Model 8550 Function Generators - Tabor Electronics - #1

MODEL 8550

• Direct replacement to HP 8116A.

• Four instruments in one: function generator, linear sweep generator, logarithmic sweep generator, and phase locked generator

• Auto calibration to typically 1% accuracy on all functions, 0.1% continuous frequency accuracy. Built-in self diagnostics

• Six popular output wave forms including Sine, Triangle, Symmetrical Square, Positive and Negative Square waves, and DC

• 30 storable, non-volatile, front panel set-ups

• High-resolution, high-accuracydigital settings. Parameters are set, either from the front panel or through theGPIBinterface

• Control inputs for FM, VCO, and AM modulation

• Accurate sweep operation is digitally controlled with the provided X ramp (horizontal drive), and Z intensifier (marker) outputs

• Standard GPIB interface, complies with IEEE-488.2 specifications

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 stand and 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.

Model 8550 is an extremely high performance programmable function generator. It provides a variety of signal waveforms to be used as test stimuli for a diversity of electronic devices. For improved immunity to RFI and EMI noise, the instrument is housed in an all-round metal case. 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. Output waveforms may be gated, triggered, or may generate a burst of pre-selected number of cycles. The generator also provides a number of externally controlled modes, including VCO, FM, AM, and PLL

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 - from 10mHz to 50MHz

• Amplitude - from 10mV to 32V

• Pulse Width - from 10nsto 999ms

• Pulse Transitions - from 5ns to 99.9ms

• Sweep - from 10mHz to 50MHz

• Phase Lock Offset -180°

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 rom the front panel or through GPIB reporting query. The self-calibration capability restores full accuracy potential - even at extreme temperatures (0-50 C).
