RTX130B Product Information
In the digital terrestrial broadcasting and cable environment, powerful RF-modulated signal generation functionality is required in a portable form factor for design, test, and maintenance.

The RTX130B QAM & VSB RF Signal Generator offers a flexible, affordable solution for design evaluation and conformance testing of digital video products conforming to the DVB-C / ITU-T J.83 standards, annex A, B, C, and ATSC (8VSB) standards for digital terrestrial & cable TV systems.

The RTX130B RF MPEG Signal Generator provides this functionality:

• Supports ITU-T J.83 standards, annex A (DVB-C), B, C, and ATSC VSB, for modulation of streams played from disk
• QAM modulation mode*1 of 16, 64, 256, and 8 VSB
• Frequency: 50 to 860 MHz in 12.5 KHz steps
• 36/44 MHz IF output
• RF Output Level, 45-58 dBmV in 1 dB Steps
• DVB-ASI/SMPTE310M & SPI transport stream input/output for recording and playout from hard disk
• With the RTX130B you can select the combination of RF modulation options required when ordering, and can add further modulation options when needed, protecting your original investment

*¹ Not all constellations are available in all QAM modes.

The RTX130B is the optimum tool for design and evaluation of consumer QAM & VSB equipment, such as set-top boxes and integrated televisions, devices requiring a directly modulated RF input. The RTX130B can also be used as a signal source for end-to-end broadcast system evaluation and maintenance.

As an integrated solution, RTX130B removes the need to purchase a separate transport stream generator, QAM & VSB modulator, and an up-converter to generate QAM & VSB modulated RF test signal. DVB-SPI and ASI/SMPTE310M interfaces are also provided as standard, allowing recording and play out of MPEG-2 Transport Streams.

The RTX130B offers continuous, error free transport stream looping for long duration play out, and PCR jitter insertion for stressing MPEG product designs. Users can continuously loop test streams, including updating of all timestamps, continuity counters, and time tables.

Ethernet network control functionality enables remote control of functions like Play, Record, Clock Rate, and PCR Jitter Insertion using the SCPI (Standard Control for Programmable Instruments) command set, allowing easy integration into ATE and automated broadcast environments.

An optional scheduler application enables the RTX130B to be used as a simple MPEG stream server for pre recorded broadcast and manufacturing test signal transmission.
