Re: Difficulty connecting 2812A to 6221

For just the 6221 and 2182A without PC, do the features such as delta mode operate without error? Just push the Delta mode button. Any errors? If no errors, then the config of the communication between the two instruments is properly working. You need the null modem and trigger cable. Also, RS-232 s...

Re: A.C. Impedance measurements with Labview & Keithley 2400

A SourceMeter such as model 2400 is not suitable for what you describe. Even when SourceMeter is used for AC impedance, two are required. One to apply the voltage sine wave; and one to measure the current in time sync. This can give you the Z and phase shift. Even so, the freq of the resulting sine ...

Re: Two SMU based Photodiode measurnment

Hello, For the two SMU, have one apply a 0V bias and measure current while second SMU applies non-zero bias and also measures current. The currents from each SMU should be equal (within specs for the ranges) but opposite in sign. For the timing in the test, since both SMU are simple bias, you can us...

Re: LabTracer software: Visa Open Error code: 1073807265

LabTracer software is quite old and often has problems in the security models of newer versions of Windows such as Windows 10.

For use with your 2400 SourceMeter, I suggest you give KickStart a try"

Re: Problem with reading data from keithley 6485

What you describe is very strange and not expected behavior. Is there perhaps some sort of error message? You can certainly change settings and still have it respond to new read commands. Can you capture a trace file from NI IOTrace? This might let us better understand. BTW: is this GPIB or RS-232?

Re: 4200-SCS remoting probles via ethernet

When using Ethernet to connect to the KXCI command parser, the SP command is used to obtain the Serial Poll byte information. The serial poll gives you important information such as when is the measurement done. The DO command is correct for getting the data out. But measurement needs to be complete...

LabVIEW is just one choice. Consider Python or other open source tool for budget solution. There is quite ...

Re: Does Keithley 2450 can realize the electrochemical test function?

The model 2450-EC contains: the 2450, the TSP scripts for Electro-Chemistry and some cables that may be helpful to connect to your electrodes.

If you already have the 2450 SourceMeter, inquire with your local sales office for the EC-UPGRADE to obtain the TSP scripts and the cables.

Re: Applications of 7072 switch card

One 7072 in slot 1; one in slot 4; and 707 configured as two 3-slot matrix. This creates analog pathway isolation between the two 7072 cards. To use the two 2636 independently, you still have to close relays on slot 1 or 4. And then command the corresponding SMU to force and measure. What you can’t ...

The compiler install instructions also indicate that an internet connection is needed. If no connection, that will account for the missing items during the Microsoft Visual Studio compiler install and it does interfere with KULT operation. You mention this is a 4200A. Any chance you have Windows 10 ...

Re: Applications of 7072 switch card

When 7072 is installed in the 707 mainframe, rows C through F are expanded to adjacent cards on backplane relays. However, 707 slots 1 through 3 can be separated from slots 4 through 6. Check pg 2-20 and 2-21 of 7072 manual. If 707 is properly configured, place one 7072 card in slot1 and one card in...

Re: Arb pulse generation using GPIB commands

Hi,

To have the 4200 respond to gpib commands, it will need to be in KXCI mode for command parsing.

KXCI has UL command that will allow you to execute compiled user libraries (that you write in KULT). Your SegArb mode operation will need encapsulated in a KULT routine.

Re: 2461 limiting voltage to 35.7V

rogerio.hein: You have a different issue than what was reported for the 2461. The 2400 does not have true interlock. Just an optional output enable. In contrast to 2461 and interlock, the 2400 does not restrict the voltage when optional OE not used. So why are you stuck at -40? What are you connecte...

Re: Odd Errors ACS, TSB with 2612A

That is odd. You seem to have a couple different things going on. If the script used to work, but after power cycle does not, it implies to me that the script that was in memory but the power cycle removes it. The complaints about a global value being nil is typical symptom for that situation and it...

Re: KickStart 2.0.6 with 2701: several errors and measurement terminated

I noticed many of the exceptions are from TekVISA. The Keithley software such as KickStart will want the NI VISA. When installing, it should install the necessary NI VISA runtime. But it seems the TekVISA is used for the 2701. On 64-bit Windows 10, you can have multiple VISA vendors. And the VISA co...

Mauricio, I'm having difficulty to imagine how a ground loop is created. The connector config of the 6221 is just assigning the role to the inner shield. The two instruments can be floating with respect to chassis ground (use HI and LO of each) with a Gig Ohm or more of isolation from chassis ground...
