The Gould 1600 digital storage oscilloscopes have been designed to provide a versatile range of instruments for use in a wide range of applications. The 1600 can operate in storage or non-storage mode (digital or analogue mode) as required and includes all the features expected of an advanced modern oscilloscope at the same time retaining user-friendliness. For the first time user, obtaining a trace is especially simple — just connect the signal and press the Auto Setup button — the 1600 does the rest. Having obtained a trace, three readily accessible cursors make it easy to take automatic time and voltage measurements directly from the display. The innovative use of five-position paddle controls instead of dials makes precise control of the instrument possible, the digital readout on the display constantly showing the current status where appropriate. More advanced features of the 1600 include a comprehensive system of menu-controlled functions. For example, the Acquisition/Trigger menu operates features such as the glitch detection function and the trigger delay, division and pre-trigger display functions. The pretrigger display function allows the signal immediately prior to the trigger point to be captured and displayed. Another menu-controlled feature of the 1600 is its memory. Two complete traces can be stored for future use, and four complete front-panel control setups. With the optional battery backup facility, these can be retained even when the 1600 is switched off. The 1600 comes complete with serial-channel and four-parallel channel analogue outputs for use with external plotters as standard. Optional extras include GPIB (IEEE488) & RS423 input/output ports for external control by a host computer, and Gould waveform processors to provide enchanced measurement and trace processing.
