arrangement.
DO NOT CONNECT COAXIAL CABLING TO THIS OUTPUT. The capacitance
of the cabling will reduce the dV/dt rates noticeably.
11.DIFF OUT Connector
. This two-pin header connector connects internally to the logic
output of the DUT (and the associated ground). This is the output that is monitored for
“glitches” caused by high dV/dt rates on the common mode voltage. It will mate to the
Tektronix P6246 differential probe, or to standard 0.1” header sockets. When using the
differential probe, install the probe so that the “-” side is on the top, and the “+” side is
on the bottom. A differential probe is used to help eliminate noise coupled from the
high-voltage signals. Please note that the P6246 has a maximum differential input
voltage range of 7V. If higher values of VCC2 are used, a different probe will be
required. If a non-differential probe is used, it is best to avoid measuring the low-
voltage “DIFF OUT” signal at the same time as a probe is connected to the “HV
PULSE” signal. Inter-channel interference in the probes and oscilloscope may
introduce significant noise on the low-voltage signal. Instead, measure the signals
separately, and use the memory storage function of the oscilloscope if you wish to
combine the signals on a single image.
