R20.1

Features

• Support for 25G and 100G rate options
  Sentinel can now be configured to make 25G and/or 100G measurements (Time Error and SyncE) on up to two channels where supporting packet module extension card is fitted and the appropriate license is purchased.

• Simplified PTP
  Defined by the Open Compute Project (OCP), simplified PTP exchanges a reduced set of packets and simplifies sync management in certain data center applications.

• Improvements to TIE modes
  Several enhancements have been made to the TE mode menu on the measurement tab.

  • Default mode changed to TIE + 1pps TE
    As it is the most used clock measurement mode, TIE + 1pps TE mode is now the default option for TIE Mode. In this mode, the Time Error (TE) of any 1PPS signals presented to the clock card are displayed on the TE display. The time interval error (TIE) of any other clock signals is displayed on the TIE display.

  • Removal of TE
    The TE option is no longer required and has been removed.

  • TIE + 1PPS Alignment
    The ‘TIE + 1PPS TE’ mode follows the ITU standard. According to the ITU standard, if the 1PPS signal being tested has an extra or missing pulse there will be a 1s offset in the measurement. Alignment mode ignores extra or missing pulses and compares the reference to the edge of the nearest pulse of the input signal if present.

• Protection from flashing malicious firmware
  Sentinel checks the firmware signature prior to updating to avoid the loading of malicious firmware.
  As consequence of this enhancement, once this version of software is loaded onto the instrument, it will not be possible to downgrade to any earlier version of the firmware.

• Improved management of clock channels
  Enhancements have been made to improve the usability of the available measurement resources in the instrument. SyncE measurements can now be turned off from the mode page when not required. This frees a measurement channel for 1pps TE measurements when the internal reference is used.

• Support for G.811 PRC Wander Generator Masks
  MTIE and TDEV masks for G.811 Primary Reference Clock wander generation are available under the masks tab.

• TLS 1.3 Support
  TLS 1.3 is now supported on API for HTTPS connections

• SSH
  As an additional security measure, SSH is disabled by default.

Resolved Issues

Monitor mode is now able to make measurements longer than 4 days.

R16.0.2

Features

• Battery Enhancements
  This release enables the use of Option 631 Battery Powered Operation. Instruments with this software release and Option 631 Battery Powered Operation fitted will benefit from the below features:

  • Transport Mode - maintains phase accuracy of Sentinel’s disciplined internal Rb clock when mains power is removed, allowing for accurate reference when the instrument is transported to site.

  • UPS - should external power to Sentinel be interrupted, the internal battery will act as an uninterruptible power supply and allow Sentinel to continue to be used until power is restored or full discharge of the battery.

  • Battery powered OTA measurement - allows Sentinel to operate without external power, maintaining accuracy of the Rb clock and enabling measurements to be made.

Defect Fixes

• [SEN-2843] Clock channel triggers always on negative slope despite Slope setting. See Sentinel: Clock Channel Triggers Always on Negative Slope (Resolved) for more details.

• [SEN-2992] 1pps TE channels not plotting in TIE+1pps TE mode, unless SyncE is enabled.

• [SEN-3070] TE offset on 100BaseFX interface. See Sentinel: 100M Optical Interface Offset (Resolved) for more details.

• [SEN-3194] “Enable OTA Low Power Mode” shows on Mode page when OTA Low Power Mode is enabled.

• [SEN-3376] Battery not recognised for small subset of Sentinels.

R15.1

Features

• OTA-NR Cell Scan
  This release adds cell scan capability for OTA-NR, similar to the existing cell scan feature for OTA-LTE. For full details please refer to the Sentinel User Manual.

R15

Features

• Added Metrics and Masks
  A range of metrics and masks have been added to Sentinel as summarised in the table below:

Defect Fixes

• [SEN-2514] During a 5G OTA measurement, if the signal loses lock and then regains lock the graph doesn’t update.

• [SEN-2476] During an OTA measurement, the widget was indicating the opposite sign to the graph.

R13

Features

• HTTP(S) Interface
  An HTTP(S) interface has now been added to Sentinel allowing a basic remote control functionality. For full details please refer to the Sentinel User Manual.

• Continuous Measurements
  An option has now been added to the measurement settings page to allow the user to select continuous measurements. This means that Sentinel will continue to make a measurement on a rolling 24 hr basis.

• IPv6 on the Management Port
  There is now the ability to use IPv6 addresses on the management port for Sentinel.

• Disable SyncE
  SyncE can now be disabled independently of PTP/NTP measurements. This feature is available via the mode page.

• Disable Metrics
  If you don’t want to run any metrics or masks you can disable this on the measurement settings page.

R12

Features

• NTP functionality is now supported on the 10G hardware

• Using the CAT to review results

  • The Calnex Analysis Tool (CAT), versions 24 and later must be used to examine the results from the new module, channels 1 and 2.

  • Copy the measurement files of interest from the Sentinel to a PC which has CAT installed. On opening these files within CAT, you will be able to select the TIE and PDV metrics and view the results.
