Description :

The DTMB (CTTB) measurement application is one of more than 25 measurement applications in the Keysight X-Series, an evolutionary approach to signal analysis that spans instrumentation, measurements, and software, transforming the X-Series signal analyzers into standards-based transmitter testers. The DTMB (CTTB) application provides fast, one-button standards-based power and modulation analysis capabilities to help your design, evaluation, and manufacturing of DTMB (CTTB) modulators, transmitters, amplifiers, tuners, and gap-fillers/repeaters. Using the optional analog baseband IQ inputs in the MXA signal analyzer, the DTMB (CTTB) application provides the flexibility to measure signal quality and modulation accuracy with RF input or analog IQ input.

  • Quote and availability
