The Return Path Test Generator (RTG-2) is designed for alignment purposes in the return path domain (5 – 65 MHz) of the cable network.

The RTG-2 can digitally generate any frequency in that range, with 25 kHz steps. Due to intelligent signal processing and filtering, the RTG-2 has a very high spectral purity.

The RTG-2 has a digital controlled output level which allows the user to select the desired level with great accuracy and repeatability for each frequency of the active list. Another excellent characteristic of the RTG-2 is its output level flatness of ±1 dB over the entire frequency range. With optional software calibration this can even be brought back to ±0,3 dB.

The functionality of the RTG-2 is project based programmed. This means that:
*   The RTG-2 has a pincode accessed supervisor menu.
*   The supervisor can program the RTG-2 with a number of projects.
*   the RTG-2 can only generate a carefully selected list of test frequencies per project as edited by the supervisor.
*   The field service engineer can only use the frequency list belonging to the authorised project.

The RTG-2 does not generate frequencies simultaneously but sequencially. The user can select every single frequency of the list or choose a sequencing mode to have them activated one after another, with a adjustable step timing.

A few other remarkable properties of the RTG-2 are the display screen and the battery charger. The display is of the latest technology. It is very bright and has very low current consumption. The battery charger is an intelligent type protecting the battery for wrong charging cycles. Charging is done very fast, 2,5 hours typical for an empty battery. The RTG-2 can be charged with any DC power supply of 12V, like a 12V car cigarette lighter plug, Or a 12Vdc 1A mains supply.
