Digital ohmeters take on inductive loads
AVO International has extended the capabilities of its popular Ducter DLRO10 and DLRO10X digital low-resistance ohmeters to include accurate resistance measurement for inductive loads.
LCR meter sheds light on mystery passives
With the latest LCR meter from AVO International, the modern trend for electronic components to carry no markings to identify their function is no longer a problem for service and test engineers.
The compact and lightweight, yet rugged, BERT 20E1, which offers the industry's longest internal battery life of seven hours of continuous operation, incorporates an independent transmitter, together with primary and reference receivers.
This combination enables it to perform either in-service or out-of-service evaluations by locating complete failures in a transmission line or piece of equipment, verifying network performance, isolating faulty data terminal equipment (DTE) or data communication equipment (DCE), and determining faulty data channels.
The BERT 20E1 can be used at the DSX-1 cross-connect, or can be a substitute for transmission equipment in real-world testing.
Users can choose between ten operating modes, among which are automatic, fractional E1, tone insert, and bridge-tap testing.
To provide greater versatility and convenience, the BERT 20E1 performs bit error-rate testing (BERT) on one of 17 standard stress patterns, plus two user-definable patterns; measurement of carrier and channel levels and frequencies; and detection of timing problems, including clock slip.
All functions are selected using clearly identified keys on the instrument front face, and full details of the functions chosen are confirmed by a large liquid crystal display.
The same display is also used to show test results, with multiple results readily accessed via a scroll facility.
An integral printer port also allows results to be printed using almost any standard printer with a serial interface.
To guard against obsolescence, the BERT 20E1 from Megger will accept software upgrades or additional stress patterns.
These can be loaded into the instrument in the field, eliminating the inconvenience of having to return it to the manufacturer's service department for updating. Request a free brochure from Megger ...
