PRODUCT SHOWCASE Low-cost inkjet plotters from HP Hewlett-Packard has introduced two large-format inkjet plotters, the DesignJet 250C colour model and the DesignJet 230 monochrome unit. The 250C plotter is HP’s first large-format colour device designed specifically for the low end of the computer-aided design (CAD) market, while the 230 plotter replaces the model 220. The 250C offers colour output in three different print modes. The plotter’s four ink cartridges, cyan, yellow, magenta and black (CYMK), let users create a full range of colours with 300 dots-per-inch (dpi) resolution. It takes only six minutes for the HP 250C to print a typical A1 size colour CAD drawing in normal mode. The 230 plotter also features three print modes. It uses the same black print cartridge as the model 250C and both models produce black output in 600-dpi resolution. A black-only A1 size plot takes only five minutes on either plotter in normal mode (600 dpi). Commonly available media, includ- ing plain paper, vellum, translucent and polyester film, may be used for black-only plot­ting. For colour plotting, HP’s special inkjet paper must be used; it is readily available through drafting-supply stores and outlets where plotters are sold. The plotters come with Centronics/ Bi-tronics and RS-232 serial ports and may be connected to a LAN through an HP JetDi­rect EX external connection. The plotters come with HP-developed drivers for AutoCAD Release 11, 12 Power supply for train controller For those who need a robust power supply for the train controller published in the September & October 1995 issues, this unit from CIL Distributors should fill the bill. Based on a 120VA toroidal power transformer, it has two 15V AC outputs, each with a capacity of 4A. The unit is double insulated and housed in a high impact plastic case with soft rubber feet. It is fitted with a 2-metre power cord and has and 13, and Microsoft Windows 3.1. The plotters can switch automatically between HP-GL, HP-GL/2 and HP RTL modes. The HP DesignJet 250C plotter is $5440 for A1 size and $7408 for A0. The DesignJet 230 model is $4341 for A1 size and $5903 for A0 size. All prices include sales tax.

At five Gigasamples/second on four channels simultaneously, with a 1GHz bandwidth and eight bits of vertical resolution, the TVS600 series sets new performance benchmarks in VXIbased waveform analysis for advanced research and characteri­sation – and is fully VXI plug and play compliant. The TVS621 and TVS641 analysers are C-size VXI cards with two or four input channels respectively. Both modules incorporate digital real-time signal acquisition, derived from the TDS600 benchtop DSO, and have 250MHz bandwidth, simultaneous 1GS/s sample rates and 15K record length. The instruments’ trigger system discriminates on both edge transitions and pulse width, and responds to triggers on any of the 10 available back­plane trigger lines. The TVS625 and TVS645 are C-size VXI cards and feature a 5GS/s sample rate, 1 GHz bandwidth and 15K record length. Employ­ ing a digital real-time signal acquisition engine similar to that of the TVS621 and TVS641, these VXI modules can capture signals on all channels simultaneously with 200ps/point time resolution.

The DL1540 weights just 5kg and has a footprint smaller than an A4 sheet. The DL1540 is a long record length, 150MHz, 4-channel digi­ tal oscilloscope with a maximum sample rate of 200MS/s. It has a high speed update rate irrespective of the number of channels in use. It also acts as a recorder capable of capturing very fast RF current immunity tester The investigation and assurance of electromagnetic compa­tibility of equipment under the effects of radiated HF-fields, as specified by standards such as IEC 8013, involves the use of highly complex test facilities that are mostly to be found only in specialised test laboratories. Such tests can prove to be expensive if items have to be tested many times. The palm sized, battery-operated NSG 420 RF Current Immuni­ty Tester can help to minimise such costs. By using a substitu­tion method, involving the injection of HF-energy into power feed and interconnecting cables, valuable information regarding the interference immunity of a test object can be obtained, allowing the appropriate countermeasures to be incorporated at an early stage in the development work. The simplicity of operation and low cost also makes the NSG 420 a valuable tool on the production line to check the consist­ency of the EMC measures incorporated in a product.

Its 196 pages include over 10,000 line items available from RIE, ranging from customised computer systems, computer accessories, electronic accessories and components, solar products and hard-to-find products. All 10,000 line items are available from RIE’s outlets in the Melbourne, Northcote, Oakleigh, Box Hill, Vermont, Adelaide and Sydney. The mail order number is 1-800 33 5757. In keeping with the current trend of shopping on the Internet, RIE also now has an e-mail address: rie<at>ozemail.com.au. surge signals. Pulses as small as 20ns can be recorded in real time on an optional built-in printer. In single shot applica­tions, up to 120K word length is available and since the signal is first stored in memory, a fast sampling speed can be used, enabling signals of tens of MHz to be printed out. For slower signals, the DL1540 shows a waveform on its 7-inch CRT similar to a recorder, with a Roll mode allowing information equivalent to two pages (20K word) to be kept. The DL1540 has a built in 3.5-inch floppy drive that is MS-DOS compatible. This allows waveform data, panel settings and display to be saved and later included in a word processor docu­ment. A History Memory function stores the last 100 displays, any one of which may be recalled and magnified quickly and easily with the instrument’s Zoom function.
