SINE FBI Charts
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.

SINE Sinusoidal Vision Demonstration Array
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)

Arbitrary Load Control For Modulation Distortion
S94570B
Extend the modulation distortion application by computing figure of merits such as EVM and ACPR for any desired load with arbitrary load control (ALC). Modulation distortion with ALC integrates the powerful capabilities of the PNA-X with an electromechanical tuner so a non-50 Ω load can be presented to the DUT and changes in device performance or sensitivity to varying load conditions can be accurately measured.

Gateway Inverse Function
InverTS
InverTS is ENENSYS’ DVB-T2 Gateway inverse function that de-encapsulates a T2-MI stream into one or several MPEG-2 Transport Streams over ASI and IP.The InverTS is designed to receive a single PLP or Multiple PLP T2-MI stream over ASI or IP in order to de-encapsulate the T2-MI stream into one or several MPEG-2 TS over ASI and IP. It outputs the MPEG-2 TS encapsulated by a DVB-T2 Gateway.The InverTS can also apply to a lot of use cases wherever applications require to retrieve the genuine and multiple MPEG-2 TS that are carried over the T2-MI stream. It can be operated for re-multiplexing a DVB-T2 stream with regular TS content or for simulcasting the same content over different networks.The InverTS is the ideal product to help monitoring a T2-MI stream either using its optional internal advanced monitoring tools or by connecting it to existing monitoring tools through ASI or IP. The Advanced monitoring option enables to supervise in real-time PLP bandwidth allocation, DVB-T2 transmission parameters and the MPEG-2 TS encapsulated within the T2-MI stream.
