(Video) Keithley 2450 Source Measure Unit (SMU) Review and Experiments

[Hugoneus]

In this episode Shahriar reviews the new Keithley 2450 Source Measure Unit (SMU). This model, which is the successor to the widely adopted Keithley 2400, offers performance improvements as well as a brand new interface platform with multi-point touch screen.

The review demonstrated the instruments GUI, scripting capabilities through the TSP interface and various performance parameters. Furthermore the scripting features are used to measure super capacitor capacity, the performance of a wireless charging system, characterization of optoelectronic components and semiconductor elements.

Thanks for another superb review and reassurance, good things come in pairs!

Due to guys like you, Dave and robrenz (and maybe the current 10% promotion at Keithley), I placed an order for the 2450 last week.  I was hoping you'd tear it down so I didn't have too,

Maybe in a different video. These are both recently calibrated units.

Big fan of Hugoneus here,

I got a Keithley 220 after watching his epic video..

Now I am at work and I can not watch it. I can´t wait.

If you love the EEVBlog and you are not subsribed to the Signalpath channel then something is wrong with you, go to the doctor (or check if your internal power supply is working...).
I just love that channel as much as the EEVBlog one.

Nice video Hugoneus

Your review has more views in one day than my 2450 review has in 10 months

Get a cat and a bottle of wine, Robrenz.

Haha... Yup!

[robrenz]

It also could have to do with the fact that Shahriar's electronic knowledge compared to mine is orders of magnitude greater than the 300:1 video view ratio.

For your own use?

When you own a 2450, the winner is, you!

Me, myself and I,

Great video as always! I really like the well-prepared experiments.

One thought about the TSP stuff: At first sight it seems like their TSP language is a completely custom job. I'm wondering why they reinvented the wheel and didn't adopt something common like Python or Javascript.

NIH of course. Irritatingly enough, everybody seems to do it.

Haha... Yup!

Nothing like a stack of awesome test gear without the leads plugged in and topped with a Cat..

Me, myself and I, 

I want two!  One to check the other to make sure it isn't telling me a story.

Oh yes, the never ending cycle of suspicious instruments!

[SeanB]

If you have one multimeter you either trust the readings implicitly or not. With more than one you are always in doubt.

then again I still have a $1 multimeter that I use every so often, as it is a perfect method to test cells for charge state. Can measure open circuit voltage and load it with a current to see internal resistance.

If they don't agree, how do you know which is correct? Better get a third.

[German_EE]

This is why you have standards in a workshop/lab. A voltage standard is a good start but when you add some 0.01% resistors you can verify both the ohms and mA ranges. Now you add either a GPS or Rubidium locked frequency reference and you can verify your measurement of both time and frequency.

As for the 2450, it could replace at least two of my instruments and maybe a third. Can it operate as an electronic dummy load? I think yes but I am not so sure.

Oh yes, and hello from another cat person, we have two.

[dr.diesel]

Can it operate as an electronic dummy load? I think yes but I am not so sure.

Yes, but can only sink 1-Amp.

Yes, but can only sink 1-Amp.

Yes, true. This would be more of a precision load. Also remember that this instrument can jump from any I/V quadrant to any other.

[dr.diesel]

precision load.

I'm pushing it here, but,  O0

Thanks for a nice review again.

Now it is difficult to decide between the Keithley or the Keysight Source Meter.
But both are so expensive!

[robrenz]

The Agilent does have a few higher capacities in certain areas especially pulse mode and AWG like features. But My 2450 spec review has the comparable Agilent in it. The Keithley wins on accuracy specs in almost every area.
