The Tektronix WP1000AF Signal Processing System is a bundle of a DPO, two 7A16A vertical plugins and two 7B71 horizontal plugins. All components have additional modifications (Mod 515C or -D), which allow an external computer to control some of the front panel settings. The National Stock Number (NSN) for this bundle is 6625-01-034-4833.

Mainframe
The 7704A Mod 515C adds the ability to remotely operate the vertical, horizontal and triggering modes of the mainframe. Additional connectors on the rear are directly connected to the plugin-compartments to allow remote operations for the plugins.

7A16A Mod 515D Plugin
The 7A16A Mod 515D adds the ability to remotely operate the Bandwith, Polarity and Position functions of the plugin.

| B horizontal plugin | GND | GND | GND | GND | Open (n.C.) |
Field of Application
Some details of the modification indicate that the WP1000AF system was developed either specifically for or in close consultation with Honeywell. Honeywell did some additional, but minor modifications to the system. The feet were modified so that the device could be fixed in place. They also added a cable tie holder and a tag to the back of the unit. The result got the Honeywell part-number 10066273-101 and the NSN number 6625-01-060-4390. The pictures on this page show such a device. Honeywell most likely used one of their own type of computer systems to control the DPO.
The contractors name and the contract number (see picture below) indicate that this specific instrument was involved in the development of the F15 aircraft project. And this external page: Michael J. Gooding, H. W. Sweatt Award reveals that a WP1000AF system was used in the Test Environment (TITE) for the F15 Tactical Electronic Warfare System (TEWS).
