  • Three-Stage Hetereodyne Mixer

  • Hybrid Super Heterodyne FFT

    Since FFT based analyzers are only capable of

    considering narrow bands, one technique is to combine

    heterodyne and FFT analysis for consideration of wide and

    narrow spans. This technique allows for faster sweep time

    This method is made possible by first down converting

    (mixing) the signal (super heterodyne), then digitizing the

    intermediary frequency and using FFT techniques to

    acquire the spectrum.

    One benefit of digitizing the intermediary frequency is the

    ability to use digital filters, which have a range of

    advantages over analog filters such as near perfect shape

    factors and improved filter settling time. Also, for

    consideration of narrow spans, the FFT can be used to

    increase sweep time without distorting the displayed

    future option from ADC

  • IQ Data Recording Function

    Sampling Rate identical to selected CBW

    Memory of max. 250,000 data sets: I and Q value plus resp. frequency value

    Maximum observation periods for RBWs of 32 MHz / 200 kHz / 100 Hz are: 7,8125 ms / 1,25 sec / 41,67 minutes, respectively

    Trigger functions of Scope Mode (as in SRM) can be used

    IQ data will be presented individually or combined over time

    When post-processing recorded data every part of content can be extracted from IQ data including contained user information itself (voice, video, FAX, data, telemetry, etc.) many 3rd party software is available for that purpose

    Constellation diagrams are very useful to present QoS or KPI of PSK or QAM modulated signals. In that case Q will be simply presented over I after carrier frequency was synchronized with symbol rate. Thus IQ data will be presented at their ideal sampling times in order to detect deviation or noise => distortion of time/phase or amplitude

    This analysis allows for simple signal classification, e.g. digital modulation, PSK-8 with symbol rate of 19 200 Baud OR analog modulation, FM with peak frequency deviation of 75 kHz

  • Gapless IQ data streaming up to 400 kHz BW

    Separate IQ data channel (TCP or UDP) and control channel (TCP)

    allow for change of parameters on-the-fly

    => e.g. user program is searching for max. signal level by modifying

    MR/Attn and/or Fcent and/or BW !

    - flag bits will indicate potential settling times (BW) if any !

    - time stamps are supporting this function, too

    => change of settings without data stream interruption

    addresses monitoring applications in a very comfortable way

    included in Scope and IQ data option

    soft codecs on controller PC demodulate data stream into baseband

    signal, e.g. for listening to analogue information (.wav)

    => lawful interception of voice/data/video

    => or continous QoS analysis of digital signals, i.e. KPI assessment

    like constellation diagram or EVM or Eb/NO

    New: IQ Data Streaming

  • Scope Remote with IQ Data

  • IQ Data of GSM DL Channel

  • IQ Data of GSM DL Channel


  • New mode for spectra with approx. 25 times more data points

    (27 k to > 600 k bins) => high res. trace data

    Alternatively 400 bins are also possible => for fastest testing

    => real-time control systems

    Application offers wideband analysis with multiple windows GUI

    based on a single sweep

    Multiple SA windows can be programmed by user,

    e.g. one per carrier / band can be realized

    N.B.: ITU-T Spectrum Monitoring Handbook asks for 12,5 kHz

    channels and respective analysis and presentation of bins

    => NRA/IDA/SRM offering dF=RBW/2 => e.g. 20 kHz => 2 x bins

    => approx. every 10 kHz one result point !
