOLTAGES EXIST — REMOVE POWER FIRST ! The procedures described in this section are performed with power supplied to the oscilloscope and with the protective covers removed. Only trained service personnel who are aware of the hazards involved should perform the procedures. Whenever possible, perform the procedures with the power cord removed from the oscilloscope.
4 Troubleshooting fan power cable connected as shown in the following figure. Figure 14 CAUTION Setup for troubleshooting internal assemblies MAKE SURE EARTH GROUND IS MAINTAINED FOR THE FRONT DECK ! For example, connect a cable with alligator clips between the rear deck chassis and the front deck chassis, or connect a BNC cable from one of the BNCs on the system board to a known grounded BNC on your workbench.
Troubleshooting CAUTION 4 USE AN EXTERNAL FAN TO AVOID OVERHEATING COMPONENTS ! When you remove the oscilloscope cover and main shield, use an external fan to provide continuous air flow over the heat sinks. Air flow over the heat sinks is reduced when the cover and main shield are removed, which leads to higher than normal operating temperatures. Have the fan blow air across the system board where the heat sinks are located. Otherwise, damage to the components can occur.
4 Troubleshooting Flowchart for Internal Assembly Power Troubleshooting The following flowchart is a simplified overview of troubleshooting power to the oscilloscope’s internal assemblies.
Troubleshooting 4 System Board Drawings Use these drawings to locate test points on the oscilloscope system board.
4 Troubleshooting Figure 16 88 System Board Test Points/Connectors - Top Side, Right 4000 X-Series Oscilloscopes Service Guide
Troubleshooting 4 To check the system board power supply test points This procedure checks the power supply test points on the system board (see See Figure 16 on page 88). Values outside the expected range help identify bad assemblies. 1 Follow the instructions in “To prepare for internal assembly troubleshooting” on page 83. 2 Connect the negative lead of the multimeter to a ground point on the oscilloscope. 3 Connect the power cord, and turn on the oscilloscope.
4 Troubleshooting 5 Next, check the supplies coming from the system board: Test Point (near J3700) Expected Value Assemblies Supplied VP5V (+5V) +5 V ±3% Keyboard, Indicates supply coming from System Board system board is good. Replace the system board. VP12V (+12V) +12 V ±3% System Board Replace the system board. VP1V8 (+1.8V) +1.8 V ±3% System Board Replace the system board. VP1V4 (+1.4V) +1.4 V ±3% System Board Replace the system board.
Troubleshooting 4 To check the line filter board AC output When the 13 V bulk power is not being properly supplied, this procedure tests the AC input to the power supply to determine whether there is a problem with the line filter board. 1 Follow the instructions in “To prepare for internal assembly troubleshooting” on page 83. 2 Connect the power cord, and turn on the oscilloscope.
4 Troubleshooting • If there is no AC power at J1 of the power supply, there is something wrong with the AC mains section of the line filter assembly, and you need to replace the line filter assembly. • If there is AC power at J1 of the power supply, but the instrument still will not power ON when the power switch (S101) is in the ON position, go to “To check the power switch” on page 92.
Troubleshooting Figure 18 4 Verify power switch operation • With S101 in the OFF position (switch contacts closed) you should measure less than 1 ohm of resistance. • With S101 in the ON position (switch contacts open) you should measure infinite resistance. If you do not measure these two values, there is something wrong with the power switch (S101 on the line filter assembly), and you need to replace the line filter assembly.
4 Troubleshooting To check the power supply DC output This procedure checks the power supply DC output after verifying the AC input is good and checking the power switch operation. 1 Follow the instructions in “To prepare for internal assembly troubleshooting” on page 83. 2 Connect the negative lead of the multimeter to a ground point on the oscilloscope. 3 With the power cord disconnected: a Disconnect the DC supply cable that is plugged into J3700 of the system board.
Troubleshooting 4 To check the display supplies This procedure checks the display supply voltages on the system board test points when the display backlight power cable and the display cable are disconnected. If one or both of these voltages are bad when the cables are connected but good when the cables are disconnected, it indicates problems with the display assembly. 1 Follow the instructions in “To prepare for internal assembly troubleshooting” on page 83.
4 Troubleshooting Test Point (near J2000) Expected Value Assemblies Supplied If Good If Bad VP3V3 (+3.3V) +3.3 V ±3% LCD, System Board If good when the display cable is disconnected from the system board, but bad when the display cable is connected, this indicates a problem with either the display cable or the display assembly, 1 Turn off the oscilloscope, and disconnect the power cord. 2 Replace the display cable. 3 Connect the power cord, and turn on the oscilloscope.
Troubleshooting 4 5 Check the keyboard supplies: Test Point (near J4303) Expected Value Assemblies Supplied If Good VP5V (+5V) +5 V ±3% VP13V_PRB (+13V_PRB) +13 V ±3% VM15V_PRB (-15V_PRB) -13.2 V ±4% VP7V5_PRB (+7.5_PRB) +6.28 V ±4% VM7V5_PRB (-7.5_PRB) -6.
4 Troubleshooting 5 If the fan voltage is approximately +9 Vdc at room temperature, replace the fan. If the fan voltage is not approximately +9 Vdc, replace the system board. The proper voltage range depending on temperature is between +7.9 Vdc to +12.8 Vdc.
