How versatile can a portable oscillograph be?

Just look what CEC's compatible 5-124 can do! Analog Recording • Analog Digital Recording • High-Speed Printing • PDM/PCM Readout • Decommutator/Printing • Com­puter Readout • Digital Time Code Readout

In the lightweight class, CEC's low-cost 5-124 Portable Oscillograph (shown above with DATAFLASH Takeup Accessory) has long been the accepted standard. For this is the "compact" that has brought precision measurement to industry at a price everyone can afford.

D a t a D i g i t ™ C h a r a c t e r Generator adds a new dimension to l ight beam osci l lography

This new C E C accessory offers a flexibility and accuracy never before available with an oscillograph of such modest cost and size.

Until the advent of the DataDigit Char­acter Generator, the basic limitation of all direct-write recorders had been the inability to divorce time from the trans­port speed of paper or film. But now, with up to nine columns of digital recording capability, paper speed be­comes virtually an independent variable with reference to time. A permanent record of analog/digital data can be obtained at accuracies approaching 0 .01%, and time correlated to 300 microseconds.

Furthermore, DataDigit provides the required waveforms for printing deci­mal data on a light beam recording oscillograph. Up to 1280 lines-per-second can be printed on the 5-124, or

approximately 700,000 characters-per-minute. A typical hybrid 5-124, with six analog signals being recorded, could print up to six columns of decimal infor­mation — simultaneously in exact time correlation with the analog data.

DataDigit follows CEC's new modular concept allowing for expansion from one to two columns per set to a full case of six module units. With proper selec­tion of galvanometers, up to four 5-124s can be paralleled for purposes of dupli­cate digital data, such as range time.

Standard advantages of the 5-124 © Records dynamic o- static data from d-c to 13,000 cps with rugged, easy-to-use CEC 7-300 Galvanometers — thereby achieving superior performance with high reliability. [•] Achieves writing speeds up to 50,000 ips on 7-inch-wide records. [•] Up to 18 analog channels or 9 columns of digital data can be recorded and read out with no chemical processing required. If] A complete new line of record-drive sys­tems—sixteen options from 0.25 ipm to 128 ips. Among them, a millimeter drive which covers the range of medical recording. [i] The standard bench mount version is fully adaptable to benchmount with takeup, individual rackmount, rack mount takeup, rack mount internal takeup and rackmount with DataFlash and internal takeup.

Optional Accessories The 5-061-2 DATAFLASH Takeup Accessory, adaptable to any existing 5-124, permits one-second readout of rec­ords at speeds up to 4 ips at frequencies from d-c to 13,000 cps. Top speed becomes 128 ips with only 1 minute required to readout. The Rapid Latensif icat ion Wri t ing Deck, which fits on the front of the graph, is designed to enable the user to make data notations prior to recording for checking calibration levels, and to make notes on the recording paper at slow speeds.

The New 1-165 D-C High-Gain Differ­ential Amplifier, compatible with all CEC Series 7-300 Recording Galvanometers, has the output capability (± 10 v at 100 ma) and a plug-in damping assembly to prop­erly damp and drive all other currently available recording galvanometers. Provid­ing a frequency response of ± 3 % to 15 kc, the 1-165 can be intermixed with the 1-163 Medium-Gain Amplifier and 3-140 Power Supply Modules in a common mounting case, and may be either a fixed rackmount or slide rackmount/benchmount.

The Internal Takeup Rackmount is a low-cost, simplified version of the DATAFLASH Takeup Accessory —minus the heated platen and latensifier lamp. However, the heated platen may be readily added if and when required. Ambient Light Fi l ters , for use with either the bench mount takeup or rack mount takeup versions, permit darkroom processing to achieve recordings of archival quality.
