Model 8020

20MHz Single-Channel Function Generator

Model 8020 is a high performance Function Generator. The instrument features six standard functions: Sine, Triangle, Square, Positive Square, Negative Square and DC waveforms. Its parameters are digitally controlled over extremely wide ranges normally not found in such instruments. The generator features a bright LED display which is clearly visible in any lighting conditions. Operating model 8020 is very easy, in-fact, first time users rarely need guidance. Using standard off-the-shelf components, sockets and plug-in board construction, model 8020 is easy to maintain. Installable GPIB interface upgrades model 8020 to full system performance.

Using the microprocessor technology, the Tabor 8020 provides reliability and ease of operation in either manual or GPIB-IEEE 488 modes. Modification of parameters is digitally set over exceptionally wide ranges:


The 8020 employs a built-in frequency counter. This counter is incorporated in an internal closed loop which constantly monitors the output frequency. When deviation from the programmed frequency is sensed, the counter instantly sends correcting data to the microprocessor. Utilizing this procedure enhances the basic frequency accuracy to 0.1% -an uncommon figure in such a class of instruments.

Production Environment

Rapid repeatable testing every time is assured by special features, which reduce the potential of operator`s set-up error.

Easy to understand panel layout and positive action buttons simplify operation even for less skilled user. Error messages in the readout warn of possible operator mistake.

Any of 30 pre-programmed complete setup states, stored in a non-volatile memory can be recalled by a simple number, ensuring exact duplication of previous set-up no matter how complex. This feature saves a lot of time which is otherwise required to set up the instrument for different tests.

All controls -choice of waveforms, setting of modifiers, and wave form output disconnect -are programmable through the GPIB interface (talker Listener Interface)/

The last set-up state is automatically established on power turn-on, weather the power is off momentarily, over night or longer, ensuring exact continuation of the previous test. Storage of parameters include GPIB address is by a non-volatile memory.

During system check-out the unit provides an error status report which may be recalled using the serial polling sequence.
