This latest code level release addresses a number of minor enhancements and updates to the Differential Signal Analysis (DSA) and RF Spectrum Display (RSD) reference level calculation sub-system. The range calculation is now symmetrical and the 0dB reference line is marked in a different colour. The displayed DSA traces in the differential window now display the actual differential trace color for better situational awareness. The minimum differential range is now calculated as +/- 5dBm which eliminates displayed noise in extreme zoom conditions. We have implemented a click and drag measurement tool within the DSA (differential) display window. Clicking the left button and dragging the cursor across the DSA display shows a white arrow with legend showing the delta for frequency and dBm along the direction of the arrow vertically or horizontally over the display.
