The N5445A browser head (30 GHz) is the best choice for the
general-purpose trouble shooting of differential signals with
spring-loaded tips and variable spacing from 20 mil – 125 mil (or 0.5 mm
– 3.1 mm). The span between the signal tips is easily adjusted with a
thumb wheel on the browser (see Figure 10 ).
Using the LED
Headlights
A pair of LED headlights are integrated into the tip of the browser to
illuminate the probing area for better visibility. The headlights are
controlled via the Light button on the InfiniiMax III probe amplifier (see
Figure 1 on page 6). Pressing this button turns the headlights on / off
while pressing the button and holding it down ramps the intensity of the
headlights.
Adjusting the Tip Span
The thumb wheel on the browser (see Figure 10 ) is used to adjust the
spacing of the tips between 20 mil – 125 mil (or 0.5 mm – 3.1 mm). Stop
adjusting the span of the tips when the end of the range is reached and
do not force anything.
