Hi All,
I have a problem. Given below is a topology that i have.=20

I have a bidirectional bus which connects a FPGA to the CHIP. The
distance between them is 2 inches. Now to probe this bus, i have the
signals coming out to the right at a distance of about 6 inches. Note
that i am using active probes to probe this interface and there are NO
buffers on the line between the chip and LA probes. Now the problem is
that when the LA is plugged in I find that the strength of the signals
driven by the chip comes down from 3.3V to 2V. Without the LA plugged,
the signal strength remains intact. Could anyone help me in
understanding this? If a solution is possible to get around this, it
will be great.

Anand
