The HP / Agilent 3478A provides a low cost, full function, reliable Digital Multimeter for system measurements. The 3478A offers selectable 3-1/2 to 5-1/2 digit resolution and 5 autoranging functions for flexibility in automated testing. The 3478A can measure DCV, true RMS ACV, 2- and 4-wire ohms, and dc and ac current. Simple, fast electronic calibration eliminates all mechanical adjustments to provide a lower cost of ownership. Selectable speed and resolution provide the right capability for your measurement. The 3478A can perform production tests or acquire experimental data at 90 readings/s with 3-1/2 digit resolution, or take 35 readings/s with 130 dB of noise rejection using 4-1/2 digits. The 5-1/2 digit mode offers 100 nVdc and 100 µW resolution for precise measurements. True RMS with 300 kHz bandwidth and 4:1 crest factor provides reliable measurements of ac signals. Fast autoranging makes the first reading useful and accurate.
