Hewlett Packard - 3437A

The Hewlett Packard 3437A System Voltmeter is designed for systems. It is a 3 1/2 digit high speed dc voltmeter with sample and hold. The standard unit measures dc volts, provides trigger delay, burst reading capability and Hewlett-Packard Interface Bus (HP-IB). There are three dc floating input ranges: 0.1V, 1.0V and 10.0V full scale with a maximum display of "1998." Sample and Hold allow the 3437A to be an instantaneous reading voltmeter.

The HP 3437A is a High Speed 3 1/2 digit HPIB Systems Voltmeter with sample and hold. It measures DC volts with input ranges of 0.1, 1, and 10 volts full scale. The sample and hold allows for it to be used as an instantaneous voltmeter. The trigger delay can be set from 0.1 microiseconds to 1.0 second and the number of readings can be set from 0 to 9999. The 3437A is HP-IB programmable and has two data output modes: serial ASCII out put and Packed output. The maximum reading rate varies from 3600 to 5700 readings per second depending on the data mode. The input of this unit is what appears to be a 3-pronged BNC connector, this is shown in the photo.
