It is not unusual for test systems to generate high voltage signals incompatible with the instrumentation capability in a PXI system. It is also not unusual for tests systems to be incapable of generating large enough voltage swings to simulate sensors or other devices that stimulate a device under test. The PXI chassis power supplies limit the capability of PXI devices to generate high voltage signals without space consuming power supply conversion.
Pickering offers PXI solutions for both these problems. The 41-180 is an accurate DC to 3GHz programmable attenuator that has a 1dB step resolution, allowing it to adjust signal amplitudes for optimum measurement by other devices. The 41-182 is a programmable attenuator with bandwidth between 10MHz and 6GHz available in triple or hex formats.

The 41-660 provides a convenient way of attenuating high voltage low frequency signals to levels that can be captured by other PXI devices without risk of damaging them.
The 41-650 provides a convenient solution for increasing the signal amplitude from waveform or function generators to permit them to simulate real life sensors.
All the connectors used by these modules are supported by a comprehensive range of cable and connector accessories.
