Theory of operation
Introduction
The P7700 Series TriMode Probes are designed for use with MSO/DPO70000C
and newer oscilloscopes. Four P7700 Series TriMode Probe models are available
with bandwi
dths from 8 GHz to 20 GHz. MSO/DPO70000C oscilloscope models
are available at comparable bandwidths. These probe and oscilloscope models
feature the high performance TekConnect intelligent probe interface. P7700 Series
probes must be operated with an attached P7700 Series probe tip. Several P7700
Series probe tip models are available to support different application requirements.
The P7700 Series probes and probe tips contain device-specific S-parameter data
that, when transferred to the host oscilloscope after the initial c onnection is made,
create unique system DSP filters. These DSP fi lters optimize high frequency
perform
ance of the probe and probe tip signal path.
The P7700 Series probes are optimized for high bandwidth; they are not
genera
l-purpose probes. The P7700 Series probe solder tips that can be used
with the probes are miniaturized for electrical characteristics and acce ss to dense
circuitry, and must be handled carefully.
