TekFlex solder-in tips. These tips use flex circuit material and provide soldered,
multi-point connections. They support full TriMode measurement capabilities
and full probe bandwidth. If care is taken during the soldering process, these
probe tips can be reused through multiple soldering operations. The small size
and low cost design are good for high interconnect density measurements.
Both P77STFLXA Flex circuit based solder tips and P77STFLXB Flex circuit
based DDR memory solder tips are available.
The first time the probe tip is detected, S-parameter data for the probe tip is sent
to the oscilloscope, and probe-tip specific DSP filters are generated. These filters
improve the measurement accuracy of high-frequency measurements.
P77STCABL. This optional tip provides a soldered, multi-point connection that
supports full TriMode measurement capabilities at full probe bandwidth. If care
is taken during the soldering process, this probe tip can be reused through
multiple soldering operations. In some applications the robust mechanical design
of the tip and flexible cable construction provides better usability, compared to
the lower cost flex circuit tips. The first time the probe tip is detected, S-
parameter data for the probe tip is sent to the oscilloscope, and probe-tip specific
DSP filters are generated.
P77BRWSR. The optional browser connects to the circuit using two input contacts
with very fine point tips. These tips have built-in compliance 0.02 in (0.5 mm)
and adjustable spacing 0.008 in to 0.210 in (0.2 mm – 5.3 mm). The input
contacts include an embedded damping resistor for optimum measurement
performance.
The browser tip can be held in place or can be used to make hands-free
connections to the DUT when using the Browser Tri-Pod accessory, or a probe
positioner, such as the Tektronix PPM203B. The browser includes multiple sets
of S-parameters based on the spacing of the tips. The spacing is monitored and
the correct set of S-parameters are automatically used.
