Figure 2: TekFlex active probe tips
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.
P77C292MM adapter
Use the P77C292MM, 2.92 mm adapter to connect a TDP7700 series probe to a DUT with 50 Ω test point connectors. 2.92
mm connectors are mechanically compatible with SMA connectors.

The adapter supports testing of serial standards such as HDMI, MIPI M-PHY, and DisplayPort; cables and retainer are
included.
