The HP 3403A True RMS Voltmeter covers a broad range of ac measurement applications. It is a true rms, 3-digit voltmeter which provides bench and systems capabilities. The 3403B provides six ranges of ac measurement and the 3403A adds five ranges of ac + dc for low frequency capability and five ranges of dc. In addition to the systems options such as BCD output and remote control, a dB display option is available to permit measurements directly in dB. Autoranging is also available as an option for the 3403A. The dc and 2 Hz to 100 MHz bandwidth of the 3403A will allow usage throughout the frequency spectrum. The 3403A is not only a general meter for audio and low RF use, it also can be used in the upper RF and IF bands. The 3403A, in addition, is a low frequency measurement instrument and a five range dc meter.
