Bird - The RF Experts
Signal Analysis Took Kit Spectro-X


  • Simultaneously view and analyze up to 4 spectrum files (channels), with each channel displayed in frequency, time, and magnitude plots chosen by the user.
  • Play back all or a portion of a file.
  • Visualize the amplitude summary of entire capture files.
  • No limitation on file duration.
  • View Spectrogram and View Time Domain Plots windows provide high-resolution snapshot of transient events.
  • Pulse Search characterizes the pulse trains using pulse descriptor words (PDW).
  • Carrier searches can be used to identify all stationary carriers over a specified time range.
  • Arbitrary Waveform Search will identify unique waveforms from a single reference or a library of signals.
  • Support for multiple input and export file types.

Item No
Carrier Search
Types: CW and stationary modulated carriers.
Options:  Power: ≥dBm, dB above noise floor. RBW: auto select, user-selectable. Search windows: Start time, stop time relative to start time. 
Results: Number of matches, carrier frequency, bandwidth, start time, duration, power. Prune results: saved results file, next search. Prune IF (matching carrier): frequency, bandwidth, start time, duration, or power (≥ or ≤ user-specified value), inside or outside user specified range
Waveform Search
Types: Search to match user-specified saved reference waveform, I&Q time domain matching
Options:  Correlation level, high selectivity filter, reference waveform (one or many), frequency shifting modes (auto or manual), time parameters. Reference waveform at f1, capture file at f2, shift (f2-f1). Included Waveforms EDGE, IEEE-802.11a/g, LTE, normal, extended prefix, 1.4, 3, 5, 10, 20 MHz.
Results: Number of matches, carrier frequency, start time, confidence, Waveform File
Pulse Search
Types:  Search and quantify pulsed waveforms in capture file
Options: Detection threshold power level, start and stop time for search, compute pulse frequencies, smoothing number of points.
Results:Peak power, average power, start time in file, width, PRI, rise time, fall time (10% to 90% referenced to detection threshold power level, phase, frequency. Sort results by any results parameters. Prune results: from saved results file, next search. Prune (matching pulse): peak power, average power, start time, width, PRI, and frequency (≥ or ≤ user-specified value), inside or outside user specified range).
Zoom Functions
Analysis Windows:  Left mouse click and drag to define zoom box, expand X and Y axes to limits of box, zoom/unzoom and plot type.
Playback inputs:  Zoom box defines start and stop times of next file playback.
Plot Types
Playback Time Overview:  Magnitude versus time, for entire file
Scrolling Time Domain:  Magnitude versus time, for current playback view.
Current Time Domain: Magnitude versus time, phase versus time, unwrapped phase versus time, imaginary versus time, real and imaginary versus time.
Scrolling or Static Spectrogram: Time versus frequency with color-coded power, time in vertical access waterfall display with most recent time on top, power displayed as color gradient, user-selectable range of power display.
Persistence spectrum: Visual accumulation of magnitude versus frequency over time, user-selectable persistence decay rate (infinite, slow, medium, fast).
File Playback
Direction and Speed:  Playback time overview, play, reverse, stop, jump, double speed, half speed. Minimum time increment (441 x sample rate).
Time and Scaling:  Program auto-select or user selectable playback start and stop times, time increment, jump time, spectrogram Y axis plot size, persistence spectrum Y axis plot size. Frequency domain plots (upper and lower frequency limits, absolute or relative center and span, number of points between limits). Resolution bandwidth and resolution time width, magnitude (maximum and minimum values).
Data Access
Input:  .xdat, .xiq, .bin, .tiq and columnar ASCII (.txt or .csv) Save and Copy:  Search results, program setup, intermediate spectrogram, persistent spectrums. Copy and plot any main window as JPG file Export:  .xdat, .xiq, .bin, .tiq and .mat with selectable time parameters, filtering, frequency shifting, and/or decimation.
Hardware Requirements
Windows 7 PC (64-bit), 120 Mbytes available on OS drive (>100 GB recommended for storage of playback files), 2GB RAM minimum
