General Description
The 7500TR PCM Demodulator, in conjunction with any phase stable receiver, provides the capability for real-time demodulation and analysis of standard or nonstandard TDM transmissions.
The 7500TR runs on the Windows® 2000 Professional operating system, with a user friendly GUI. General self testing is provided through a built-in-test-equipment (BITE) modulator.
The 7500TR has a programmable PRN descrambler for Self Synchronous and Additive PRN formats. The 7500TR can decode A-Law, Mu-Law, ADPCM, CVSD and Sign Magnitude encoded Voice Grade Channel (VGC). The unit provides for monitoring channel activity on digital and VU VGC channel displays.
