Nominal Traits This subsection contains a collection of tables that list the various nominal traits that describe the TAS 455 and TAS 465 Analog Oscilloscopes. Included are electrical and mechanical traits. Nominal traits are described using simple statements of fact such as Two, both identical" for the trait Number of Input Channels," rather than in terms of limits that are performance requirements.

Troubleshooting This procedure assumes that there is front panel control. Measure the power supply voltages on J67 on the A1 Analog board. Pin 12 +15V Pin 10 +8.6V Pin 9 -8.6V Pin 6 +5.2V Pin 1 -5.2V Are the voltages approximately the same as the nominal value? No Turn the power off. Remove the cable at J67 on the A1 Analog board and check pins 12, 10, 9, 6, and 1 for shorts to ground. Yes No No Perform the A3 Display Driver Board Troubleshooting Procedure. Yes Replace the A1 Analog board.
