PRODUCT SHOWCASE Portable DSO & test instrument The Palmscope 320, designed and manufactured by Escort Instruments, is unlike other portable, integrated test instrument packages. The four auto-ranging instruments integrated into Escort's Palmscope 320 are: a 2-channel 20MHz digital storage scope; a 3-3/4 digit true-RMS digital multimeter (with AC/DC amps); a 7-digit, 20MHz frequency/period counter and an 8-channel, 20MHz logic analyser. The unit has specifications normally only found on dedicated bench top instruments. The unit has specifications normally only found on dedicated bench top instruments. Some of these specifications include: 2K (1920 point) deep DSO memory; accuracy of 10ppm on the frequency counter and an 8 channel logic analyser with both timing and state signal displays. The Palmscope 320 is supplied complete with oscilloscope and multimeter probes, protective rub- VF-100 true-RMS mains monitor For country people who generate their own electricity, whether by wind, solar or water power, Callignee Electronics has released the VF-100 mains monitor. The device is intended to prevent damage to sensitive equipment by verifying that generators are running at the correct speed and that battery inverters are adjusted correctly. The unit measured "true RMS voltage" and cycles per second" of the mains supply and displays the results on a LED bar-graph display. The VF-100 is also widely used by electricians and generator mechanics who service and install alternative power systems. The price is $170 plus tax where applicable.

New A/D converter board from Procon Procon Technology has released an externally mounted analog input board that extends its range of input/ output boards manufactured in Australia. The ADC-808 provides eight analog inputs with 8-bit resolution and is available with 0 to 10V or 0 to 20mA input ranges. Other configurations are available on request. An industrial version, the ADC-808/I, is also available with 500 volt isolation between each analog input, detachable screw terminals for easy installation and extended supply voltage range. The board measures 240mm by 100mm and is capable of being DIN rail mounted. A single IBM-PC interface card (PB-BD-IO) is available that plugs into an 8-bit card slot and connects to 15 ADC-808 boards. This offers up to 120 analog inputs. Alternatively, the boards may be connected to any standard bi-directional parallel printer port (available on most notebook and industrial computers) to provide up to 56 analog inputs. Different configurations of analog and digital input/ output cards are possible with this interface. Typical applications include process April 1995  81 monitoring and control, energy management, home automation, security systems and industrial control. Other boards are available in the range, including opto-isolated digital input and relay output boards. All are available with the industrial option. All boards come with example IBMPC software for programming from most languages and are compatible with the Programmable Logic Control (PLC) language, developed by Procon Technology.

CCTV observation systems The OLS-100 with 10" screen and OLS-120 with 12" screen, are complete packaged plug-in ready to use observation systems. They are Intel microprocessor controlled and feature automatic, period adjustable sequential camera switching, 2 way monitor/ camera audio communication, sensor inputs & VCR output. Each package includes a combination monitor/intercom and automatic 4-channel switcher, a 400-line 0.2 Lux CCD camera with 12mm lens, a camera stand and a 20 metre camera cable. To use, simply mount the camera, connect the monitor and switch on. Camera cable length may be extended using a plug-in coupler. The single lightweight multi-core 5mm diameter camera cable is installed with the aid of adhesive cable holders. Each unit supports up to four cam- eras and four sensors. Three styles of intercom camera units are available, conventional C mount, eyeball and flat, with wide angle lenses. In addition, tiny pinhole modules, which can see through a 2mm hole, are available for concealed applications. Sensor inputs on each camera allow monitoring of camera locations using PIR or other devices. If a sensor is tripped, an alarm sounds and the image from the camera in the violated area is automatically displayed on screen. PowerPCB Cad package PADS Software Inc has announced PowerPCB for PC board design, intended for users who work with UNIX or Windows. This has a number of advanced features including a shape-based PCB editor which allows freedom from grid restraint during placement, routing and editing, a dynamic route editor which has semi-automatic 45* routing to avoid obstacles or move them out of the way, plus conditional rules and design rules hierarchy. At the same time as the release, special offers are being made to users of protel and P-CAD to enable them to buy PADS software.

High capacity tape backup system Hewlett-Packard has announced the release of its Jumbo 1400 tape backup system which provides 680 megabytes of storage on a single mini-cartridge or 1.36Gb using data compresion. The Jumbo 1400 is an internal drive that installs in normal 3.5-inch or 5.25-inch half-height bay. It can inerface to a PC's floppy disc controller but the system also includes a separate high speed controller that takes advantage of the drive's maximum transfer rate of 2Mb/s and provides backup rates of up to 15Mb/ minute. The system includes one pre-formatted mini cartridge and backup programs for Windows and DOS. Australian pricing is expected to be under $700.

New Yokogawa digital scope Wi t h u n i q u e 1 0 - b i t , 100Ms/s A/D converters in each channel and a 100K word length, the new DL4100 digital oscilloscope from Yokogawa gives four times better vertical resolution and 100 times better horizontal resolution than scopes with conventional 8-bit A/D converters and 1K word memories. This allows highly accurate measurements to be made on the most complicated waveforms. The DL4100, 4 channel 150MHz digital storage oscilloscope is designed specifically for use where accurate and reliable measurements are to be made on complicated waveforms, such as TV signals, AM signals and noise signals. Greater measurement accuracy is also achieved in multi-channel measurements by virtue of the DL4100's split display mode. This allows a full scale to be applied to each signal in a separate screen area, rather than the amplitude of the trace having to be reduced to view each input signal, and thus incurring an increase in errors. Also ensuring high accuracy measurements at all times, the DL4100 automatic self-calibration feature initiates every 30 seconds or when settings such as time/div are changed. When the DL4100 is to be used for advanced analysis or as part of a larger measurement system, or if hard copy plots are to be obtained, connection can be made via a built-in GPIB interface.
