Television Parallel-to-Serial Converter. This section contains the following

information:

 Product Description

 Options and Accessories

 Installation

Product Description

The PSC 1125 Digital Television Parallel-to-Serial Converter converts digital

television parallel signals to digital television serial digital signals which comply

with BTA S-004A (SMPTE 292M). Because the converter accepts output signals

from the Tektronix TSG1001 Multi-format Test Signal Generator, you can

generate a digital television signal by using the converter in combination with the

generator.

. To assure proper operation of your converter, your TSG1001 Multi-format

Test Signal Generator must have a serial number of B040000 or above, or it must

be upgraded to the B040000 level with the field upgrade kit part number

040-1526-00.

Installation

This section provides instructions for installing the converter. Refer to the

Specifications section for details about the appropriate installation environment.

 Do not install the instrument in a place where ambient temperature

may go over 40C (104F).

For proper ventilation, the instrument requires a clearance of 6 inches at the

front and rear. The cooling air goes in through the front vent holes and out

through the rear panel vent holes. Restricting the air flow can lead to an

excessive internal temperature. Before starting operation, make sure that nothing

blocks the vent holes.

The converter operates from a single-phase power source with the neutral

conductor at or near earth ground. The line conductor is fused for over-current

protection. A protective ground connection through the grounding conductor in

the power cord is essential for safe operation.

 The instrument does not have a power-switch. When you connect the

power cable to the AC line connector, the instrument powers on.

AC Power Requirements. The converter operates from an AC line frequency of 50

or 60 Hz, over the range of 100 to 240 V. The typical power draw is

20 VA (approximately 20 Watts). Refer to the Specifications section for addition-

al information on power and environmental requirements.

Connecting Cable. Connect the power cable to the instrument first, and then

connect it to the AC voltage line. Note that connecting the power cable causes

the instrument to power on.

After connecting the power, make sure that the fan on the rear panel is working.

If the fan is not working, turn off the power by disconnecting the power cable

from the AC voltage line and contact Tektronix for servicing.

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

. 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.

Downloading Signal

Libraries

Getting Started

PSC 1125 Digital Television Parallel-to-Serial Converter Instruction Manual



An example for downloading the signal libraries follows:

To download the signal libraries from a PC to the TSG1001, you should install

the SDP1000 communication utility, COM1000, into the PC. If the necessary

communication utility is not already stored in the directory, sdp1000, refer to the

TSG1001 and SDP1000 product documentation.

. For details on installation of the COM1000, the SDP1000 communication

utility, and downloading the signal set data to the TSG1001, refer to the manuals

supplied with the TSG1001 and SDP1000.

1. Connect the TSG1001 and PC using the parallel interface cable that is

supplied with the TSG1001. On the PC, type:

2. Insert the signal library floppy disk into the floppy disk drive on the PC.

Type:

 

The screen for the libraries appears.



3. Select one of the files. For example, select the 1125_59 (HDTV/SMPTE

274M 59.94 Hz) signal set file which provides SMPTE 274M data with

BT.709 colorimetry and 59.94 Hz field rate. Then press:
