PRODUCT SHOWCASE 200MHz TekScope from Tektronix Tektronix has announced the THS730A, the top of the range oscilloscope/ DMM in its TekScope family of products. The THS730A model operates at 200MHz, with 1Gs/s sampling rate and features the Tektronix exclusive Isolated Channel Architecture for user and circuit safety as well as wide bandwidth. Developed for electronics design and test engineers, as well as for field troubleshooting, the THS730A offers high speed dual channel/dual digitiser measurement and triggering capabili­ ties for quick timing error detection. The THS730A utilises the TekScope graphical user interface (GUI). Other features of this oscilloscope include comprehensive and advance triggering, glitch capture, dB and dBm measurements. Other members of the THS700 oscilloscope family include the THS­ STEPDOWN TRANSFORMERS 60VA to 3KVA encased toroids Harbuch Electronics Pty Ltd 9/40 Leighton Pl.

Thingamebobs & Douvres MicroZed Computers has released two kits for making pro­totypes. Intended for use with BASIC Stamp control computers, these kits are designed to minimise soldering, speed proto­typing time and allow reuse of prototypes. Stamp boards, like most other small computers, come with a 0.1-inch matrix of plated through holes. Soldering and unsolder­ ing more than a few times deteriorates the prototype area of the board. MicroZed’s Thingamebob wiring kit is a low-cost, ready-made solution to match the Stamp’s header strip connections. The basic wiring kit has 20 x 150mm coloured wires, two each of the 10 colours used for resistor values. Each wire is terminated with a single pin plastic housed socket for slipping onto a header pin. A feature of the Thinga­mebob kit is that a selection of multiple pin housings are supplied, so that a multi-pin socket can be made. A 40-pin single row header strip is supplied, so that the idea may be interfaced to “breadboard” style proto­ typing kits, used to connect to other circuits, or to “daisy chain” Thinga­ me­bob wires, where multiple power, common or communication lines are needed. Five spare header connecting sockets are supplied, to use on your own wires. Recommended maximum current capacity for Thinga­ mebob wires is 1000mA. Warning: Thingamebobs are not suit­ able for use on 240V mains wiring. Douvres for Stamps is a small kit of simple circuits, already wired and ready for attachment to the header pins. Each Douvre kit contains seven circuits: a piezo sounder, a thermistor circuit, a potentiometer circuit, a pushbutton circuit and three LED circuits (red, green and orange). Purchasing a Douvres kit allows a novice user to learn and use Stamp commands within an hour of opening a kit. Professional users, on the other hand, will find that they eliminate the tedium of search­ ing for parts and making up mundane circuits. Packed in a small reusable plastic box, Thinga­me­bobs are priced at $24.00 and Douvres $34.00, including sales tax. Quant­ity and tax exempt prices are available.

Please feel free to visit the advertiser’s website: www.emona.com.au/ Component counting scales Manual component counting for batching or stock-take is one of the big time-wasters in the electronics industry. Fortunately, most electronic components are very nearly identical in weight, allowing them to be easily counted by weight. The PS1015 is a high resolution, portable counting scale. A rechargeable battery is installed to allow a full day’s work, before overnight recharging with the power pack supplied. An internal resolution of 40mg ensures accurate counting of small components and pins used in many products. The maximum capacity of 1.5kg allows counting of some of the larger components, in­cluding electrolytic capacitors, or the large quantities found in some bulk packs. The three panel display shows total weight, unit weight and current count simultaneously. Back lighting provides for easy viewing, even in the dim back corners of some stores. When not in use, the display can be folded down for storage and transport. The measuring tray is 230 x 280mm, large enough to accom­modate a wide range of containers. The one-touch Tare button returns the display to zero for counting after a new container is placed on the platform.

The package presents emulation data by their symbolic names, allows assembling and automatic back notation of edited error-report files, and generates extensive assembly warnings to prevent those pitfalls. The tool kit runs on an IBM compatible PC. System require­ments are 386+, DOS, mouse, printer port and a small amount of extended memory under himem.sys or equivalent. The user-screen presents all information required for emulation and simulation and provides immediate access to the accompanying PICASM assembler and user-supplied editor. A multi-function oscillator is included. The user can select the clock source to be a user-supplied crystal or oscilla­tor, a special clock signal located on the target board, or the stable (5kHz- 20MHz) VFO on the ICE card. The VFO frequency is selected in four Programmable video generator Leader Instruments has released a new programmable video generator, the LT 1610. The unit can drive a wide range of displays from LCD to CRT and can be easily controlled from an external personal computer through an RS232C interface. The LT 1610 is provides full digital 8-bit 120MHz output of dot clock and analog RGB 150MHz output of dot clock. It enables easy programming of the following functions under the Windows environment: horizontal timing, vertical timing, output conditions and output patdecades and can be fine adjusted, with the ICEPIC screen acting as an accurate digital frequency meter. An on-board switching power supply generates all the re­ quired voltages from an external 12-24VDC or AC power source. The ICE card communicates bi-directionally with a printer port on the user’s PC.
