Shunt measurements
Special care must be taken with shunt measurements. Typical shunt
measurements generate signals with an amplitude of only a few volts or even
mV. To prevent interference from higher voltage signals (up to 100 V) the
following guidelines apply:
Use only coaxial cables for all measurements.
l
If possible place the instrument as close as possible to the test object to
l
reduce the length of the coax cable.
Physically separate low voltage signal lines and high voltage signal lines
l
as much as possible. Do not combine them. When the high voltage signals
include high frequency transients these will easily cross over to the low
voltage signals.
HINT/TIP
The GEN DAQ Series instruments typically have a very high bandwidth. As a
result of this high bandwidth high frequency transients might show that have
never shown before. Use the filter to reduce the bandwidth to a physicaly
relevant value.
