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

It
clearly

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
