single hoard computer ACC 2186: Typical applications include: - DEC J-Ii one chip processor with PDP 11/70 performance - console interface at up to 38.4 KBauds - on-line data reduction systems ~ fast 128 Kbytes dual-port memory - second level trigger processors - true sultiprocessor structure, - pulse height analysis systems mini-backplane BP 2134: - monitoring systems in difficult environment - 4 dual slot 022 bus format - portable high speed data loggers - optional ETHERNET interface (DEONA) - laboratory automation systems - optional 8PIB (IEE-4BB) interface

- optional memory extensions and peripheral interfaces, * PDP,J115RSX are registered trademarks of DEC disk subsystem DSK 2135: - 16 Hbytes high speed Winchester disk - optional floppy disc or streamer for back-ups.

This system outperforms top of range micros and runs standard DEC software.The normal configuration runs RSX-iifl with BASIC,CATV,FORTRAN and PASCAL, iloreover the software can be developped at the VAX host computer level and down-line loaded for execution in the local workstation.

Accelerators, fusion experiments, se­ miconductor production, and metal­ lurgy are examples of the uses these vacuum pumps can be put to. In one case, efficiency is the decisive factor, and in other cases the technical de­ pendability and ease of handling. The Turbo 1500 is an ideal combina­ tion of all these factors.

The most economical turbo pump A cost/benefit ratio was able to be with high volume flow rate achieved for the Turbo 1500 which makes this pump truly competitive.

PEARSON Wide Band, Precision

Current Monitor With a Pearson current monitor and an oscilloscope you can make precise amplitude and waveshape measurement of ac and pulse currents from milliamperes to kiloamperes. Currents can be measured in any conductor or beam of charged particles, including those at very high voltage levels. A typical model gives an amplitude accuracy of +1 %, - 0%, 20 nanosecond rise time, droop of 0.5% per millisecond, and a 3 db bandwidth of 1 Hz to 35 MHz. Other models feature 2 nanosecond rise time, or a droop as low as 1 % per second. Contact us and we will send you engineering data.
