File Source Block

File Source block:

Import and playback any RTSA-Suite PRO ".rtsa", ".tag", ".dat" (I/Q, Spectra, Video, Tracking etc.), ".wv" and ".iq.tar" files from disk.

Powerful export feature to other file formats:

File Source Block | Import, Cut and Export data

Right hand side output:

  • Stream


This block is quite similar to the File Reader block but reads the complete file to RAM. This makes it interesting for fast playbacks or whenever high data transfers are needed. It can also read third party I/Q files as there are Waveform (.wv), R&S IQ.TAR (.iq.tar) and Text (.txt).


In addition the File Source block supports the following features:

  • Read any data format supported by the RTSA-Suite PRO incl. ".wv", ".iq.tar" and ".txt"
  • Change playback speed
  • Preview the datafile and conditions (spectrum, video-picture, antenna position etc.)
  • Area playback (mark an area within the preview for playback)
  • Varios playback options (once, loop, steady, contiguous)
  • Cut and save/export a marked area under a new file
  • Export the file or portions of it under a new data format (CSV, XML, JSON, RTSA, TAG, DAT, ASC and MAT)
  • Change/add power offset, time offset, location (GPS) etc.


The powerful export feature supports CSV, XML, JSON, RTSA, TAG, DAT, ASC and MAT (Matlab) formats:
