WJ-9195 RASP System
The original WJ-9195 RASP unit was an advanced Digitally Refreshed Display (DRD) unit that controlled a specially modified WJ-8617B to generate a display. It consisted of:
WJ-9195/DRD-1 - Digitally Refreshed Display (middle unit in photo above) - functions as scan controller and processor for a specially adapted WJ-8617B receiver.
WJ-9195/CRT (top unit in photo above) - standard NTSC display monitor in slick WJ cabinet.
WJ-8617B-2 or WJ-8618B-15 (shown - bottom of rack) - specially modified WJ-861xB series receivers
for rapid spectrum scanning. The WJ-9195 will not function with any other WJ
The WJ-8617B-2 or WJ-8618B-15 have specially modified fast settling
synthesizers to allow the fast scanning mode and special control codes in the
GPIB interface. See the WJ-8617 and the WJ-8618 version guides for more details on the -2 and -15 variants of these two receivers.
