The Pulse Instruments PI-41701 Low Noise DC Bias Card, along with other
stimulus cards, is designed for the modular instrument platform CompactPCI. This card is a 6U Eurocard size that will plug directly into
the CompactPCI mainframe.
As a test or design engineer you must have state-of-the-art tools to
test, characterize and verify your complex semiconductor devices and
circuit boards. The PI-41701 Low Noise DC Bias Card is one of the high
performance, low-cost test instrumentation tools being developed by Pulse
The PI-41701 is a dual channel bipolar DC Bias supply that can provide
an output current up to 100 mA per channel. The output voltage ranges from
–8 V to +8 V and features programmable current limits with LED indicators
and software interrupt to show/alert the user if the channel is in current
limit. This card has special filter circuitry to reduce the output noise
for those applications that require a low noise bias output.
there is a ‘D’ type connector that allows the introduction of
laboratory type supplies to reduce the noise further. To change from using
the internal power supplies to external power supplies requires
repositioning a jumper. The PI-41701 also has voltage and current sense
for remote measurement of the voltage and current levels. This sense
circuitry is accessed via banana jacks on the front board flange.
voltage and current can also be sensed with an 8-bit A/D converter and
sent over the bus. This A/D sense circuitry is meant for measurements not
requiring high precision. The output connectors are SMA.
