We have noticed that the TSP EC codes not working on Keithley 2450 with upgraded the firmware.

Can we have new TSP codes for the new firmware?

Thanks!

Thank you!

That's great! 

Thank you for your replay.

Currently, Windows 7 (32bit) is the operation system of our 4200. And the Visual Studio 2015 has been installed on this system. KULT works fine, the C-code can be complied in KULT, and the existing lib (KITE 9.1 SP7) can be built without any error.

We can use the existing sample libraries 4284 to control Agilent LCR.

We are trying to figure out is there any available C-code for 4200 to control the external 2450. 

 

Recently, there are several new SMUs arrived in my Lab, including 2450, 2461 and 2601B. We have ordered Kickstart IV for these SMUs, however, Kickstart 2.11 is only for WINDOWS 10.

We are trying to integrate these new SMUs into 4200 system using UTM. 

Is there any available UTM modules for these SMUs?

Hi, recently we are trying use the 4225-RPMs as close as possible to the DUT, thus we need longer cables to connect the 4225-PMU to 4225-RPMs.

I have searched the previous topics from the old web forum and found this:

"The cables which connect the 4225-PMU to 4225-RPMs are the same as HDMI cables"

So can we use the HDMI cables (HDMI 2.0 or 1.4) to connect the 4225-PMU to 4225-RPMs?

YES, I understand that the 2601B-P-INT is used for BNC connections.

However, we are going to connect 2601B-pulse to the Triax connectors of the prober station for low current measurement.

In addition, if both the 2601B-P-INT and the guard were used, the BNC outside shell would be connected to the guard, which is unsafety.


 

Hi, I have noticed that the PIN definition of 2601B-pulse rear panel is quite confusing as compared to those of 2602B or 2612B. 

The following figs are adapted from the manuals of 2601B-pulse and 2600B.

The manual does not clearly indicate the PIN definition of Channel A: DC/pulse and Channel A: DC.

I guess:
For Channel A: DC,
PIN 1 is LO,
PIN 2 is SENSE LO ,
PIN 4 is HI,
PIN 8 is SENSE HI,
and PIN 3 5 6 7 are GUARDs?

For Channel A: DC/pulse,
PIN 9 is HI,
PIN12 is LO,
PIN 15 is SENSE HI,
PIN 16 is SENSE LO,
and PIN 10 11 13 14 are GUARDs?

Are these PIN definitions correct?

Thanks!


 

YES, terminal 4 is not GND and actually it is connected to the collector of one BJT.<br> Using a resistor between terminal 3 and 4 is a good idea.<br> However, I am afraid it may break the symmetry of the entire circuits.<br> So, I guess I have to use external DMM 7510 or 2600 to measure the current.<br> Thank you for your help!

Hi, there is one 4200 system with 5 SMUs in my lab.<br> Recently, we are going to use the system to measure IV curves for our designed PCB board as shown in the following figure.<br> Basically, there are four terminals on the PCB:<br> terminal 1 is Vin,<br> terminal 2 is GND<br> and the other two&#160;terminals (terminal 3 and 4) are used for current measurements.<br> The voltages of terminal 3 and 4 are dependent on the current.<br> We want to sweep the Vin at terminal 1, and meanwhile measure the current between terminal 3 and 4.<br> How to set SMUs for this measurement since all the Lo&#160;terminals of SMUs are connected together in 4200 system?<br> Should I need one additional 2400 or 2600 to perform this measurement?
