VSE-1100

• Noise Trace added to HyperSpectrum Heatmap o A new trace available when the HyperSpectrum Heatmap is active o Helps more easily identify the peak of a noise signal, especially under an active QAM carrier o Can be used on either Port 1 or Port 2 of the VSE • Total/Span Integrated Power of downstream channels o Automatically calculates the power of all the downstream channels being tested o Adjusts which channels are included based on those being viewed and tested o Measurement available in RapidScan and Performance Scan views • Test Point Compensation o AutomaticallyadjuststhedisplayedlevelsbasedonconfiguredTestPointtemplates o Easily select different templates while in each applicable mode o Can be applied to both Upstream and Downstream measurements Other changes made in the v2.5 release: • Level measurement consistency issue in frequency extension band above 1.1GHz • Empty Channel Plan label will no longer crash the iPad application • Better display of CW levels in a wide span when using markers • PAL-D analog channels are correctly detected • Channel Plan discovery date now displayed in the local time zone rather than UTC • Corrected possible 1dB level fluctuations with high levels

• Multiple Channel plans ○ Support up to 20 channel plans for each type 20x DOCSIS 20x Physical 20x Logical Channel Plan • Heatmap signal persistence display in HyperSpectrum mode • Insert & Delete custom CW channels into & out of currently active Physical Channel plan via AutoChannel’s right gear menu • CPI column added to Packet Table • Updated Performance Scan ○ Moved DOCSIS and skipped channels into their own section ○ Added formatting for numbers • Better differentiate between corrupt packets and bonded packets in Packet Table/Dashboard • Packets which fail to demodulate now impact CPI score • Better overview trace and higher resolution traces for HyperSpectrum • AGC updated to no longer AGC down after an overrange if the impacting signal is no longer active • Upstream Demod enhancement - will trigger under in additional circumstances, even if packet cannot be demodulated. • And other minor issues: ○ Corrected "MHz" label issue ○ Handles situation where duplicate files names are detected while saving ○ Sorting corrected by modulation, searching by 4 digit program number, and fixed frequency display for analog channels in AutoChannel ○ Corrected issue in Spectrum settings ○ Cleaned up error descriptions from Packet Table ○ Overlapping UCDs should draw more consistently

• Upstream Packet Table / Dashboard now show packets which are unable to be demodulated o Demodulation error, if detected, is shown / saved • NoiseTrak displays incrementing errored packet count if unable to demodulate packet • Packet number is now adjusted to better correlate to the packets in Packet Table • Performance Scan now saves the data in HTML as well as the CSV formats and can be exported to USB or synchronized to StrataSync for easier viewing • Added 256QAM Annex C as a valid channel type for detection and measurements

• Modified Performance Scan to now quickly populate the table with measurements from RapidScan, including Level, MER, and IUC allowing review of the results before saving it, or copying the data to CSV or HTML directly • Added ability to copy CSV from the save file screen for any mode • Added a way to delete all save files from the About menu, even files from other users • Improved Physical Channel Building on systems with FM channels • Mislabeled measurements in Performance Scan are now correctly labeled

Features added in this release: • Performance Scan added to RapidScan replacing the "Results" button o Measures Level, MER, Pre/Post BER, DQI, and other measurements across a selected frequency range o These results are placed into an easily consumable format for archiving or reporting • Long Term TimeTrak o Ability to switch between normal TimeTrak and Long Term TimeTrak o Long term will measure once per second, collect data up to 25 hours, and allow the VSE to measure without an iPad connected • Detection and level for DOCSIS 3.1 OFDM channels in 6MHz blocks • Video Analysis to analyze/record MPEG over IP via Ethernet • Spectrum reference added in Spectrum mode o Save the reference using the normal file save and then it will be accessible from the gear menu • Program names when present in-band for DVB Streams Other changes made in this release: • Updated branding from JDSU to Viavi • Re-ordered tabs based on use • Updated the USB protocol in accordance with Apple standards NOTE: iPad 2/3, though never officially supported via USB, will not work via USB after this update these older iPads can still be used over WiFi connections – speed of measurement updates may be affected o Recommend using an iPad 4, Air, or Air2 with USB • Support for VSEs with 1.8GHz measurement hardware – hardware availability to come later • TimeTrak now displays date/time • Changed TimeTrak CSV file to have timestamps in absolute times from negative milliseconds • Fixed an issue where statically configured Ethernet DNS server configuration wasn't persisted through reboot • Corrected 2 Pal BG channel numbers that were assigned to the wrong frequencies • Made it easier to press the buttons on the About VSE screen • Fixed display of uptime in About screen • Fixed a crash in BIST if it was run while the BCM was on • Fixed the drive name, if it wasn't set, it would be displayed oddly after a USB export/MPEG recording capture • Changed the "Min MER" display in the side bar to come from the "live" MER instead of the averaged MER • Fixed an issue where a channel plan with inaccurate information can keep the user from building UCDs/LCP because it will trust the info from the physical plan instead of just doing a channel detect at the user's requested frequency • Fixed a layout issue with BER Elapsed Time where it would be pushed off the screen after running a long time • Modified when the upgrade screen is displayed, so it won't be displayed when the application gets disconnected while connecting • Fixed marker boxes so if 2 had collided and one was partially visible, when bringing up the advanced controls to close it, the advanced controls will be always visible • Changed the format of the way Downstream physical and logical plans are saved so they load much faster o Both will need to be captured again after update • iPad application UUID is now able to be copied from the About screen where it's displayed Known issues in this release: • IP MPEG over Ethernet may have more issues than RF for recordings that require a large buffer (slow drive, large pre- trigger buffer) • If a menu is open when re-attaching to Long Term TimeTrak, simply tap outside of it, don’t choose something from the menu – this will cause the mode to stop measuring
