V This report describes the modifications that were made to a Plan View Display (PVD) which allowed it to be switched between the present National Airspace System (NAS) and a future 9020 Replacement (9020R) System. A second PVD was also modified and used to simulate the outputs of the 9020R System. The outputs of the simulated 9020R System were analog X and Y deflection signals, video unblanking, and brightness control bits.

The PVD switch was controlled by a spare switch located on the front panel. The PVD was driven either in the normal manner by the present system or by the remote signals brought in from the 9020R simulator PVD. The R-controls were also switched between two different radar keyboard multiplexer (RKM) output connectors by means of an external relay box controlled by the front panel switch of the PVD.

The switched PVD was driven over cable lengths of 20, 50, 70, and 100 feet. Line width and brightness measurements were taken and display patterns were observed at each of these lengths.

Results were very good up to 70 feet and satisfactory up to 100 feet, 7

INTRODUCTION

BACKGROUND.

Consideration is presently being given to replacing the present National Airspace System (NAS) with a new updated system which will be referred to as the 9020 Replacement (9020R) System. A determination must be made as to what type of displays are to be used with the new system.

PURPOSE.

The purpose of this project was to investigate the possibility of using the Plan View Displays (PVD's) from the present NAS as displays for the 9020R System.

Two possibilities were considered: (1) using the PVD's permanently as simple monitors driven by analog X and Y deflection signals and video unblanking signals from the 9020R System, and (2) switching the PVD's back and forth between the two systems during the initial phase of the 9020R operation without causing system problems. The feasibility of driving the PVD's from the 9020R System over various lengths of cables was also to be determined.

DISCUSSION

Originally, transmitting analog X and Y deflection signals and the Z video signal was considered. This would have eliminated the controller's capability to adjust the brightness levels of various data classes. In order to maintain the present capabilities of the PVD, it was decided to transmit video unblanking signals and three-category enable bits along with the analog X and Y deflection signals.

Two PVD's were modified for this project. The first PVD, which will be referred to as the driver PVD, was modified to provide simulated signal outputs from the 9020R System. This PVD was driven by either the NAS or the En Route Radar Display Recording System (ERDIRS), and it was modified as described below to provide external analog X and Y deflection signals and video unblanking signals. The second PVD, which will be referred to as the switch PVD, was modified to display either the normal data received from the present NAS or the external data received from the 9020R simulator. Data were selected by means of a switch on the front panel of the PVD. The R-control interface was also switched between two output positions of the radar keyboard multiplexor (RKM) at the same time the data were switched, in order to demonstrate the effect on the present NAS. The R-control interface is used for communication between the RKM located in the NAS and the Keyboard, Quick Action Panel, Category and Function Key Panels, and the Radar Position Computer Readout Display (RCRD), which are located in the PVD. A photograph showing the test setup, including the two modified PVD's, the RKM switch box, and test equipment used to make measurements on the PVD's, is shown in figure 1. (A block diagram of the PVD modifications and interconnections is shown in figure A-l. A simplified drawing of the RKM switch is shown in figure A-2.)

SWITCH PVD.

In the switch PVD, it was necessary to open a number of circuit connections on the Video Intensity Control — A2 Printed Circuit Board (PCB) — and on the Signal Pattern Correction — A5 PCB. These connections were rerouted through relays that were then used to switch in the simulated 9020R signals. The relays were mounted directly on the A2 and A3 PCB's. Line receivers, terminators, and input connectors were also mounted on the two PCB's. A spare switch located on the system status control panel of the PVD was wired in and used to control the relays mounted on the PCB's. Figures 2 and 3 show photographs of the two modified PCB's. A photograph of the lower basket of the switch PVD is shown in figure 4. An external box containing relays was connected between the R-control connector of the switch PVD and two RKM output connectors. This RKM switch box was used to switch the PVD R-concrols to the other RKM output connector when the special front panel switch was activated. A photograph of the RKM switch box is shown in figure 5. (Figures A-5 and A-7 show schematics of the unmodified A2 and A5 PCB's. Schematics of the A2 and A5 PCB's, modified for the switch PVD, are shown in figures A-6 and A-8. Figure A-10 shows a schematic drawing of the switch box.)

DRIVER PVD.

In the driver PVD, it was required to output signals from the A2 and the A5 PCB's. No connections on the cards had to be opened. On the A2 PCB, signal points were connected to line drivers that were mounted on the card. The line driver outputs were wired to output connectors that were also mounted directly on the card. On the A5 PCB, the analog X and Y deflection signals were wired to output connectors that were mounted directly on the card. The analog line drivers were mounted on the PVD chassis above the lower basket and connected to the A2 PCB by coaxial cables. Figures 6 and 7 show photographs of the modified PCB's. A photograph of the lower basket of the driver PVD is shown in figure 8. The analog line driver box is located in the upper left corner of the photograph. Figure 9 shows a schematic drawing of the X and Y analog line drivers. (Schematics of the A2 and A5 PCB's, modified for the driver PVD, are shown in figures A-12 and A-13.)

The +5 volt power supply in the switch PVD, and the +5 volt and +15 volt power supplies in the driver PVD were used to provide power for the modifications. These supplies had adequate reserve power to meet the small additional requirements of the modifications.

1 TESTI-NG

The driver PVD and the switch PVD were Located side by side. They were inter- connected by four cables. The analog X and Y deflection signals were transmitted over two 100-ohm coaxial cables. A 75-ohm coaxial cable was used for the character unblanking signal connection. The category enable signals, vector unblanking signal, and character unblank enable signal were transmitted over twisted pair ribbon cable.

Cables of various lengths were used to conduct tests. Cable lengths of 20, 50, 70, and 100 feet were used. At each cable length, the data presented on the switch PVD were observed for legibility, jitter, or noise problems, missing data, and overall appearance. At each distance, line width and brightness measurements were made. Intensity was measured at the center of thp display. Horizontal line width measurements were taken at the center and at the north and south ends of the display. Vertical line width measurements were taken at the center and at the east and west ends of the display. The on-line test pattern was displayed on the PVD and used when the measurements were taken.

The equipment used to take line width and brightness measurements was shown in figure 1. The equipment is listed in table 1. The line width and brightness measurements that were taken with various lengths of cable connections are listed in table 2.

At distances of 20, 50, and 70 feet, any differences that may have existed were visibly indistinguishable compared to the unswitched mode. All of the data were legible and clear. There was no evidence of noise or jitter throughout the display.

At a distance of 100 feet, the overall appearance of the display was still similar. The characters were still clear and legible although there was some problem with the unblanking signal, causing a minute amount of character-stroke blanking. Also, some of the vector intersections did not meet exactly. While no attempt was made, these problems could probably be corrected by realigning the driver PVD.

At the 100-foot distance, there was a slight amount of jitter occasionally at several positions on the display.

When the switch PVD was cabled to 70 and 100 feet from the driver display, the overall size of the displayed data was reduced. This was easily corrected by adjusting the 200-ohm X and Y adjustment trimpots on the A5 PCB of the switch PVD.

When the switch PVD was switched between the NAS and the external input from the simulated 9020R, the R-control interface was switched between two different output connectors of the system RKM. The R-controls functioned in either position. When the PVD was switched, there was no impact on the NAS other than the single printouts listed in figure A-2.

CONCLUSIONS

The switch Plan View Display (PVD) operated very well up to 50 feet. At 70 feet, the display presentation was still very good. At 100 feet, the only major problem was an intermittent small amount of jitter a few places on the PVD screen.

The brightness and line widths of the display presentation were not affected significantly when driving the switch PVD at distances up to 100 feet.

The PVD's could be modified and switched back and forth between the present National Airspace System (NAS) and a future 9020 Replacement (9020R) System with no appreciable impact on the present NAS operation during the transition period.

APPENDIX A

PVD MODIFICATION DOCUMENTATION

The Plan View Display (PVD) was modified to display either the normal data received from the present National Airspace System (NAS) or external analog X and Y deflection signals, video unblanking signals, and category bits from a future 9020 Replacement (9020R) System. Data are selected by means of a switch on the front panel of the PVD. The R-control interface is also switched.

A block diagram of the PVD modifications is shown in figure A-l. A simplified drawing of the radar keyboard multiplexor (RKM) switch is shown in figure A-2.

A spare switch located on the System Status Control Panel of the PVD was wired in and used to control relays mounted on the video intensity control printed circuit board (PCB) (A2), the signal pattern correction PCB (A2), and a circuit board located in the RKM switch box. These relays are used to switch the PVD back and forth between the two modes of operation.

Flush-mounted inverted integrated circuit (IC) sockets were used on the A2 and A5 PCB's. These sockets were glued to the component sides of the PCB's. Using this type of socket eliminated the need to drill holes for the socket pins. Small pieces of fiberboard were glued between the sockets and the PCB's. These were used as insulators.

The A2 PCB modification required four !4-pin IC sockets and four 16-pin IC sockets. The 16-pin IC sockets were three SN75115N and one SN75122N line receivers. The 14-pin IC sockets were three Sigm& 195 TE-2CIE-56 relay IC sockets and one 14-pin header containing resistors. A BNC connector and a signal connector were also mounted on the A2 card using brackets and standoffs.

The Al PCB modification required one 14-pin IC socket and one 16-pin IC socket for a sigma 195-TE-2CIE-56 relay and a header containing resistors. Two 200-ohm trimpots and two BNC connectors on a bracket were also mounted on the Al PCB.

Photographs of the component sides of the modified A2 and A5 PCB's are shown in figures A-3 and A-4. Figures A-5 and A-6 show the schematic and layout of the video intensity control PCB before and after being modified. Figures A-7 and A-8 show the schematic and layout of the signal pattern correction PCB before and after being modified. By examining the drawings, it can be determined which connections should be opened and which connections should be made in order to complete the card mod ifications.

Figure A-9 shows a photograph of the RKM switch box. Figure A-10 shows the layout and wiring of the relay card which is mounted inside the box on standoffs. The relays are Sigma type 195 TE-2CIE-56. The "P" connector shown on sheet 3 of figure A-10 is an Amphenol Type 17-20250-1 (390). The "C" and "N" connectors are duplicates of the R-control connector on the PVD.

Figure A-l1 shows the lower basket of the modified PVD. The three coaxial cables and the signal cable are brought out directly from the PCB's. In a field version, BNC connectors and a signal connector would be mounted on the PVD chassis. Short cables from these connectors to the PCB connectors would be used to bring the signals to the external PVD connectors.
