Section 1
Section 1 Performance Check and Calibration Procedures This section consists of two separate procedures. The first, a Performance Check, is used to determine compliance with the Performance Requirements in the Specification. The Performance Check is followed by a Calibration Procedure, which provides adjustment instructions intended to return the instrument to its original operating performance following repairs or a routine maintenance program.
Performance Check and Calibration Procedures 2. Test Oscilloscope Vertical Amplifier: 30 MHz Bandwidth, 1 mV Sensitivity. Time Base: 10 ns/div to 5 ms/div sweep speeds, triggering to 5 MHz. For example: a TEKTRONIX TAS 465 Oscilloscope. Also 10X probes, P6106 (Tektronix Part No. 010–6106–03), and a 1X probe, P6101 (Tektronix Part No. 010–6101–03). 3. Television Signal Generator To provide color test signals for the television standards which will be tested.
Performance Check and Calibration Procedures 7. Frequency Counter Range: 10 Hz to 135 MHz. Accuracy: "0.001%. Ratio architecture. For example: Tektronix DC5009 installed in a TM5000-Series Power Module. 8. Video Amplitude Calibrator Signal, adjustable square wave 0.0 to 999.9 mV p–p with a resolution of 0.1 mV and an accuracy of 0.05%; frequency approximately 270 Hz. For example: TEKTRONIX 067–0916–00 in a TM5000-Series Power Module. 9.
