browser and accessories (Pen
wand and hands free Tri-Pod)
The browser connects to the
circuit using two tips with very
fine point tips. These tips have
built-in compliance (0.02”,
0.5 mm) and adjustable spacing
(.008-.210” (0.2-5.3 mm)). The
browser can be held in place with
a hand or can be used with the
hands free Tri-Pod accessory or a
probe positioner such as the
Tektronix PPM203B. See Making
single ended measurements using
the P77BRWSR P77BRWSR
differential probe tip on page 25.
The browser is a differential only
probe accessory, but can be used
to measure ground referenced,
single-ended circuits as well.
When measuring a ground
referenced signal, connect the A
side (positive) input to the signal
to be measured and the B side
(negative) to the ground
connection.
If a probe tip breaks, it can be
easily replaced. See Browser tip
replacement on page 41.
Flex circuit based solder tips
The flex circuit based solder tips
are connected to the circuit using
thin (38 AWG) wire connected to
the vias on the tip. The steps to
follow when soldering the tip to
the circuit are shown in the
soldering procedure section
below.
The flex circuit based solder tips
support TriMode operation. To
use TriMode, a minimum of three
connections are needed, the A
and B side inputs and one of the
ground connections.
