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 Instruments.

Instrument Description

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. 

Additionally 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. 

The 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.
