Tektronix TDS700A Field adjust software- help needed

[Jay_Diddy_B]

Hi group,

I am interested in the possibility of upgrading my TDS744A to either a TDS754A or TD784A as described in this thread.

I have one 744A and two 754A.

https://www.eevblog.com/forum/testgear/tek-tds-3054b-vs-tds-744a/

In order to do this I would like have a functional version of the Tektronix adjustment software.


 So far I have taken the following steps:



1) Found an old PC with an ISA bus slot.

2) Run FDISK

3) Format C drive

4) Installed DOS 6.22

5) Installed the drivers for NI GPIB II/IIA card.

6) Set the card for PC II operation

7) Card is set for IRQ 7

DMA Channel 1

9) Card address is set to 0x2B8


I can test the card with the Utility supplied by NI and the card responds.


I then installed the Tektronix TDS700A software.


The Tektronix software will run. If I connect a TDS754A ( I have tried two), If I go the Utility -> I/O menu and set the GPIB address to 1 talk/listen.


When I run the software I get the following error message:


DUT I/O ERROR -> NO DUT FOUND ON THE BUS


Any ideas what I am doing wrong?



Thanks for your help.

Hi Group,

I posted the question on the Tektronix Yahoo groups forum. I got some guidance from one of the members there.
Here are the answers:

Card: PC2A
 Base I/O: 02E1
 No DMA
 IRQ 7
 The set commands in the created bat file say: GPIB0=PC2A 0 7 0 and GPIB1=PC2A 0 7 0

I installed a NI GPIB PC II/IIA card in my computer with the DIP switches set like this:



Note: The DMA jumpers are open, this is the configuration for no DMA.


I edited the ADJ700.BAT file like this so that GPIB0 and GPIB1 are configured to access the GPIB card.




I removed the NI drivers from CONFIG.SYS. The Tektronix software does not need the drivers.

I can now run the Tektronix Field adjust software.

The computer I am using is a Compaq Deskpro 2000 (1996 - 1997 Vintage)

The key requirement is that the PC has at least one ISA slot for NI GPIB PCII/IIA board.

Running Windows 98 second edition

The RAM is 64 MB

The CPU is marked A80502133 which is 133 MHz Pentium (1995 Vintage)

This is about the same vintage as the scope.

Thanks for the computer info.
But, brobably I will be wrong, but I think the software have to be start from a pure dos machine.
Thanks any way.

Hi,

The software will run in a DOS window on this machine.

I know but i think it won't work as far as I know. Look in the tek forum for more info.

Here are a couple of photographs showing the software working in a DOS window on Windows 98se machine:



The second one shows the software is communicating with the scope over GPIB:

Talking about old school...   
I think I have one of those GPIB cards somewhere but never got round to actually using it for calibrating a TDS700 series scope. You need an RF generator capable of quite high output signal levels.
