DeepView – New Mask and Trigger Functionality

Together, the RFeye SenS Portable and DeepView software allow you to record high-fidelity, long-duration I/Q data. This could be hours or even days of data. However, what if the signal you are looking to record only occurs for a few milliseconds during a 24-hour period? You could wait until the signal appears (and potentially miss it) or maybe record the whole 24-hour period. Instead of creating terabytes of recorded data to search through, a new feature in DeepView allows you to record just the transient signals you are interested in when they occur. DeepView’s new mask and trigger functionality lets you trigger a recording on the SenS Portable using mask breaks.

Masking to Exclude Data

To trigger a recording, you first need to set the triggering threshold. This could be a simple fixed level trigger but if you have specific signals you want to ignore, or your noise floor is dynamic, a mask can be more useful. Masks let you exclude specific areas of the spectrum you want to ignore. You can hand draw a mask, or you can let DeepView create a tailored mask. You can set DeepView to dynamically learn what is “normal” for the part of the spectrum you are interested in. A mask can then be created a few dB above “normal”.

 

 

Triggering to Capture Data

Once you have created a mask, you can trigger a recording to start if a signal breaks the mask.  DeepView has some clever features to make triggering even more flexible and useful. You can specify if you want the system to re-arm after a mask break occurs and also how many times you want it to re-arm. So, for example, if set to re-arm three times, it will make a recording for the 1st, 2nd and 3rd time the mask is broken, and then stop making any further recordings.  Another great feature of the trigger functionality is the pre- and post-trigger buffers. To make sure you capture the full signal and any signal artifacts, you can tell DeepView to record data for a specified length of time before the signal starts and after the signal finishes.
