Of particular note are the 40 or so pages of components specifically for TV/monitor and VCR servicing. All items are well indexed and illustrated, either by line drawing or photograph, with pricing details included. Rockby Electronics, based in the Melbourne suburb of Huntingdale, claim that most items in the catalog are ex stock and will express post, overnight air freight or local courier (Melbourne only) with just a $10 minimum order. They also have a web site which often has products not featured in the catalog (www. rockby.com.au).

The VIP96 PLUS is a panel‑ mou nting instrument providing visual readout as well as digital output via a multi‑drop communication. The instruments measure the value for line voltage and current power factor, analysis for voltage and current to the 24th order including percentage values as well as the individual displacement phase angles and total harmonic distortion (THD) expressed as a percentage. The VIP96 PLUS measures power (kW, kVAr) and energy with programmable integration times ranging from 1‑60 minutes. The instrument is fully programmable for any CT or PT combination. Networking software is provided by the VIPLINK/VIPLOAD and VIPVIEW packages, permitting up to 247 instruments to be linked to a central PC.

It comes with a tool which assists in removal. A 30ml bottle retails for $9.95 (Cat. N-1204). It is available from all Dick Smith Electronics stores and dealers. For fur- ther information, contact Dick Smith Electronics, Lane Cove & Waterloo Rds, North Ryde NSW 2113. Tel 9937 3200; Fax 9888 1507. CD pickup meter for jitter measurement Leader Instruments have released a CD Pickup meter designed for real time measurement of jitter in EFM signal output from a CD player. Stable measurements can be performed even when track jumping occurs or when measuring stained or scratched discs. The instrument automatically tracks an input signal over a range from 30mV to 3V. The measurement is compared with a preset value and displayed in GO/ NO GO format. A DC voltage proportional to the meter indication can also be obtained. For further information, contact Stantron Australia Pty Ltd, Suite 1, Unit 27/7 Anella Avenue, Castle Hill, NSW 2154. Phone (02) 9894 2377; fax (02) 9894 2386. Wideband receiver for EMC testing The new AFJ EMI modular receivers cover the frequency range from 9kHz to 1GHz and are suitable for full EMC compliance and operate in spectrum analyser mode. They are equipped with quasi‑peak detectors and can have up to 10 fixed and tuned preselector filters, providing more than 40dB attenuation for intermediate frequency, image frequency and intermodulation effects. Optional features include short and long click counting, as well as continuous interference observation via tuning to CISPR‑required frequencies. The ER55 receivers are PC‑based and are controlled by Windows software. This enables the operator to set up parameters as specified by CISPR 16 or according to individual requirements. The program allows the setting of frequency range, frequency step, selection of detectors (peak, quasi‑peak and average) and antenna correction factors. Customised software for communication with controllers of slide‑bars, turntables and antenna masts is also available. A wide range of accessories includes LISNs, bi‑tonic, log‑periodic and broadband antennas, loop antennas, near‑ field probes, passive probes and absorbing clamps.
