SR430 Multichannel Scaler/Averager

Trigger Timing Atrigger pulse starts the data acquisition cycle. The SR430offers a choice of bin widths ranging from 5 ns to 10.486 ms.Alternatively, an external bin clock can be provided to theSR430, allowing you to define your own bin size. The number of bins in each record is adjustable from 1k (1024) to 32k in 1k increments. Data acquisition in the SR430 is seamless The 7 " CRTscreen allows flexibility in displaying yourresults. Between 8 and 16k bins can be displayed on the screen at any time, and horizontal and vertical zooming and scrolling features are provided. An “Auto-scale” key quickly optimizes the screen for the current data with a single key-press. Afast, responsive, on-screen cursor lets you read the maximum, minimum or mean data value from a selected range of the graph.  there is no dead time between bins. Oncethe selected number of bins has been recorded, the SR430 either adds or subtracts the result of the current record from the accumulated bin totals. Accumulation Data Display The SR430 can be programmed to accumulate between oneand 64k records, or set to free run. Each record can be added or subtracted from the current accumulator totals. The instrument can be set to toggle between add and subtract every N records, or an external toggle input can select the polarity of the next record. Arear-panel inhibit input allows you to selectively prevent the accumulation of any given record. The screen display is updated continuously as records areaccumulated, providing a live, real-time display of the data. menus and softkeys. The remote command list is also providedon a help screen as an aid in programming the SR430. Built-In Disk Drive Hardcopy output is available from the SR430 in a variety offorms. Astandard Centronics printer port lets you dump thescreen to dot-matrix or LaserJet compatible printers at any time. Additionally, the SR430 can plot its display on any HP-GLcompatible plotter via the RS-232 or GPIB interface. Both RS-232 and GPIB interfaces are standard on the SR430.All instrument settings and functions can be read and set via the interfaces. Acomplete list of all characters received andtransmitted over the interfaces can be displayed on the CRTscreen The SR430's extensive capabilities don't stop with dataacquisition. Savitsky-Golay smoothing can be applied to anyportion of the data, with selectable smoothing intervals.Gaussians, exponentials or straight lines can be fit to arbitrary regions of the display, allowing you to quickly determine decay lifetimes. Basic statistical parameters can be calculated for data regions including total number of counts, mean number of counts, and variance. Basic arithmetic operations, including addition, subtraction, multiplication, division, logs and square roots, can be applied to the current data. The SR430 has a built-in 3.5 Hardcopy Output Complete Programmability  an invaluable aid when debugging your programs.Numerous modes are available for downloading the count data to your computer including ASCII transfer, binary transfer, and a fast binary dump mode which transfers datacontinuously over the GPIB interface as it is being acquired. " DOS-compatible disk drive tosimplify data transfer between the instrument and your computer. Both data files and settings files can be stored so you can save complete instrument setups for a variety of situations and recall them instantly. Data Analysis Menus and Softkeys The SR430 is based on a simple, menu-based user interface.Each menu groups related instrument functions and defines softkeys to control those functions. The instrument settings are changed by pressing the softkeys or by turning the front- panel knob. Complete context sensitive help is provided for all
