APPENDIX E
TIME SERIES RECORDING
E.1 Overview
The time series (TS) recording feature of the RVP900 provides end-users
with the ability to record and playback IQ data. In addition, operators can
record time series and then use their own "off-line" programs for
processing the data. The time series can be recorded directly on an
RVP900 or on a separate archive host through a gigabit network.
The time series recording is built on several software components:
- RVP900 TS API—Where time series reside in memory in the
RVP900.
- Tsexport—Grabs time series from the TS API and sends them over
the network through a UDP broadcast. Typically a gigabit network is
used for this.
- Tsimport—Receives UDP TS packets and recreates the TS API on a
local machine.
- Tsarchive (licensed separately)—Records time series to a local disk.
This can be on the RVP900 or a separate networked archive host.
Supports both archive and playback.
- Ascope Utility—Can be used in playback mode to view either raw
time series or processed results from the RVP900 processing
algorithms.
- Tsview Utility—Used to see diagnostic printouts of stored time series
files. The complete source code is provided for this to assist users with
writing their own applications.
Of these components, only the tsarchive software is licensed separately.
Customers are free to write their own TS record/playback software and still
take advantage of the network features such as tsimport and tsexport.
