<blockquote> | |||
The 067-1011-00 Digital Sweep Generator (DSG) is designed to support the Performance Check and Adjustment procedures of the Tektronix [[1900|1900 Digital Test Signal Generator]]. | |||
The Digital Sweep Generator provides a 10-bit digital data signal to drive the 1900 digital-to-analog converter (DAC) or any other video DAC compatible with the proposed SMPTE standard ("Digital Video Format for a Parallel Interface (System M/NTSC), July, 1979) digital video interface, generating a swept-frequency sinewave test signal. | |||
[...] | |||
The Digital Sweep Generator provides 10-bit, 14.31818 MHz (Mega samples per second) word data derived from a cosine lookup table stored in three PROMs. | |||
To generate digital data representing a 55.9 kHz sinewave, all 256 words stored in the PROMs are used. | |||
