DAS-1600 Series Power Amplifier

Post by jlee_kaz » September 6th, 2012, 11:25 am

I have a fairly old power amplifier, and I am having a hard time figuring out what the exact model is. It has "DWG1439" on the front, but I can't find another serial numbers on it elsewhere.
The only clues I have are that I have a bunch of floppy disks that is software for the 'DAS-1600 series' and 'ASO WIn 95 32-bit' driver information that dates back to 1995. Furthermore, it is connected to a physical port on the back of the computer that was running Windows 98 (computer is pretty dead now). There is a Borland C++ script that was used on that computer in order to control the power range and cycling.

I'm trying to figure out how/if I can use this power amplifier on another newer computer, along with the C++ script. Are there newer cables that I can use to connect it to the computer? I understand that new computers probably don't have that kind of port. Also, is there any other way to install driver and software for this power amplifier? I don't have any computers with floppy drives.

Here is a link to the DAs-1600 series drivers on the KI web site.
Maybe that will help.

Also here is a link to all the information about the DAS-1600 series that Keithley has to offer on this obsolete unit.

From the FAQ, it appears that the ISA boards for the DAS-1600 Series cannot be used for any of the newer computers. However, I am asking about connecting the power amplifier (DWG-1439) unit.
Do you know of any other way to connect a Windows 7 Prof computer to the power amplifier in order to make it run the C++ program, or do I need to purchase a new power supply?

Looks like a new supply would be the way to go.

What model would be similar to the one that I am using? From what I understand, the power supply was used to operate a Langmuir probe that measured plasma density, and the C++ code controlled the voltage sweep setting and the cycling time.

Basically, the probe went from a low potential to a high potential for many cycles. During the sweep, current would be collected from electrons from the plasma, and it would spit out the current collected vs. voltage.

Sorry. Keithley has no power amplifiers on a DAQ card.
If this is what you need, the I would recommend "Data Translation". They may have something for you.

Ok, I think I'm starting to understand what is going on. I did some more digging, and I believe that the power amplifier is actually home built by our electronics department. However, that department closed down a while back.

Does Keithley have any USB compatible DAQ that functions similar to the obsolete DAS-1600? Or do most DAQ devices perform in similar manners? Basically, I am wondering if there are any hardware incompatibilities in general.

Take a look at the KUSB-3100 series.
Here is the link.

The connector for my power amplifier to the DAS-1600 is a 37 pin D connector. Is this compatible with all of the KUSB-3100 series?

A single USB cable, shipped with each KUSB-
3100, -3102, -3108, and -3160 module, provides
both power and signal connections from your
PC. No external power supply or battery is
required. The KUSB-3116 includes a USB cable
and +5V 2A power supply and power cable.
Signal connections are made directly to each
module using either screw terminals, BNC
connectors, or 37-pin D-type connectors located
on the module itself. The KUSB-3102 and -3108
provide removable screw terminal blocks. Pin
assignments are clearly marked on the module
labels for quick setup.
