Promax Prolink 4C Premium - CN Rood

PROLINK PremiumHigh-performance spectrum analyserHigh accuracy, high-speed sweepThe PROLINK Premium series includes a batch of improvementsin spectrum analyser mode that makes it a highly usefultool in a large number ofapplications in telecommunications.These instruments combinethe advantages of high-accuracysystems, using the 'HighResolution' frequency sweepmode, with those of real timeanalysers, using the 'Aerialalignment' sweep modeHigh frequency resolutionThe adjustment of the minimum frequency range or Span onscreen has been reduced to 4 MHz in satellite band and 8MHz in terrestrial band. Using a measurement resolution filterof 50 kHz it is possible to perfectly view signals that were noteven possible to detect until now with this type of equipment.For example, in SNG applications for the transmission of datafrom mobile units, the satellite identification is through detectionof 'Beacon' signals at certain frequencies. These very lowpower signals, may be clearly observed on the screen ofPROLINK Premium series instruments.9High sensitivityAnother advantage of the PROLINK Premium series is itshigh sensitivity, which allows to measure very weak signals,even below 0 dB!V. This is an essential specification to measurethe Carrier/Noise ratio (C/N) of digital signals, in accordancewith the values demanded by current standards in differentcountries.Flexible amplitude resolutionThe PROLINK Premium series combines a wide dynamicrange of 50dB with a selectable reference level and a very flexiblevertical resolution of 2/5/10 dB per division. In practicethis allows to pick up signal variations on-screen that are notvisible on other meters.The pictures below show a very low power signal as observedon the PROLINK Premium and on another device.As you can see, only the PROLINK Premium clearly showsthe 'beacon' signal of a VSAT transmission.With another instrumentWith a PROLINK PremiumMaximum and minimum holdAn application of maximumhold could be the measurementof non-continuous signalssuch as those in GSMband. Minimum detectioncould be useful, for instance, toidentify interferences in ananalogue TV signal.Return channel coverage for Cable TV (**)In cable television it is very important to cover the return bandfrom 5 to 100 MHz, as these frequencies are used for theimplementation of interactive services (internet, pay TV, etc.).Together with the RP-100, the PROLINK Premium becomesa very powerful test set to quickly confirm the operation andresponse of the cables, amplifiers, etc. in a cable TV network.KmISM band coverage (accessories not included)There is a growing number of devicesusing the ISM band (IndustrialScientific and Medical) which operatesat frequencies of 2.4GHz and5.8GHz.Optional converters CV-245 andCV-589 allow to use PROLINKPremium instruments in spectrumanalyser mode for aligning aerials,detecting interferences, etc.(**) Except PROLINK-2 Premium
