    Theory of Operation This section describes the electrical operation of the oscilloscope. Figure 9- -1 on page 9- -2 shows the module interconnections. Logic Conventions The oscilloscope contains many digital logic circuits. This manual refers to these circuits with standard logic symbols and terms. Unless otherwise stated, all logic functions are described using the positive-logic convention: the more positive of the two logic levels is the high (1) state, and the more negative level is the low (0) state.

    Theory of Operation Processor System. The processor system contains two processor boards with microprocessors that control the entire oscilloscope. The basic configuration supports four input channels labeled Ch1 through Ch 4, provides an external trigger input, a trigger output, a Ch3 signal output, and a probe compensation output.

  • Page 61: Brief Procedures

    Brief Procedures The Self Tests use internal routines to confirm basic functionality and proper adjustment. No test equipment is required to do these test procedures. The Functional Tests utilize the probe-compensation output at the front panel as a test-signal source for further verifying that the oscilloscope functions properly. A BNC cable and a BNC-to-SMA adaptor or a TCA-BNC adapter are required to do these test procedures.

  • Page 62: Functional Tests

    Brief Procedures NOTE. If diagnostic error message 531 is displayed, re-run signal-path com- pensation. d. Verify that no failures are found and reported on-screen. All tests should pass. e.

  • Page 66 8. Verify that the channel is operational: Confirm that the following statements are true. H For TDS6604: The vertical scale readout for the channel under test shows a setting of about 500 mV, and a square-wave probe-compensa- tion signal about 1 division (0.5 divisions if not using a probe) in amplitude (about 460 mV [240 mV if not using a P7260 probe]) is on the screen.

    11. Remove the test hookup: Disconnect the BNC cable, fixture, and the probe from the channel input and the probe compensation output. Verify the Time Base Equipment One BNC cable, such as Tektronix part number 012-0076-00 required One TCA-BNC adapter Prerequisites None 1.
  • Page 68 Brief Procedures H One period of the square-wave probe-compensation signal is about five horizontal divisions on-screen for the 200 s/div horizontal scale setting. H Rotating the horizontal SCALE knob clockwise expands the waveform on the screen (more horizontal divisions per waveform period), counterclockwise rotation contracts it, and returning the horizontal scale to 200 s/div returns the period to about five divisions.
