PRODUCT SHOWCASE Exceptional new Agilent scopes from HP Agilent Technologies Australia Pty Ltd, a subsidiary of Hewlett-Packard, has introduced a series of five oscilloscopes which combines the channel count, memory depth, display definition and triggering that design engineers need to debug mixed analog and digital designs. Users can now easily see more signal detail when debugging and verifying mixed analog and digital designs. The Agilent 54600 series now offers multiple-channel configurations: 2- and 4-scope channels or the mixed signal oscilloscope (MSO) with 2+16 channels (two analog channels plus 16 integrated digital channels); 2MB of MegaZoom deep memory that respond instantly to control inputs; a high‑definition display system and powerful triggering. These four attributes differentiate the Agilent 54600 series oscilloscopes from other 100MHz scopes and address the challenges of the digital designer. The 2+16 MSO models (60MHz 54621D and 100MHz 54622D) combine the detailed signal analysis of a ’scope with the multi‑channel timing measurements of a logic analyser. Users can view two analog and up to 16 digital signals simultaneously, to debug microcontroller problems that would stymie a conventional scope, such as triggering on a mix of digital bus states and analog signals. The 4‑channel, 100MHz scope (54624A) gives engineers the channel count and measurement power they need for designs that include heavy analog content. There are also budget 2-channel models (60MHz 54621A and 100MHz 54622A). All models have two megabytes of “MegaZoom” deep memory behind every channel which provide deep capture without the sluggish response and complex operation associated with some deep‑memory scopes. Because MegaZoom is not a special mode, it is always available to help find details buried in complex signals, to discover anomalies in the absence of good triggering events, and to correlate high‑speed digital control signals with slower analog signals. This, combined with the high‑ definition display system, provides unsurpassed horizontal screen resolution and the ability to map deep memory into 32 levels of gray scale at up to 25 million vectors per second. This combination enables users to view and understand complex signal details. It also greatly decreases the chance of missing a narrow, occasional transient, or overlooking a glitch or distorted edge that impacts circuit operation. Further information on these products may be found on the Web at www.agilent.com/find/MegaZoom For further information on pricing, availability and technical information, contact 1800 629 485 or email on info_tmo<at>agilent.com May 2000  53 Digital-ready TV signal analyser Matchmaster Communications has introduced the Italian-made RO.VE.R. TDA-4a, a lightweight, battery operated digital field strength meter for the TV installation and service industries. With a frequency range of 47MHz to 870MHz, the instrument covers both VHF and UHF TV as well as FM radio channels used in Australia. It can carry out the following measurements: video carrier level, digital package average power, audio carrier level, FM radio carrier level, audio/video carrier delta plus analog and digital TV carrier to noise ratios. All measurements are shown on a multi-mode LCD panel which gives a variety of readings. A switchable FM or AM universal audio demodulator is also tunable from 44MHz to 870MHz. Received au- Safer fume extractors dio can be heard through an inbuilt speaker. An inbuilt rechargeable NiCd battery pack gives up to 12 hours portable use. A 240V mains adaptor and 12V DC car cigarette lighter adapter are also included. These will power the unit as well as charge the battery. The meter is fitted with a male “F” style 75Ω RF input connector with male to female and F to IEC adaptors supplied. The instrument is housed in a heavy duty plastic carry case which also has provision for storing the test leads and power supply. For the TV antenna installer, the CATV cabler and related areas, a device such as this would save an enormous amount of time and trouble. Being able to read signal strengths directly over all the required channels would make antenna aiming a breeze and also the detection of faults much more simple. With a trade price of $1300, the RO.VE.R. TDA-4a is available through sole agent in Australia, Matchmaster Communications, 48-50 Belmore Rd, Punchbowl NSW 2196. Phone (02) 9153 6666, Fax (02) 9153 9099 . The Alsident System ESD 50 and ESD 100 series of fume exhaust arms from Pyrotek are the first to gain certification for use in electrostatic discharge sensitive and explosion sensitive applications. This certification is also good news for computer and other electronics manufacturers whose reject rates are lessened by any measure that lowers the risk of electrostatic discharge through sensitive components. It is equally important for laboratories or chemical, pharmaceutical and food industries facing the need to exhaust powders, combustible gases or dust/air mixtures or fumes which pose possible explosion hazards. Extracting solder fumes is another example. The systems can be mounted on a wall, worktable or ceiling and the three joints enable the operator to effortlessly position the mount anywhere within its 1350mm reach. Adhesive resins do not threaten the conductivity of the system. The entire pipe system displays a resistance of substantially less than 1MΩ. The ESD 50 extracts at 85 cubic metres per hour while the ESD 100 exhausts at 400 cubic metres per hour. Over 100 variations in seven models of fume extractors are available with details in a free 18-page booklet, available on request to Pyrotek, 147 Magowar Road, Girraween NSW 2145.

Telephone Technical Services imports new US range of phone test equipment One of the side-benefits to the deregulation of the Australian telephone industry is increased access to installation, service and maintenance work for approved personnel. However, the availability of suitable equipment has been something of a problem. A Brisbane company, Telephone Technical Services, recognised the need for a range of high quality telephone and line test equipment and so has recently started importing the US-made “Test-Um Inc” range. Of particular interest are the phone test sets (called “butt phones”) which offer a broad range of testing facilities. There 54  Silicon Chip are two in the range, the “Lil’ Buttie” LB100 and the “Lil’ Buttie Pro” LB200. The big difference between the two is an LCD panel on the Pro model which reveals even more information about the line under test – even caller ID information. Other equipment includes tone generators and tracers, tell-all testers for both phone and data lines and similar devices.

Usually a standard VCR is pressed into service but these have several shortcomings in this application. Jaycar Electronics have addressed this problem with the release of a video recorder specifically designed for the purpose. Its major advantage is a variety of recording modes including the ability to store 24 hours of video and audio on a single E-180 (three hour) VHS tape. Recording times can be programmed for certain periods on a daily or weekly time frame, they can be continuous or they can be time-lapse. They can also be triggered by devices normally used to trigger an alarm (eg, PIRs, light beams, door switches, etc) or by the alarm unit itself. When an alarm event is triggered, the recorder will sound a buzzer and record for a predetermined period. Alarm event information is also recorded and up to eight events can be displayed, by date and time, on an external monitor. At the end of the tape the recorder can be set to rewind and re-record the same tape or it can eject the tape and wait for a new tape to be inserted. A further possibility is the use of additional recorders in series where at tape end the first signals the second to start recording and so on. Various playback modes are available including standard, slow, fieldby-field, reverse direction and slow reverse direction. Rear panel connectors are provided for video, audio, alarm in (trigger), alarm reset, alarm out, one shot trigger, trigger out, tape end, series in and series out. The recorder operates on 240V AC With a recommended retail price of $995.00, the QV-3050 Time-Lapse VCR is available from Jaycar Electronics stores throughout Australia or via the Jaycar Mail Order service (Phone 02 9745 3222) or their website: www. jaycar.com.au Mini video cameras to suit Two miniature video cameras, one colour and one monochrome (b&w), which would mate perfectly with the above Time-lapse VCR are also available through Jaycar Stores. Both are pinhole models, meaning a hole only a couple of millimetres in diameter is needed to view through. Camera size is just 36mm square x 30mm including lens. Both feature audio and video outputs, the audio via an RCA connector and video via a BNC connector. Power (12V DC <at> 120mA b&w, 130mA colour) is via a standard 2.1mm DC jack. Video output is 1V pk-pk <at> 75Ω and the B&W model operates down to 0.1 Lux (that equates to a scene lit by dim moonlight!). These cameras also respond well to infrared (invisible) light. The colour camera requires 2 Lux. A tiny swivel mounting bracket is also supplied which would enable the camera to be permanently mounted and aimed. The B&W model has a 1/3-inch Sony CCD image sensor giving 400 line resolution while the colour camera features a 1/4-inch CCD sensor and 330 line resolution. The monochrome camera (QC3476) has a recommended retail price of $149.00 and the colour version (QC3486) sells for $229.00.
