Re: 6221 drift at zero current

Hello, The link below is the data sheet for 6221. Sourcing 0 current is not necessarily 0. Please, look at the error considerations in terms of specs at a given range. Also, I am assuming that you are accounting connection errors and you are using a precision resistor. http://www.keithley.com/suppor...

Re: Measurement Speed through GPIB

Your consideration of loading a script into the box is the way to go to speed up your measurement. Below is the link of some sample programs that might be useful for you.

Re: Scanning multiple channels using labview programming

Hello,
With 3730, you can make multiple crosspoints to make your source and measure. See linked below;

(Go to 3730 information/diagram).

If you are only using the DMM as your stimulus/measurements, then you can only make one crosspoints at a time.

Re: Need advice on a new buy (plug in card for 3706A)

It is my assumption that your measurements uses the built-in DMM of the 3706 to measure AC/DC voltage. On the other hand, I am not clear about the real time measurments of your 15 sensors. If you are using the DMM, you will scan the DUTs one at a time from DUT #1 -> DUT #15. If this is what you inte...

Re: low current measurement on 6430

Hello, In the manual Section 5, Source - Measure Concepts (Figure 5-12 to Figure 5-14), the measurement and connection is discussed. In our low level measurement handbook, the different sources of error for High Impedance is discussed in detail. http://www.keithley.com/support/keidoc_searchresult?ke...

Re: How to use one Keithley 2602 and another Keithley 2400

Once your timing from the above answer is to your liking, you can enhance your measurement by doing below possibility;

Use a trigger - (Digital I/O) output of the 2600 to the 2400 input at a given instance.

Re: How to use one Keithley 2602 and another Keithley 2400

Based on your information, it occurs to me that your measurement/sense timing (2400) is not in sync with your sources timing (2602). Have you tried using a scope to see if everything lines up? This way, you will know how everything looks with your sources and measure instrumentation.
