DRM Broadcasting monitoring Software RXTEST
RXTEST was designed by Norbert Schall.
This package contains the last compiled Version of DREAM
This software has been initially designed to test the remote control of receivers to be used in SIOFST and other software like SCANNER, GPSMEAS, BANDSCAN etc., developed by N.Schall , ex Deutsche Welle.
At this stage it has been extended to facilitate DRM scheduled and interactive operations. The Database can be imported from a HFCC-formatted file and then will be displayed as a graphical representation.
The software makes use of the DREAM dreamloglong.csv and merges the data with signal strength measurements for 1 second intervals.The interactive mode allows a "click and shoot" selection of the frequency to be monitored. The Software will tune the receiver and start DREAM with the appropriate parameters. At the same time the signal-strength is measured in 1 second intervals.
2 scheduled modes allow automatic unattended reception and logging of DRM-transmissions in terms of availability and signal strength.
1. Mode is a daily mode that will allow to monitor similar entries on a daily basis daily schedule
2. Mode is a weekly schedule that allows different entries for every day of the week weekly schedule
During automatic measurements a 15 minutes history of the signal strenght can be displayed
Several Receivers are supported, the list will be updated as more receivers become available configuration
After each scheduled sequence the program generates Layer3,2,1 and Layer 0 files which can be used for evaluation with EXCEL .
The files are Comma-separated and contain a headline.

Basis for the evaluation and the layered approach is the SRO-code which is to be intended similar to the well known SIO-code for analogue reception.
R in this case describes the classification of the SNR value in 5 db increments.
Example: R3 means SNR= 15 to19 dB
