The PROMAX PROMAX-12 Cable TV Multi-Standard QAM Analyzer incorporates measurements for installation, verification, and maintenance of reception and distribution systems for FM radio, MATV, CATV, MMDS, and includes the sub-band or return path.
- Functions: Level meter, Logger, Scan, Tilt, Spectrum analyzer, Transient detector, Cable digital analyzer
- Digital Measurements: Channel power, C/N, Bit Error Rate Pre-BER, Post-BER, MER, DVB-QAM constellation
- Tuning range: 5 MHz to 1005 MHz
- Analog channels: Signal level measurement on video carrier
- Digital channels: Channel power measurement by integration through channel bandwidth
- MER (Modulation Error Rate) measurement range: 26 dB to 40 dB
- BER (Bit error rate) measurement range: 10 E-2 to 10 E-8 (low resolution) E-9 (High resolution), E-10 in Continuous mode
- Constellation diagram: DVB-QAM signals (Annex A/B/C) and DOCSIS/Euro-DOCSIS
- Modulation type: QAM 16/32/64/128/256 ITU J83 annex A/C, QAM 64/256 ITU J83 annex B and QPSK
- Digital channel power: Channel power measurement, carrier/noise, BER and MER
- MER is essential for determining digital signal quality
- Data logger: Acquire and internally store required measurements for later review
- Print or transfer data logger measurements to PC
- Scan: See all channels of selected channel plan graphically with associated signal levels
- MARKER can be placed on any channel in order to find frequency or signal level
- SPAN and REFERENCE LEVEL can be changed in order to adapt presentation to user's test requirements
- Constellation: Constellation diagram allows graphic evaluation of received signal quality; aspect of on screen diagram will depend on digital transmission characteristics
- Spectrum Analyzer: Essential to solving cable modem related problems and very helpful for interference and noise troubleshooting, both in forward and return bands
- HOLD function maintains MAX and MIN values: Helpful in identifying interfering signals, for example, in return band
- Return path: Also includes return path spectrum Analyzer with max hold function for testing of cable modem transmission at subscriber premises, allowing to test upstream generator of subscriber cable modem
- Tilt: Provides graphic and numeric representation of absolute level of any 4 defined pilot frequencies and differences between two
- Intermodulation (CTB/CSO): Composite Triple Beat (CTB) and Composite Second Order (CSO) are indications of level of interference in television channel generated by intermodulation of signals from other channels (usually, other channels from same system)
- Over certain level CTB and/or CSO interference becomes visible on television signal
The PROMAX PROMAX12 Cable TV Multistandard QAM Analyzer is perfect for telecommunication installers since it integrates several functions: Level Meter, Datalogger, Scan, Tilt, Spectrum Analyzer, measurement and type of voltage (AC/DC) detection, HUM and Cable Digital Analyzer. It is an excellent tool for the installation and maintenance of analog and digital television signal reception/distribution systems working in the 5 to 1005 MHz range, including FM radio, community TV systems (MATV), cable TV (CATV) and wireless cable TV (MMDS), and sub-band (return path).
The PROMAX-12 incorporates the power level measurement function in the whole frequency band, which is very useful for checking a possible input saturation of some broadband demodulators and optical transceivers. In addition, with the HUM function is possible to detect a modulation at low frequency that affects the carrier and produces a distinctive hum in both image and audio.
The Datalogger function allows up to 55 loggers or measurements to be taken and stored, each with carrier levels, C/N and V/A ratios and channel power or MER of up to 140 channels. The measurements obtained can be checked on the equipment or transferred to a PC via the mini-USB connector.
In Scan operating mode, the PROMAX-12 indicates the level of all channels present on the band in a bar-graph display. The span and reference level are user definable. A moving marker shows the exact level of each specific channel.
In Tilt operating mode, the screen shows - both graphically and numerically - the difference in levels between any four previously defined pilot frequency channels, in order to obtain a qualitative measurement on band equalization.
As a Spectrum Analyzer, the PROMAX-12 provides an analysis of the entire band, with a span defined by the user from 1 to 100 MHz. Furthermore, it is possible to alter the reference level and detect and maintain the maximum and minimum values for INGRESS measurements.
The HUM mode measures the frequency and the value (%) of the HUM, which is a low frequency modulation that affects carriers and produces a distinctive hum in both image and audio, especially in analog signal. At the input, this function also identifies the voltage type (DC or AC) automatically, the voltage, and the frequency (only for AC).
In designing the PROMAX-12, special attention was given to building a multipurpose, accurate, yet easy-to-use instrument. A simple keyboard gives direct access to the various operating modes and, once in them, any measurement parameter can be easily changed using the rotary selector/button.
