    Default the most sharp LTE RF scanner, LTE interference checker in the world, DRT4311B

    the link also can search in ebay.

    DRT4311B already selected by all Chinese 3 operators (China Mobile, China Telecom, China Unicom) for their networks (LTE FDD, LTE TDD, WCDMA, CDMA2000, GSM) from year 2017, integrated the best scanner, we provide the total solution for the world, as for the scanner selection, you may have the basic knowledge of the scanner (scanning receiver):

    1. Superheterodyne detection is an old method for the receiver before, now, FFT technology already been implemented to the new scanner, with high receiving sensitivity (low than -134dBm, RBW=1KHz) and high speed (3000MHz/s) in same time, seamless scanning from 2-3000MHz, the wideband scanner’s band can be defined by customer within its range.
    2. scanner’s feature:
    we tested feature of the main scanner (wideband with MIMO) as attached, field and lab test in Beijing and Taipei:

    comp.rar

    3. scanner’s performance:
    During the LTE testing, RSSI,RSRP, RSRQ, RS-CINR, Time offset etc. are the basic measurement (maybe occupy 20% performance of a scanner), DRT4311B also can do the measurement for LTE (include FDD and TDD) each RE and each symbol:

    The LTE scanner must sync with GPS then get the correct time offset of each cell, it is very important for TDD LTE interference checking;
    Not only GPS, DRT4311B can sync the atomic clock, so the clock tolerance will less than 1E-8, we designed rubidium clock as following:

    Depends the atomic clock, DRT4311B can check the Doppler Effect when in the high-speed train.

    4. in some area for interference checking, you may need the integrated version of scanner, already integrated the battery, tablet PC etc. into a box:

    For the interference locating, you may need the following log directional antenna (500-7500MHz, 14dBi gain):
    5. the specification as following:
