  • Recover deleted test results. If you saved results with Version 1.3 then inadvertently deleted results using your DTX CableAnalyzer, power down the unit, hold down keys F1 and EXIT, power up the DTX and let go of the keys once it has finished playing a tune. This function works for both the Internal Memory and any MMCs inserted using Version 1.3 code. It will not work if you formatted the MMC or have older code. For help in recovering results from formatted MMCs, please e-mail
  • Add setup item to force HDTDR and HDTDX to run with every test. You can find this in Tab 2 of SETUP. It will add approximately 6 seconds to each Autotest. HDTDX and HDTDR normally run on marginal passes or failures only. Since the DTX is so accurate, marginal passes could be with margins as low as 0.3 dB. If the margin is only 1.0 dB, HDTDX will not run and we will need to ask you to run HDTDX in Single Test to help you diagnose the cause of the low margin. Turning this feature on will help us to help you diagnose low margins better.
  • Extended the number of Cable IDs in the preset list from 253 to 2000.
  • Disable shield testing when selecting FTP or SSTP, requested by customers where the channel test has a UTP user cord. The status is shown on the main screen of the DTX so you know whether the shield is being tested or not.
  •  Warning message at end of Autotest for negative fiber loss results. If there is a negative loss of more than -0.09 dB, a warning will be given.
  • Loopback fiber module selftest added.
  • Rollover and Crossover added to Outlet Configuration.
  • Disable Wire Map Checking for Mid-span DTE Testing. Some Mid-span DTE devices do not pass through DC signals making it impossible for the DTX to complete a DC Wire Map measurement. Creating a custom test limit now lets you disable Wire Map checking.
  • Factory Clean you can restore your DTX to its original factory defaults. Rotate the dial to SPECIAL FUNCTIONS and select Self Test. Connector the main and remote units together, power on the remote unit. Press F3. Several warnings will be given. This will ERASE ALL SETTINGS and TEST RESULTS.

  3.     Bug fixes (Non of these affect the outcome of your test results) 

  • Wire Map Short circuit graphics misaligned.
  • Coax 10BASE-2, 10BASE-5 Prop Delay not present In Single Test.

  • Top Summary Screen shows wrong margin for failing IL.
  • Return loss margin reported within the 3db rule range.

Changes from Version 1.0 to 1.1 (Januray 2005)

  1.    New features

  • Due to improvements in data processing methods, the following test times are now applicable: (it really is 9 secs for Cat 6)

    DTX CableAnalyzer Test Standards
    The speed of the NEXT, Return Loss measurements have not been altered, only the calculation process. Speeding up the NEXT, Return Loss measurements reduces the noise floor and dynamic range of the instrument which in turn compromises accuracy. 


  • New Autotest Results Screen. With many cabling vendors guaranteeing margins of performance, the DTX will now report the worst case margin for each parameter at the end of the Autotest. These values are reported in parenthesis:
    Autotest Results 


  • Standards Database Updated
    The 10GBASE-T entries have been changed to reflect the new DRAFT 500 MHz requirement from the IEEE.
    Standards Database Updated Screen
    The 10GBASE-T CH Cl E 0-55m entry supports 10GBASE-T over existing category 6 / class E installations to 55 m. 10GBASE-T CH Cl E 55-100 m is for new UTP cabling systems designed specifically to eliminate Alien Crosstalk, the coupling of noise from one cable to the other. It also supports existing category 6 shielded cabling systems where Alien Crosstalk is not considered such as issue due to the shielding of the cable and connectors. In addition to this, you will find new entries in the TIA Folder:
    TIA Cat 3 Channel         TIA Cat 5 BL (TSB-95)
    TIA TSB-155 CH dr 1.1a is a channel measurement designed to verify the performance of an existing category 6 cabling system for 10GBASE-T operation. The same is for TIA TSB-155 PL dr 1.1a.
    TIA AugCat6 CH dr 2.0 is a channel measurement designed to certify new category 6 cabling systems designed to support 10GBASE-T over the full distance of 100 meters. The same is also for TIA AugCat6 PL dr 2.0, except this is a permanent link test where the distance is 90 meters.


  • TSB-95 has been added to support previous / existing category 5 installations. This is an obsolete standard, hence the BL (Basic Link) nomenclature.


  • VCSEL Fiber Option (DTX-GFM)
    For those who prefer to test with a VCSEL, there is now a VCSEL 850 nm / FP Laser 1310 nm option:
    DTX-GFM VCSEL Fiber Option
    This is for the verification of 1000BASESX or LX over multimode cable. If you require certification, you should continue to use your existing DTX-MFM module since the cabling standards specify the use of a category 1 light source.


  • Fiber Optic Meter
    Since we were unable to make the DSP-FOM work with the DTX, there is now a new power meter only module:
    Fiber Optic Meter
    For those wishing to carry out basic fiber testing, this is ideal. It can be used with an existing 850 nm, 1300 nm, 1310 nm or 1550 nm light source.


  • Battery Conditioner
    If your battery does not appear to last as long as it should or used to, it is probably dues to the internal gas gauge in the Li-ION battery drifting. To reset it, rotate the dial to SPECIAL FUNCTIONS and select Battery Status.
    Battery Status Screen
    Connect the testers together, plug in the power supplies and press the F1 Key. It is recommended to do this every six months. This will ensure maximum battery performance.


  • Coax Test
    Not just a coax test as with previous testers. This coax test includes insertion loss. The optional modules (DTX-CH003) are placed on the main and remote unit. Insertion Loss measurements can be made up to 350 meters.
    Coax Test - Insertion Loss
    The presentation on the adapter is F-Type with F-Type to BNC Adapters supplied to allow the testing of CCTV and 10BASE-2.


  • Patch Cord Test
    Just as with the DSP-4x00, you can now certify patch cords with the optional DTX-PCU-6S.
    Patch Cord Test 


  • Siemon TERA Adapters
    Only Fluke Networks DTX-1800 is approved to test the Siemon TERA Cabling system. Both Channel and Permanent Link Adapters are available.
    Siemon TERA Adapters 


  • Multiple Operator / Site Names. Just as with the DSP-4x00, you can now have up to 20 operator and site names in the DTX CableAnalyzer.


  • Automatic Module Detection.If only the fiber module is inserted, you will only get the fiber options menu. This is true for the optional coax module as well.


  • Custom Cable Type. If you have a vendor that is not in the cable library, you can create your own. Up to 9 custom cable types can be created.


  • Custom Test Limit Setup. You can now create your own cable tests based in existing tests. It is possible to remove certain test parameters. However, the standards name is prefixed and suffixed with an asterisk to indicate a custom cable test. This is true for fiber and copper tests but not for coax tests at this time.
    Custom Cable Test Setup 


  • Custom Outlet Configuration


  • Extended Frequency Option
    Although the category 5e standard stops at 100 MHz, we have received numerous requests for the measurement to continue to 350 MHz but keep the limit line standards compliant to 100 MHz. This is now possible by rotating the dial to SETUP and selecting Instrument Settings. Under Store Plot Data, you will see the following 3 options:
    Extended Frequency Option Screen
    No will mean that no plot data is stored. Standard will store plot data and Extended will store plot data to 350 MHz. This is also true if category 6 is selected. When class F and Extended are selected, the test will run to 900 MHz.


  • Scanning Function
    As with previous testers from Fluke Networks, the user has the ability to continuously measure a link for the parameters Wire Map and Resistance.
    Scanning Function 


  • HDTDX @ HDTDR Cursor Improved
    HDTDR Cursor Improved Screen 


  • HDTDX @ HTDR 4x Magnification. Using the F2 Key, you can now zoom on the vertical axis.


  • Permanent Link Field Calibration. Using the existing DSP-PLCAL Module and the new LinkWare 2.3, the DTX-PLA001 can now be calibrated, just as with the DSP-4x00 DSP-LIA101.


  • UL Verified Accuracy Bands Implemented. The region deemed as marginal has changed slightly to reflect the independently verified accuracy of the DTX by UL (Underwriters Laboratories). 


  • New Languages. Russian has now been added:
    New Languages Setup Screen


  • LinkWare Stats can now be exported to PDF. If you have LinkWare Stats installed, updating to LinkWare 2.3 will automatically install LinkWare Stats 1.2.




2.   Minor Bug Fixes 

  • 3 dB and 4 dB rule enabled in single test.
  • DTX does not reset during fault diagnostics if the link is 30 meters and fails the autotest now.
  • Stale test limits in Last Used list are deleted when software is updated.
  • Retain most recent test on power down.
  • SYSTIMAX 3071E in Cable Library had incorrect NVP. It has been changed to 69% from 68%.
