Model 8021

20MHz Single-Channel Pulse Function Generator

Model 8021 is a high performance Pulse/Function Generator. It provides the basic features and functions as does the Model 8020. Additional waveforms include Positive and Negative going Ramp, Pulse and Pulse complement. Pulse width and Ramp width ranges are controllable within an extremely wide range of 25.0nS to 9.99S. Its versatility ensures a broad range of applications especially where complete control over pulse or ramp parameters is required. Rapid, repeatable testing is assured by thirty non-volatile front panel set-ups which give exact reproduction of previous tests no matter how complex.

Using the microprocessor technology, the Tabor 8021 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 8021 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.
