Popular benchtop-DMM line offers expanded capabilities
By Dan Strassberg -- EDN, 11/16/2005
Agilent has enlarged its family of DMMs and DVMs. The 34410A, 34411A, and 34405A widen the range of price and performance choices in the company’s DMM line, expanding on the popularity of the industry-standard 34401A. The 34410A and 34411A 6.5-digit meters provide greater reading speeds and system throughput, achieving more than 50 times the reading rate of the 34401A.
The 34410A and 34411A, which offer expanded connectivity through USB, LAN, and legacy IEEE 488 ports, comply with LXI (LAN extensions for instrumentation) Class C. The units also offer more measurement functions, expanded measurement ranges, more precise triggering, and as much as 1 Mbyte of reading memory. The 5.5-digit 34405A DMM, says a spokesperson, offers a new level of performance in its category as well as PC-standard connectivity.
“The 34401A has been very popular since its introduction in 1991, primarily because of its reliability, ease of use, and exceptional value,” says Scott Sampl, vice president and general manager of Agilent’s System Products Division. The $1595, 6.5-digit, dual-display 34410A benchtop DMM that is compatible with the Agilent Open System framework. The instrument, which is available now, takes 10,000 readings/sec at 5.5-digit resolution and measures dc and ac voltage and current, resistance, capacitance, frequency, and temperature. Accuracy at low and high frequencies is better than that of earlier-generation instruments. The unit has data-logger capability with storage of as many as 50,000 readings, and LAN, USB, and IEEE 488 connectivity.
The $1995, 6.5-digit, dual-display 34411A benchtop DMM, is also available now and is compatible with the Agilent Open System framework. The unit offers better performance than that of the 34410A. Additional features include reading rates as great as 50,000/sec at 4.5 digits, 1 Mbyte of reading memory, level triggering, and pre/post triggering. A peak-detection feature measures the amplitude of pulses as short as 20 μsec. High acquisition speeds allow the instrument to catch peaks that previous-generation instruments would often miss.
The 5.5-digit, dual-display 34405A benchtop DMM has standard PC-I/O capabilities. It will sell for less than $1000 and should become available in early 2006.
