Preface Related Manuals This is the Performance Verification for the TDS 410A, TDS 4204, and TDS 460A Oscilloscopes, It contains procedures suitable for determining if the oscilloscope functions, is adjusted properly, and meets the performance characteristics as warranted. Also contained in this document are the specifications for the TDS 400A Digitizing Oscilloscopes. The following documents relate to the use or service of the digitizing oscilloscope.
Performance Verification Procedures Two types of Perform an Verification procedures an 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 (hat this oscilloscope functions and is adjusted properly, just do the procedures under Self Tests, which begin on page 1-5.
Performance Ve 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 and sub steps as required to do the test. Steps and sub steps are sequenced as follows: 1. First Step a. First Sub step b, Second Subside 2.
Brief Procedures Self Tests Verify Internal Adjustment, Self Compensation, and Diagnostics 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 Tess use the probe-adjust output at the front panel as a test signal source for further verifying that the oscilloscope functions properly. A standard-accessory probe, included with this oscilloscope, is the only equipment required.
Brief Procedures Caspian the CAL menu. 1-6 e, Confirm the four adjustment sections have passed swats: ® Press SHIFT; then press UTILITY. #® Press the main men bunion System until Cal is highlighted in the pop-up menu. ® Verify that the word Pass appears in the main menu under the following men labels: Voltage Reference, High Frequency Response, Low Frequency Response, and Trigger Skew. (See Figure 1-2.) Tek Run: 1.
Brief Procedures You must run an SPC anytime you wish to ensure that the measurements you wake are made with the most accuracy possible. You should also run an §PC if the temperature has changed more than 5° C since the last SPC was performed. . Run the signal path compensation: Disconnect all input signals. Press the main-menu button Signal Path; then press the side-menu bunion OK Compensate Signal Paths, NOTE.
