That way it goes from Pending Deploy to Deployed in StrataSync instead of stopping at Pending Confirmation until the user syncs • Synchronized VSE/iPad version display. It’s now in the format {Major Number}.{Minor Number}.{Patch Number}-{Build Number} • Restored analog channel type display in the single channel side bar for Analog channels. • Modified DCII PID typing so that it is only set if the PID hasn't already been set to another type (except for SCTE-65) • Fixed an issue where RapidScan channel bars wouldn’t draw if the user was zoomed in to a single channel that would cover more than the full span. • Fixed an issue where logical build couldn’t continue from the frequency choice after coming back from a deeper choice • Modified the busy indicator to have a pale white background so it shows up better on a black background • Fixed a formatting issue that caused the frequency to be rounded to the nearest whole number and saved that way when capturing DOCSIS or Logical Channel Plans • Fixed an error where service ID and logical channel number were interchanged on AutoChannel

Video Analyzer Option The major feature addition for VSE-1100 v2.0 is the “Video Analyzer” capability. This is a RF QAM MPEG Transport Stream Analyzer that performs TR101-290 testing at multiple levels. An Event Logger and a Transport Stream Recorder are also included. The Video Analyzer seamlessly integrates with the previous RF measurements and makes it quick and simple to go from the service layer to the physical layer. AutoChannel™ The AutoChannel capability has been greatly expanded and brought out to a separate tab. It now compares and contrasts the Physical Channel Plan (RF) with the Logical Channel Plan (the channel information that is sent to the Set- top-box). AutoChannel also now provides a single location to build and track the channel plans (Upstream UCDs, Downstream RF and Downstream Logical). Saving Measurement Data – File Save Now when the user saves a measurement file a context specific dataset will be saved along with increased metadata and measurement snapshot. The format of the dataset is an easy to use *.csv file format that can be accessed through StrataSync or saved directly to a USB drive. GUI changes There have been a number of Graphical User Interface improvements implemented with v2.0. These include improved button designs on every tab, Channel Info increment and decrement channel buttons – to make it easier to go up or down a single channel step in the Downstream tools. Packet Table legibility has improved with color and layout changes. The Upstream NoiseTrak™ Wizard also has an animated connection diagram to simply the connection and measurement sequence. Other Improvements • DOCSIS Channels are now highlighted • Improved upstream packet detection on RFOG networks • Improved DQI to work at lower signal levels • Portuguese language improvements • German language improvements

•Improved Chinese Language Translations •Improved Portuguese Language Translations •Improved connection robustness after application is placed in background

VSE 1.1 includes the following: •Added support for high bandwidth Cisco conditional access tunnels in the Logical Channel plan capture. •Added support for HRC system lowest channel detection. •Added iPad App version number when syncing. App version number is now available in StrataSync for use statistics. •Added Portuguese translations. •Addressed an issue where an invalid static IP address configuration for Ethernet would prevent communication with the VSE. •Added a way to configure a DNS server for Ethernet when Ethernet is statically configured •Several small UI fixes for displaying localized text. •Fixed an issue with channel selection for frequency markers in the Downstream Analyzer. •Fixed an issue that would intermittently prevent successful DVB logical channel plan captures. •Improved analog channel identification in the channel plan build. •Fixed an issue where the VSE may not necessarily automatically restart after an application crash. •Fixed an issue where if an update was downloaded, but the VSE was rebooted before applying it, the UI would only communicate there was an update to download, not that it was already downloaded and ready to be applied. Known Issues •StrataSync Technician IDs with leading space “ “ character(s) are not recognized. For example: “ 1234…” will not be recognized. A “Failed to connect. Check network connection and account ID” message will be displayed.

Bug fixes.

Release 1.0

Changes: MER Failure Thresholds set Fixed occasional 0 dB MER readings. Auto-Template now detects 6.777 MHz MSPS channels RapidScan channel search results will now show the service number in the search results (abbreviated "sn"). QAM unlock detected during Logical Channel Plan and UCD capture NoiseTrak and the JDSU 3-bar menu will now be accessible if the user is viewing the application in Japanese. Fixed an issue where RapidScan Channel Details wouldn't be displayed in a saved screenshot. Improved the Settings screen so that it won't cause as many disconnects if it's accessed while on a Downstream Single Channel screen. Added an alert to the Wifi configuration screen if the VSE failed to authenticate with a Wifi access point. HyperSpectrum now shows "Attenuation" rather than "Input Level". The change was made because the value shown is close to what effective attenuation is being applied, rather than what input level it's adjusting to. Fixed several Wifi configuration screen issues where it could get out of sync with the VSE and display the wrong state. The Settings screen will now indicate if Wifi is connecting to an AP. The Settings screen will now show the IP address of the VSE when successfully connected over Wifi. If the VSE fails to connect to a Wifi access point, it will now indicate that it is not connected on the Settings screen. Fixed an issue where a delta marker would be one update behind its parent marker if it was to the left of it on the screen. Previously the Logical Channel Plan view screen could get out of sorts if search text was entered and the user switched back to sorting. This issue should be fixed. Added an alert to the user if we believe the first Known Issue below is happening. If the user selects OK, the application will close. Otherwise the user can select cancel and keep using the application while not connected. Upgrade screen should no longer allow exiting while applying an upgrade. The VSE will automatically attempt a sync after applying the upgrade in order to notify StrataSync that the upgrade was successful. Please allow another minute or 2 on the netwrok after the VSE reboots for it accomplish this, so we can track versions more easily. Fixed a few cases where Downstream wasn't running automatically as we intended. Randomized MER reading time. Auto-reference on the screen should behave better when a value less than 10 dB/Div is selected. Analog audio levels are now present in the Downstream Results view. Improved the MER graph collapsed state tracking so that it will appear when needed (if desired) and disappear when unnecessary. Fixed a cosmetic issue around the RapidScan MER graph grab-button not always being centered. Known issues: If the application is unable to connect via USB, force quit the application (press the home key twice, swipe upward on the application) and re-launch it from the home screen. Battery capacity can vary when below 10% capacity. Annex A 7 MHz channels show QAM ingress when there is a lower adjacent analog video carrier

Handle the Apple USB disconnect gracefully More translation work Many small bug fixes
