Electrical Instrument ExamplePerformance Requirements
NOTE: The 1410 Series generators with standard SPG and TSG modules can be used, but this will not allow all checks and
adjustments to be made.
The 1410 and 1411 Option AB are mainframes with modified TSG7 and TSG11 Color Bar Generators that more accurately control
output amplitudes of the standard 75% amplitude bars.
When preparing this procedure, the modules were configured to provide the following signals at the mainframe J1 to J6 rear-panel
connectors:
J1 Black Burst
J2 Color Bars
J3 Switcher
J4 Linearity
J5 Pulse & Bar
J6 Multiburst
When performing linear waveform distortion, differential phase, and gain checks, the signal from the module was connected
directly to the instrument instead of going through the Switcher.
3. Television Generator Provides accurate test signals for
checking SCH Phase accuracy.
Required signals: Color Bar, Black Burst,
and Field 1 Reference.
TEKTRONIX TSG-170A NTSC Television
Generator or TEKTRONIX TSG-271 PAL
Television Generator.
4. Leveled Sine Wave Generator Flatness 1%, 250 kHz to 50 MHz. The
flatness can be characterized (a chart
made of variations) with the TEKTRONIX
Peak-to-Peak Detector (015-0408-00).
TEKTRONIX SG503 Leveled Sine Wave
Generator installed in a TEKTRONIX
