Gould 7074 Oscilloscope
Digital Storage Oscilloscope
Gould’s 4070 series of digital oscilloscopes have been designed with the user in mind. These highly sophisticated instruments are particularly easy to use. To obtain a trace is especially simple - just connect the signal and press the Auto Setup button - the 4070 does the rest. Having obtained a trace, three readily accessible cursors make ή easy to take timing and voltage measurements directly from the screen. The built-in plotter or an external plotter using HPGL can be used to make a hard copy of the display for future reference as well. For the more advanced user, the 4070 series have a great deal to offer. The GPIB(IEEE488) and RS423(RS-232) interfaces allows control by a computer, hence the Oscilloscope can be left unattended whilst it continues to take measurements and plot traces as and when required. All of the operating functions can be controlled by the computer and the Oscilloscope can output complete trace data to the computer for further analysis. The 4070 incorporates a Software menu system allowing functions to be easily accessed. For example, up to four control setups including attenuator, trigger, GPiB and RS423 settings can be stored in battery-backed memory for future use with the ‘Save and Recall Setups’ menu. The trigger menu allows the 4070’s triggering system to be controlled using a 'Trigger Configuration Diagram’. This is designed to mimic the way that most users think about complex triggering requirements. It displays a flow diagram allowing various conditional triggering options to be set and combined appropriately. Options include event counting, time delays, and trace B to wait for triggering on trace A. The Display menu allows control of some of the 4070’s most advanced facilities. For example, using this menu, it is possible to select the glitch detection function. This can be used to detect transients as brief as 5ns even on the slowest timebase ranges. It is also useful for alias detection in certain circumstances. Another option, particularly useful when a trace has been magnified in the X direction, is interpolation. The 4070 is able to perform rapid sine interpolation on captured signals. Points are calculated and inserted between the actual samples which make up the originally captured trace. The original trace data is not lost and the uninterpolated display can be retrieved at any time. The 4070 can also perform linear interpolation if required. The Oscilloscope is also fitted with a keypad Interface, allowing Gould waveform processors to be connected to provide extra functions. These include automatic measurement of risetime, overshoot and frequency.

This is a combined operating manual for both the 4072 2-Channel and the 4074 4-Channel Digital Storage Oscilloscope. Throughout the operating manual the following convention applies;- 4070 - refers to both the 4072 and 4074. 4072 - refers to only the 2 channel 4072, 4074 - refers to only the 4 channel 4074.
