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.

R13

Please read before applying this software

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

Previously only PTP was supported on the new 10G hardware. This release now adds support for NTP including IPv6 and DHCP. NTP Client or NTP monitor mode can be selected from the Mode page as shown below.

Note: IPv6 and DHCP are only available on units with serial number 400XXX or units that have been upgraded to 10G.

  • 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.


R11.0.1

Defect fix

  • Packet module does not send IGMP messages for multicast routing.


R11

Features

  • 10GbE functionality

Defect Fixes

  • [SEN-1085] Ethernet Gateway Ping button is enabled when DHCP is enabled.

  • [SEN-1151] Sentinel doesn't reach 128 packets per second for Delay Request rate.

  • [SEN-1726] Configuring Sentinel from Electrical to optical ethernet results in no RevPDV being recorded.

  • [SEN-1781] Apply button will only change IP address / Mask / Gateway setting on the first press.

  • [SEN-1796] Protocol check does not detect Delay Response if multiple PTP multicast flows are present.

  • [SEN-1803] Moving from GNSS settings page with invalid value on antenna delay causes crash.


R10

Features

  • This release offers a software and hardware feature enhancement on Sentinel. New options are associated with this enhancement (Option 700 or 710), providing Time Error (TE) accuracy measurements on LTE signals Over The Air (OTA), by way of a measurement module which can be fitted to one of three module slots on the Sentinel platform.

  • The software incorporates the following optioned features:

  • ‘Over The Air’ Time-Error

  • LTE Time Error measurement solution.

  • TE measurements for ITU-T G.8271.1/2 network requirement of 1.5us at the air interface.

  • Frequency (TIE) measurements for ITU-T G.8261.1 network requirement of 50ppb at the air interface.

  • Small Cell (Macro/Femto/Pico) Time Error measurements.

  • FDD and TDD LTE operating modes, covering frequency bands up to 3.7GHz.

Please contact your local Calnex sales representative for more information on measuring Synchronisation ‘Over The Air’.


R9.1.1

Defect Fix

  • Loss of GNSS Module Configuration When Re-booting:

If the antenna delay was set to a non-zero value then the GNSS module would not apply that offset if Sentinel was re-booted, the quality of the 1PPS output from the module to the internal Rb could be degraded and the site survey may not complete. Additionally, if the module was capable of supporting multi-GNSS constellations the saved setting would not be applied and the module would be configured to use GPS and GLONASS constellations. Pressing the Reset Module button had no effect.


R9.1

This release offers software only feature enhancements on Sentinel. No new options are associated with these enhancements.

Features

  • The software has added the following feature and change to Sentinel:

  • NTP support for 2 Way Time Error measurement.

Defect Fixes

The following known issues have also been resolved:

  • GPS module may report incorrect satellite status and number of satellites it is locked to.

  • When a measurement is re-loaded the measurement.summary.txt file is re-written.

  • Packet capture incorrectly names files saved for channel E.

  • Measurement.summary.txt file does not show max / min results for 2WayTE.

  • GM Identity saved in measurement files is incorrect.


R9

This release offers software only feature enhancements on Sentinel. No new options are associated with these enhancements.

Features

The software has added the following feature and change to Sentinel:

  • Enhanced 1PPS measurement.

  • 2Way TE measurement now uses a 0.1Hz filter.


R8.1.2

Defect Fix

  • Fixes an issue with the number of satellites indicated.


R8.1

Features

The software has added the following feature and change to Sentinel:

  • Powering off Sentinel has been simplified by using a single pop-up to control all power down options.

 Defect Fixes

The following known issues have also been resolved:

  • SyncE wander generation amplitude and frequency accuracy has been improved for frequencies above 1Hz.

  • In monitor mode the correction field was incorrectly used in calculating forward and reverse PDV measurements. The correct formulas are now implemented.

  • The PTP statistics csv file had all fields set to 0. The statistics are now saved correctly.

  • False battery fault indications have been resolved.

  • The 1PPS icon turns red during measurement incorrectly indicating loss of External 1PPS input.


R8.0.1

Defect Fixes

  • Wander generator amplitudes inaccurate for wander above 1Hz.

  • Wander generator doesn't work for low frequencies and low amplitudes.


R8

This release offers software only feature enhancements on Sentinel. No new options are associated with these enhancements.

 Features

The software has added the following features and changes to Sentinel:

  • Ease of setup.

    • 128 packets/second can now be transmitted.

  • Lock button: The lock button will not unlock when the measurement complete pop-up box is displayed. A possible workaround for this is to VNC to Sentinel and press OK to clear this pop-up box, then the lock button will unlock.

    • Pop up box can be acknowledged then Sentinel lock button used.

  • An issue has been observed when entering certain values in the Antenna Delay field of the GPS settings. Some values will have no effect on the measurement result. If this is the case, then setting the antenna delay 1ns above the desired value will work as expected.

    • Root cause identified and all values now work

  • Remote access password could not be set in R7.x o Root cause identified and can now be set.
