Pickering Interfaces – Test and Measurement
“Pickering Interfaces is a market innovator in signal switching and conditioning for a broad range of applications and architectures with the largest range of switching cards in the industry for PXI, LXI, PCI, VXI and GPIB test solutions to users and integrators of modular test systems.”
Three Channel Function Generator
- DC to 10MHz
- Three Channels in One 3U Slot
- 48-bit Frequency Resolution
- Simple Generation of Repetitive ArbitraryWaveforms
“The 41-620 is a compact 3 channel function generator provided in a PXI 3U single slot module. It is capable of generating sine waves to 10MHz with 48-bit frequency resolution referenced to the 10MHz PXI clock or to an external standard.”
Shown on right is the 41-180 Programmable Attenuator Module. Mechanically switched attenuators used for conditioning the signal levels from devices under test and ensuring that other measuring instruments are operating close to their optimum operating point for noise and linearity.
