MODELS 8550/1 50MHz Single Channel Pulse Function Generators • Improved replacement to HP 8116A. • Changing pulse levels in less than 6ns • Four instruments in one: Function, Pulse, Phase and Sweep (8550) Generators • Linear transition times are independently programmable for trailing and leading edges • Popular output waveforms including sine, triangle, square, pulse and DC (8550) or ramp (8551) • Control inputs for FM, VCO, and AM modulation • Pulse output waveforms include: normal pulse, xed duty cycle pulse, and pulse complement • 30 storable, non-volatile, front panel set-ups • Control input is available for pulse width modulation (PWM), AM, VCO, and FM 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. Model 8551 is a pulse/function generator, which has performance characteristics similar to the Model 8550. In addition, this instrument offers pulse and ramp waveforms as well as their complements. Model 8551 also provides an accurate control over pulse parameters and pulse transition times. The variable rise and fall times may be independently adjusted within common ranges. Linear and logarithmic sweep functions are not available on this model. Output waveforms may be gated, triggered, or may generate a burst of pre-selected • Auto calibration and built-in self diagnostics • Standard GPIB interface number of cycles. The generator also provides a number of externally controlled modes, including VCO, FM, AM, and PLL. Versatility 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 selfcalibration capability restores full accuracy potential - even at extreme temperatures (0-50°C). IEEE-488.2 Compatibility The IEEE-488 standard greatly simplies interconnection of programmable instrumentation. It clearly denes mechanical, electrical and protocol specications. The IEEE-488.2 standard, has signicantly improved denition of data formats, status reporting, and error handling. This new standard goes further and denes a set of common commands and common queries for easy and goes further and denes 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 IEEE488.2.
