. 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 Cb/Cr 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 defeat the
digital signal outputs but do not set them to digital black.
To load the signal set data into the TSG1001 generator, you should install the
SDP1000 communication utility, COM1000, onto a PC. If the necessary
communication utility is not already stored in the directory, SDP1000, refer to
the TSG1001 and SDP1000 product documentation.
. For the details on installing the COM1000, installing the SDP1000
communication utility, and downloading the signal set data to the TSG1001
generator, refer to the manuals supplied with the TSG1001 generator and the
SDP1000 package.
1. Connect the TSG1001 generator and PC with a parallel interface cable. On
the PC, type:
