N O T E The specifications and performance plots of the N2836A solder-in probe head were
measured with a nominal spacing of 40 mil (1 mm).
In order to achieve the proper response (as shown in the performace plots), you need
to keep the mini-axial lead bodies roughly parallel and use the tip wires on the
mini-axial leads to get the desired span.
If you need to position the mini-axial lead resistor bodies different than this (that is,
resistor bodies close together or spread way apart), use Precision Probe to perform
an AC calibration of the probe; the AC calibration will capture the response properly.
Increasing the spacing to 250 mil will degrade the performance some, but Precision
Probe can be used to compensate or qualify the effect.
C A U T I O N The axial resistors on the N2836A solder-in probe head are fragile. They must be
manufactured in this way in order to meet the high-performance, high bandwidth
applications they are intended for. Be careful when handling.
For instructions on soldering the N2836A solder-in probe head into a
device under test (DUT), see
III Solder-in Probe Heads"
The axial resistors on the tip of the N2836A solder-in probe head can be
replaced if they break or become damaged. See
