TDS Performance Verification Softwares

 

These softwares do a Performance Verification of various types of TDS scopes, all according to the Service Manuals.

Most steps are done exactly as stated in the manual although some have been enhanced to do a more thorough testing. In a few cases the procedure

has been altered to match the specs rather than the procedure in the manual due to obvious errors in the manual. For a semi automated sequence the

programs supports SG5030 or R&S SME03 for SG's and FLUKE 510x for DC Calibrator. With semi automated I mean that all settings are done via

GPIB but the user is prompted to do or move connections to the CH inputs. There is also a full auto mode which does all signal switching and uses

predetermined compensation values for frequency (B/W) and cable lengths (Channel Skew). This however works only on my own setup of instruments

and it is highly unlikely that a setup exactly like it exists anywhere in the world. With no GPIB instruments it could also be run manually, i.e. the user is

prompted for settings of the test instruments. The TDS,  however, must be connected to GPIB or the program won't start. The program selects mode

depending on what instruments it finds on the bus. The GPIB address of the scopes is not important as long as it is not 0. Should there be more than

one TDS of the right type on the bus the one with lowest address is selected. Additional features are creating, saving and printing result data files,

built in GPIB Communicator and TDS Error Log Viewer. The TDS 200, TDS 1000/2000 and TDS 3000 versions contain routines to do a full adjustment

of the scope and also to change the type of scope e.g. you could change a TD S210 to TDS 220 or a TDS 3014 to TDS 3054 to increrase the bandwidth.

On the TDS 200 and TDS 1000/2000 a change of type requires a full adjustment to be done for the new type to be saved.  This change-of-type routine

is initially locked in the software but can be unlocked for a small fee, just follow the insructions given in the program.

 

Below is a typical screen shot. They all look the same.

 

 

The > before PASS occurs when the result is more than 70% of the given limit and off course should the result be outside the limit FAIL will show.

TDS3000 v2.1.1   New June 10, 2016

 

Changes from 2.1.0 to 2.1.1

 

 Bugfix:

  All 300 MHz scopes failed BW test. Thanks Bob H for letting me know.

 

 Issues with this version:

  Supported scopes for Performance Verification are all TDS 3000 no letter, B and C except TDS 3064B.

  Supported scopes for Adjustment are all TDS3000 no letter and B except TDS 3064B.   

  Supported scopes for Change Type are all TDS3000 no letter and B except TDS 3064B.

  Reading the Error Log or Change Type does not work on scopes with F/W 3.41. That Error Log doesn't work has been confirmed by Tek in a slightly cryptic reply.

  A solution if you want to change type and already have 3.41 is to temporarily load v3.39 which works.   Download 3.39 here.   Latest version could be found on Tek's website.

 

Changes from 2.0.0 to 2.1.0

 

 Bugfixes:

  Incorrect GPIB command in Adjustment procedure (Auto mode only).

  Incorrect amplitude settings for Trigger test on B and C models.

  Incorrect Limit for Sample Rate check on C models.

  Test Aborted message was not shown in Trig Test when Exit Test was selected.

 

 Changes:

   Adjustment procedure changed to work with and verified for 4 ch B-models.

   Change Type procedure and messages slightly changed.

   Support for TDS 3064B added on PV and adjust but not Change Type.

   Ext Trig Connection message at start of Auto mode deleted.

   50 ohm terminators reminder message when starting Gain test in Auto mode deleted.

   Handling of various SG/TDS combinations changed so two generators could be used for BW and Trig tests on some TDS's.

 

 2.0.0

  This is the first published version.

  Please, note that this could be considered a beta version since I have only been able to test it fully on a TDS 3014 changed to TDS 3054.

  So there may still be some bugs or issues I haven't detected yet. Use the email link at the bottom of this page to report whatever you find.

TDS400 v2.2.4   New April 25, 2016

 

Changes from 2.2.3 to 2.2.4

 

 Bugfixes:

   Bandwidth check didn't work on A-models due to the same problem seen in the 500-version some time ago, i.e. the on screen measurements were incorrect on CH2-CH4 when those

     and Immediate Measurements (not shown on screen) didn't have the same source channel. This must be a F/W bug in the scope. Tested scope was a 420A with F/W 1.0.2.

   Long-term sample rate and delay time check didn't work properly on A-models (could not blame the scope there).

 

Changes from 2.2.2 to 2.2.3

 

 Changes: 

  Main form caption slightly changed.

  New version of the embedded GPIB Communicator program.

  Show Module versions moved to View Menu (from Utilities Menu).

TDS500/600/700 v1.1.2  New July 30, 2015

 

Changes from 1.1.1 to 1.1.2

 

 Changes:

  Main form caption slightly changed.

  Show Module versions moved to View Menu (from Utilities Menu).

  Show Module versions appearance slightly changed.

  Show Test Parameters moved to View Menu (from Utilities Menu).

  Menu Utilities/GPIB Communication renamed to GPIB Communicator.

 

Changes from 1.1.0 to 1.1.1

 

 Bugfixes:

  Still problems with Analog Bandwidth check on some scopes. The scope will randomly send incorrect P-P values causing the test to fail. The problem always occured on CH2 to CH4.

    It appears that if, although not used, the Immediate measurement (not shown on screen) had a different source channel than the P-P measurement shown on the screen this could

    happen but only on some scopes. A TDS784A would fail while a TDS544A wouldn't. Firmware bug in the scope ??

 Timeout for SPC could somtimes be to short (300s) causing a Time Out message. It was changed to 1000s (16.67 minutes) which is the only available as next higher..

 

 Change:

  New version of the embedded GPIB Communicator program.

 

Changes from 1.0.1 to 1.1.0

 

 Bugfixes:

  A timing issue would cause Analog Bandwidth check to fail. Thanks to Bob H for letting me know.

  No warning and no change of SG if an SG5030 was used on a 1GHz scope resulting in the system trying to set the SG5030 to frequencies higher than 550 MHz.

  When in Full Auto mode (only applicable to my own Cal System) the SetSG command didn't use the system comp values in BW check if a R&S SME03 was used for SG.

 

 Change:

  The link in About to check for updates changed from the index page to the this page.

 

Changes from 1.0.0 to 1.0.1

 

 Bugfix:

  Runtime Error when using illegal characters in Logfile name.

 

 1.0.0  This is the first published version.

  Since it supports a large range of instruments I have not been able to test and verify every configuration.

  Hopefully there won't be many errors but I would like to know of any bugs or preferred changes.

  Use the link below or the one from the About window of the program

TDS1000/2000 v1.1.1   New July 30, 2015

 

Changes from 1.1.0 to 1.1.1

 

 Changes:

  Main form caption slightly changed.

  New version of the embedded GPIB Communicator program.

  Show Module versions moved to View Menu (from Utilities Menu).

  Show Module versions appearance slightly changed.

  Menu Utilities/GPIB Communication renamed to GPIB Communicator.

 

 Changes from 1.0.0 to 1.1.0

 

 Bugfixes:

  Runtime Error when using illegal characters in Logfile name.

  Incorrect settings for External Trig test.

 

 Changes:

  Contrast adjustment for color scopes (2k) enabled after function has been verified to work.

  Message saying that a full adjustment is needed to save Contrast adjustments removed since this is not the case for TDS1k/2k.

 

 1.0.0

  This is the first published version and it supports also B and C models.

  The Change Scope Type function is only enabled for non letter scopes in this version since I don't have any letter scope to verify it with.

  For the same reason the Adjust Contrast is only enabled for monochrome scopes.

  If someone with a letter scope is willing to test the function let me know and can send a version with all functions enabled.

_________________________________________________________

 

Be sure to uninstall any previuos version before installing this one or extract the *.exe file from the *.CAB file and replace your current file.

 

You must have a NI GPIB card with the correct drivers installed.  Find  and download National Instruments GPIB card drivers here.

 

It is expected to work on any PC/win OS (not 3.1) with a correctly installed and working NI card/adapter.
