CABLE TV ANALYSER PROMAX-12 * FROM 5 TO 1005 MHz * BER & MER ON QAM DIGITAL SIGNALS * MULTISTANDARD: 16/32/64/256 QAM ANNEX A/B/C QPSK * ANALOGUE CHANNELS * DIGITAL CHANNELS * BROADBAND POWER DETECTION * SCAN * C/N, CSO, CTB, VAC VOLTAGE, HUM * MAX AND MIN HOLD * CHANNEL POWER BY INTEGRATION * TILT * DATALOGGER * PRINTING * CONNECTION TO PC Digital channel power Just pressing a button, the channel power measurement, carrier/noise, BER and MER can be carried out. MER is an essential measurement, because it is useful to determine the digital signal quality. The constellation diagram allows to evaluate graphically the received signal quality, the aspect of the on screen diagram will depend on the digital transmission characteristics. Spectrum Analyser It can be essential to solve cable modem related problems and very helpul for interference and noise troubleshooting both in the forward and return bands. The HOLD function maintains MAX and MIN values: this is of great value for identifying interfering signals, for example, in the return band. Data Logger The PROMAX-12 can acquire and internally store the required measurements for a later review. It also can print them or transfer the measurements to a PC. Scan In this mode we can see all the channels of the selected channel plan graphically represented with their associated signal levels. A MARKER can be placed on any of the channels displayed on the screen in order to find their frequency or their signal level. The SPAN and the REFERENCE LEVEL can be changed in order to adapt the presentation to the users test requirements. Tilt Return path It also includes return path spectrum analyser with max hold function for testing of the cable modem transmission at the subscriber premises, allowing to test the upstream generator of the subscriber cable modem. The Tilt function provides a graphic and numeric representation of the absolute level of any 4 defined pilot frequencies and the difference between two of them. An interesting application is found in the return path where the PROMAX-12 together with the RP-110 Pilot Generator will permit to evaluate the frequency response in a graphical and comfortable mode

CABLE TV ANALYSER PROMAX-12 Intermodulation (CTB/CSO) The Composite Triple Beat (CTB) and Composite Second Order (CSO) are an indication of the level of interference in the television channel generated by intermodulation of signals from other channels. Usually, other channels from the same system. Over certain level CTB and / or CSO the interference becomes visible on the television signal. Language It can be selected among English, French, German and Spanish. optional accessories Mains Power Adapter, Mains cable, Soft Carrying bag, F/F Connector Adapter, Rubber Shock Protector.
