Features

Versatility

The Model 8550 offers many features and functions. such as enhanced accuracy, eight different linear and logarithmic sweep modes, automatic phase lock loop, counted burst, and internal trigger generator. Besides its normal-continuous mode, Model 8550 offers a variety of interrupted and controlled modes. Tabor generators are reliable and easy to operate. Rapid, repeatable testing is assured by the user programmed non-volatile memory. Extremely broad frequency and amplitude limits permit usefulness in a variety of complex applications. Parameters are digitally set over exceptionally wide ranges:

Frequency - 10mHz to 50MHz
Amplitude - 10mVp-p to 32Vp-p
Pulse Width - 10ns to 999ms
Pulse Transitions - 5ns to 99.9ms
Sweep - 10mHz to 50MHz (8550)
Phase Lock Offset - 180°

Self-Calibration

Front panel calibration, even by inexperienced persons, has made maintenance and troubleshooting extremely easy. Output waveform parameters are compared to internal references and are stored together with correcting factors in special tables for later use. If the self-calibration routine fails to successfully complete, the generator produces a failure list that can be evaluated, anytime, either from the front panel or through GPIB reporting query. The self-calibration capability restores full accuracy potential - even at extreme temperatures (0-50°C).

Phase Locked Loop (PLL)

The phase lock feature automatically locks the 8550`s output to external signals at frequencies up to 60 MHz and voltages up to 40 Vp-p. Phase offset is programmable with 1º resolution, and accuracy of ±3º.

IEEE-488.2 Compatibility

The IEEE-488 standard greatly simplifies interconnection of programmable instrumentation. It clearly defines mechanical, electrical and protocol specifications. The IEEE-488.2 standard, has significantly improved definition of data formats, status reporting, and error handling. This new standard goes further and defines a set of common commands and common queries for easy and goes further and defines a set of common commands and common queries for easy instrument interchangeability between instruments made by different manufacturers. Models 8550 and 8551 fully comply with IEEE-488.2. The IEEE-488.2 standard, has significantly improved definition of data formats, status reporting, and error handling.
