Geerjan, from the NetBeans Team, came across our Radio Monitoring Toolkit platfom. He wrote a little article on his blog about it. Check it out here.
Rohde & Schwarz EM100
The new Rohde and Schwarz EM100, which is a PR100 without screen or keyboard, has been added to our list of supported devices.
Our TETRA decoder @ Astrid Days
The FIT (Field Intervention Team) was showing the C.C.R.M.’s Tetra decoder on their stand at this year’s edition of the astrid days. They are very pleased with our products and services. Marc De Buyser, A.S.T.R.I.D.’s Director General, complimented Christophe and Geoffroy for this great tool.
C.C.R.M. team would like to thanks and congratulate A.S.T.R.I.D. for this great event!
Tetra presentation @ B.I.P.T.
The CCRM was giving a presentation for the BIPT yesterday. Christophe introduced the platform and talked more about the TETRA norm and our TETRA decoder module. Then, along with Geoffroy, he gave a quick demonstration of all the platform features and went into more details with the TETRA decoder.
The platform has great tools for monitoring and decoding RF signals. More specific presentations on other features can be planned. If you’re interested by a training or a presentation, leave a message here or write to platform at ccrmradio dot be .
Receiver info on Spectrum panel
The Spectrum panel has a property Frequency Click that takes a receiver, spectrum or IQ trace. If that property is set, the receiver frequency and bandwidth are visible on the displayed spectrum (assuming that the receiver frequency is in the spectrum span). The receiver is now frequency-controlled by a click on the spectrum.
PR100 – PScan
The PR100 can now send Panorama Scan as a spectrum trace. From the PR100 manual :
The receiver’s maximum FFT bandwidth of 10 MHz makes it possible to perform extremely fast scans across a wide frequency range (panorama scan). For this purpose, frequency windows of max. 10 MHz width are linked in succession, and thus the complete, predefined scan range is traversed. Same as with the IF spectrum, an FFT is used to process the broad window with a finer resolution. The width of the frequency window and the FFT length (number of FFT points) are variable and are selected by the receiver. In the panorama scan mode, the user can select among 12 resolution bandwidths from 125 Hz to 100 kHz. The resolution bandwidth corresponds to the width of the frequency slices (bin width) mentioned under “IF spectrum” above. Based on the selected bin width and start and stop frequency, the R&S®PR100 automatically determines the required FFT length and the width of the frequency window for each scan step. The receiver selects these internal parameters so that the optimum scan speed is achieved for each resolution bandwidth.
We will use this mode to perform band occupancy measurements.
Receiver window
The old receiver window has changed. The new one is fully integrated with the trace system and users can now see more than one receiver window on their screen!
Open a receiver window by double-clicking on a receiver trace. Or choose the menu Window->Traces->Receiver and drop a receiver trace on the panel. There is a field for setting the frequency step. Use the mouse wheel on the frequency field to change its value by steps. The demodulation field is hidden if it cannot be set (for example from an icom receiver).
Spectrogram
A new window is available : the Spectrogram. It takes a spectrum or occupancy trace as input and display the data on a time/frequency graph. The level is based on color scale.
Version 10.3
This version includes the decoding framework. All the modules versions have been updated too. The splash screen shows the version number.
Multiple Properties Windows
It’s possible to have multiple properties windows. You can see and change the settings of more than one instrument/decoder at the same time!
To open the properties windows, double-click on the instrument/decoder node in the explorer.
