Performance Verification Two types of Performance Verification procedures can be performed on this product: Brief Procedures and Performance Tests. You may not need to perform all of these procedures, depending on what you want to accomplish. To rapidly confirm that the instrument functions and was adjusted properly, just do the brief procedures under Self Tests.
Performance Verification Conventions Throughout these procedures the following conventions apply: Each test procedure uses the following general format: Title of Test Equipment Required Prerequisites Procedure Each procedure consists of as many steps, substeps, and subparts as required to do the test. Steps, substeps, and subparts are sequenced as follows: 1.
Performance Verification Figure 2-1: Toolbar and menu bar (< 4 GHz models shown) The procedures assume you have connected a mouse to the instrument so you can click on the screen controls. If you have not connected a mouse, you can use the touch screen to operate the screen controls.
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 instrument functions properly.
Brief Procedures 1. Verify that internal diagnostics pass: Do the following substeps to verify passing of internal diagnostics. a. Display the System diagnostics menu: If the instrument is in toolbar mode, put the instrument into menu bar mode. Pull down the Utilities menu and select Instrument Diagnostics..This displays the diagnostics control window.
Brief Procedures Therefore, when the instructions in the functional tests that follow call for you to verify that a signal appears on-screen "that is about five divisions in amplitude" or "has a period of about six horizontal divisions," etc., do NOT interpret the quantities given as limits.
Brief Procedures 3. Turn off all channels: If any of the front-panel channel buttons are lighted, push those buttons to turn off the displayed channels as shown in the following figure. Figure 2-3: Channel button location 4. Select the channel to test: Push the channel button for the channel you are currently testing.
Brief Procedures 6. Verify that the channel is operational: Confirm that the following statements are true. Verify that the vertical scale readout and the waveform amplitude for the channel under test. (See Table 2-1.) Table 2-1: Vertical settings < 4 GHz models ≥...
Page 73
Brief Procedures Acquisition tab in the control window that displays. Click each of the acquisition modes and confirm that the following statements are true. Sample mode displays an actively acquiring waveform on-screen. (Note that there is a small amount of noise present on the square wave). Peak Detect mode displays an actively acquiring waveform on-screen with the noise present in Sample mode "peak detected".
Brief Procedures Figure 2-4: Setup for time base test 3. Set up the instrument: Push the front panel Autoset button. 4. Set the Vertical Scale to 200 mV per division. 5. Set the time base: Set the horizontal Scale to 200 μs/div. The time-base readout is displayed at the bottom of the graticule.
Page 75
Brief Procedures 7. Verify horizontal delay: a. Center a rising edge on screen: Set the horizontal Position knob so that the rising edge where the waveform is triggered is lined up with the center horizontal graticule. Change the horizontal Scale to 20 μs/div. The rising edge of the waveform should remain near the center graticule and the falling edge should be off screen.
Brief Procedures Verify the A (Main) and B Equipment required Prerequisites (Delayed) Trigger Systems < 4 GHz models: One precision 50 Ω coaxial None cable (Item 4) < 4 GHz models: One BNC to Minigrabber adapter (item 18) ≥ 4 GHz models: One SMA cable (item 21) ≥...
Page 77
Brief Procedures 6. Verify that the delayed trigger system operates: a. Set up the delayed trigger: Pull down the Trig menu and select A – B Trigger Sequence..This displays the A →B Sequence tab of the trigger setup control window. Click the Trig After Time button under A Then B.
Brief Procedures Figure 2-6: Setup for the file system test 3. Set up the instrument: Push the front panel Autoset button. 4. Set the Vertical Scale to 200 mV per division. 5. Set the time base: Set the horizontal Scale to 1 ms/div. The time-base readout is displayed at the bottom of the graticule.
Brief Procedures Verify the Digital Channels Equipment required Prerequisites (MSO70000 Series Only) MSO70000 models: One precision 50 Ω coaxial None cable (item 4) MSO70000 models: One probe tip adapter (item 30) MSO70000 models: One SMA adapter (item 17) MSO70000 models: One logic probe (item 31) 1.

Brief Procedures 5. Press the D0 button. 6. Double click Global Threshold. Use the keypad to enter 200 mV. Press the Apply button. 7. Pull down the Vertical menu and select Vertical Setup. 8. Press Digital input iCapture. 9. From the Digital Source list select D0. 10.
Page 81
Brief Procedures 18. Verify that the displayed position of channel 1 moves lower on the display. 19. Rotate the Vertical Position knob clockwise, back to its original setting. 20. Pull down the Digital menu and select Digital Setup. 21. Double click the D0 Position and enter -1.66 and press Enter. 22.
