Fullymodular in 16-channel increments, the 64300.provides 64 channels in a full-up configuration,which includes 16 300-MHz (3.3-ns resolution)asynchronous channels for timing analysis and48 25/50-MHz synchronous/ asynchronouschannels for timing/state analysis.The company states that in time measure-

ments, the 64300 is the only logic analyzeravailable with a genuine dual-time base; it cancapture and correlate independently clockedsignals, and overlay a 300-MHz acquisitioncapability on any channel. A 300-MHz capa-bility is designed to give the user a truer pic-ture of the operation of the system under testby permitting a 3.3-ns resolution with glitchdetection capabilities.The analyzer offers microprocessor-specif-

ic interfaces and disassemblers for all populareight- and 16-bit processors, and these incor-porate features such as 12-level, two-dimen-sional triggering that help to isolate problemsand unravel machine code. Performance fea-tures included as standard with the 64300 aremultilevel triggering; Datapak integrated,transportable mass memory; multiple inter-nal/external clocking capabilities; search andcompare; up-trace module with full disassem-bly; RS-232-C/IEEE 488 interfacing; andsoftware performance analysis features, in-cluding time stamp, area trace, and histo-gram.

Prices of the 64300 vary from $7930 for a16-channel implementation to $14,930 for the64-channel implementation for 16-bit micro-processor and microprocessor-based-systemanalyses.

Real-time spectrum analyzer plugs into IBM PCs

The Ariel Corporation's RTA 331 is al/3-octave real-time audio frequency spectrum'analyzer that plugs into a single expansion slotinside the IBM PC. The analyzer divides theaudio spectrum into 31 "/3-octave bands from20 kHz to 20 kHz and interactively displaysthe relative amplitude of each frequencyband. The unit can also convert an incomingaudio signal to eight-bit samples and store it inthe PC's 512K-byte main memory in which 20seconds of audio can be stored. Any block ofmemory can be similarly read out using theanalyzer's eight-bit DAC.

Assembly language subroutines handle allhigh-speed operations. All subroutines are ac-cessed from Basic, so users can create new andspecialized applications such as digital signalprocessing and speech synthesis or recogni-tion. The RTA 331 features on-board pinknoise generator, digitally controlled gain, 1/4dB resolution, and ANSI A, B, or user-defined weighting, averaging, and peak-holdfunctions.

Video image processor stores image data digitally

A video image processor designed to con-vert radar or sonar video signals to TV rasterscan for display on a standard televisionmonitor has been introduced by Hughes Air-craft Company's industrial products division.According to the company, operators nolonger have to rely on long-persistence phos-phors in their CRT monitors for retention oftarget images until refreshed by the next sweepof the antenna. With the Model 666, imagedata is stored digitally and can be displayedcontinuously.

The image can be displayed on remote orlocal monitors, or it can be recorded onvideotape. The radar/sonar image can beviewed in normal ambient lighting, elimi-nating the need for a darkened room. The pro-cessed image is electronically smoothed toprovide an appearance similar to that of aconventional television display. When ac-tivated, selectable image fade algorithms

emulate the phosphor fade characteristic ofan analog radar display.

Stored information can be displayed simul-taneously with dynamically updated informa-tion. A vertical gray calibration scale appearsat the side of the radar/sonar display, andalphanumeric legends and messages can beoverlayed on the image or written in desig-nated locations outside the displayed imagearea.Memory consists of MOS dynamic RAMs

organized 512 x 512 x 4 bits, and imageresolution is 512 pixels per line x 480 lines.The unit is microprocessor controlled with upto 8K bytes of program memory and 768 bytesof RAM to execute processing commands.Analog sweeps can be entered with sweepspeeds up to 51 microseconds full scale and apulse repetition frequency up to 1000 Hz.The single-unit domestic base price is

$25,000.

Portable logic analyzerincorporates CP/M micro

The portable, 27-pound Omni 11 logicanalyzer from Omnilogic, Inc., integrates atiming/state logic analyzer with a full-func-tion CP/M microcomputer while incorporat-ing a software-intensive design approach.Used as an interface between the engineer

and complex digital problems, the Omni II

can collect 1000 data samples on each of 16channels or, optionally, up to 48 channels of330 samples each. Four channels of glitchdetection are provided with a minimum de-tectable pulse of 10 ns. The system utilizes in-ternal or external clocks as fast as 20 MHz,either of which can be qualified. Triggeringmodes include the basic AND/OR/NOT ondata or glitch, with the trigger point position-ed within the 1000-word sample memory. Ad-ditional triggering modes are absence ofrepetitive event, repeat until correlated withreference memory, and delay by event or time.External trigger and trigger qualifier are alsoprovided. Two rear-panel connectors supplyclock and trigger outputs.Upon power-up, the Ommni II invokes an

automatic self-check of its internal circuitry,and a "setup page" automatically appears topermit configuration of the machine for datacollection. After data collection, the analyzerprovides the timing analysis for hardwaretroubleshooting and software analysis. Theintegral CP/M computer utilizes a Z80 CPUand 64K of RAM. Mass storage is provided bytwo 5¼/4-inch, double-density disk drives. Thebuilt-in, nine-inch monitor displays 24 rows

by 80 columns in P31 green phosphor. A de-tachable ASCII keyboard, with its cursor con-trol keys and numeric pad, provides control of

Another feature of the Omni II is its signa-ture analysis capability. It can derive the hex-adecimal signature of 14 independent testpoints simultaneously. These results can thenbe compared automatically with a set of

"known good" signatures previously savedon disk.

All digital testing parameters, data, andtime and date can be stored on disk, withCP/M compatibility, for additional off-lineanalysis. With the connection of a printer, theOmni II can provide hard copy of displays.The Omni 11 is priced at $3950.

Interface connects computers or WPs to telex lines

A series of telecommunication devices thatpermit computers, word procesors, orprinters to be interconnected with domesticand international telex systems without bulkyand expensive telex hardware has been in-troduced by Teleface Corporation. The Telex-plug is designed to adapt computer-relatedequipment as the transmission media forentering telex, TWX, or DDD networks, thusbypassing conventional telex machines. Onlyone party in an exchange between companiesor individuals needs the new interface in placeto access the various telex systems and con-duct "conversation."The interface operates on a microcomputer

chip that permits the design of a low-costgateway to various communications systems.The chip gives the interface the capability tohandle code and speed conversions up to 9600baud. Telexplug can be interposed directlybetween a computer or word processor and itsprinter or other output peripheral, permittingconnection through use of supplied cable toequipment with a single port. It can also beconnected to a separate communications port,allowing the equipment interfaced to engagein unrestricted communication with the newdevice. In this arrangement, Telexplug acts as

a modem to open two-way access betweencomputer elements and the telex network.A flexible memory enables the interface to

store incoming messages if connected com-puters or printers are busy; once the connec-ting equipment is free, the telex messagedistribution is activated. Users can choosefrom block or conversational telex modes foroutgoing messages. Once outgoing messageshave been prepared and edited on a user'scomputer, the Telexplug is activated, eitherdirectly or through a printer and sends themessage by itself-dialing, establishing con-nection, giving and accepting answer-backs(an identification signal of up to 20 char-acters), and transmitting the message.

Other features of the device include multi-linking to a telex line, direct and exclusive ac-cess for confidentiality, unattended opera-tion, message repetition self-diagnosis and theability to send different types of printed mat-ter-via ASCII serial asynchronous formatup to 8000 characters, and to store about threeincoming and outgoing messages.The cost for each unit of the seven Telex-

plug models is $1270.
