FAB-3226 -
Ines GmbH
The FAB-3226 Digital Bit Pattern Generator connects digital ports to an user-defined FPGA logic. As the FPGA is user-programmable all kind of operation can be implemented: input, output, and closed loop operation where input and output are processed in real-time.

40 GHz, Dual-Transfer PXI Transfer Switch Module—The PXI‑2798 can route RF or microwave signals in automated test applications. Designed to operate with less than 1 dB insertion loss at up to 40 GHz, the PXI‑2798 appears almost invisible to signals at much lower frequencies as well. You can use this module for basic signal routing or inserting and removing components in a signal path. The PXI‑2798 is also well-suited for passing high-order harmonics from RF upconverters or routing multiple sources to RF downconverters.

26.5 GHz, 50 Ω, Dual-Transfer PXI Transfer Switch Module—The PXI‑2598 is a general-purpose switch module for routing RF or microwave signals in automated test applications. You can use this module for basic signal routing or inserting and removing components in a signal path. The PXI‑2598 is also well suited for passing high-order harmonics from PXI RF Signal Upconverter modules or routing multiple sources to PXI RF Signal Downconverter modules. You can use its onboard relay count tracking to predict relay lifetime and reduce unexpected system downtime.

The Sinusoidal Visual Demonstration Array is designed to demonstrate the Modulation Transfer Function (MTF) of the human eye. Its transmittance varies sinusoidally and increases in spatial frequency from 0.2 to 20 c/mm, following a logrithmic scale. The modulation increases linearly from top to bottom. One can see, in the image, where the visual contrast contour disappears which is the MTF of the eye. Ideally suited for teaching and demonstration, the Array is available on film mounted in glass (-G), or mounted in a 2″x 2″ projection slide.(-SL)

There are two SINE Sinusoidal arrays designed for FBI applications: the SINE M-13-60-S-RM and the SINE M-13-60-FBI Kit.The SINE M-13-60-S-RM was designed jointly by the Federal Bureau of Investigation, of Washington DC, and MITRE, of Bedford MA. The primary function of this Target is for computing Modulation Transfer Function (MTF) evaluation in live scanner fingerprint systems for conformance to Integrated Automated Fingerprint Identification Systems (AFIS) image quality requirements. The array is on reflective material measuring 16mm x 16mm with sinusoidal arrays ranging in frequency from 1.0 to 10.0 cycles per mm; with nominal modulation of the sinusoidal areas at 60%. The top and bottom rows are density scales, from 0.20 to 1.20 densities.The SINE M-13-60-FBI Kit consist of two individual components, the SINE M-13-60-1X-RM and the RR1-N-RM Ronchi Ruling grating.
