PSC 1125 Digital Television Parallel-to-Serial Converter Instruction Manual
The TSG1001 signal library floppy disk (Tektronix part number 063-2986-XX)
is supplied with the converter. This disk contains the following items:
SMPTE 260M/274M/296M download files which comply with the SDP1000
V2.3 or above
Special tools to let the TSG1001 generate signals which comply with
SMPTE 260M/274M/296M
See Table 1–2 for descriptions of the signals on the disk.

. The Zone Plate signal set is available on the TSG1001 and is independent
of the DNL signal set that is loaded into the TSG1001 RAM.
Press the Signal Set button to select the Zone Plate signal. Select RAM Board to
re-select the signal set in the DNL file that was downloaded.
The Zone Plate signal is a digital Luminance or Y channel signal for sinusoidal
evaluation of multidimensional spectral response and is converted to serial-digi-
tal by the converter. However, the Cr/Cb or color-difference signals are not at
digital black and this signal does not convert to a proper digital/analog RGB
signal.
Upon conversion of the Y signal to analog, you can evaluate the picture monitor
response by looping the Y signal through all three RGB inputs or by not
connecting the Pb/Pr signals to a picture monitor with Y/Pb/Pr inputs.
Note also that the Y, Pb, Pr buttons on the TSG1001 front panel selectively blank
the digital signal outputs to a value close to, but not equal to, digital black.
To generate the necessary signal, you must download the signal set data supplied
with the floppy disk to the TSG1001. Refer to the SDP1000 user manual for
details on how to download to the TSG1001.
