Hi,

When trying to set up AC coupling on my TBS2000B/MSO2024B through the trigger mode, it only seems to have the option for DC, HF, and LF. Does AC needs to be purchased, or if there is something else I am missing?

Hello,
I was looking at the specifications for MDO4034B-3 oscilloscope. Noticed that there was a DC gain accuracy, but no AC accuracy. My scope is setup for 4.00ms and 2.00V per division. Running 1ms pulses for with a high value of 8.7V.

If there is an AC gain accuracy spec for my application, please let me know.

My TBS1032B is no longer functioning properly. I was working on a 9 V circuit when it suddenly stopped reading, it appeared that the parameter acquisitions for channels 1 and 2 failed, along with self-calibration. My power cycles are at 386 and that his error log is 1 of 1 with no errors. Do you have any suggestions on how to resolve this?

I need to generate 9V@100A DC. Can you provide a product reccomendation?

Hello, I have 11 probe tips model # 650-6122-00 that need repair. Can you please provide information on how to get diagnostics and repair.

Hello,

I am a professional music producer / mixer / recording studio owner, & a bit of an amateur tech. I'm ramping up my knowledge as a tech & beginning to run into problems that require a scope to access, & am considering buying your TBS1052C.

Some of my tube pre-amps & compressors run off of 600V DC, & I see the TBS1000 series has a max input of 300V RMS.. My question is, is it possible to simply buy a set of attenuator probes? Or will this setup potentially damage the scope?

I'm also all ears if you think you produce a scope that is better fit for my application.

Thanks for your time!

My TDP0500 failed calibration due to the 4.25V range is not working. The 42V range passed calibration. Any ideas on how to resolve this?

My 2450 seems to be restricting voltages to 40 V. For example, I put a 50 V input into the device and received a readout of 40V. Anything below 40V below worked fine. What might the issue be?

We intended to know the resistance variation of the object under the application of the pressure by 4-wire resistance measurement. The object itself has 2-10 milliohm. Under the application of the pressure, it is expected to vary and we need to know its difference accuracy within 0.4 milliohm. In other words, we need the digital multimeter which can differentiate the resistance change within 0.4 milliohm or so. We have Keithley 2000, Keithley 2400 and Keithley 2182. Does one of them work for this purpose? Do you have any suggestion? Thanks,

I have one Keithley 2000 digital multimeter. I would like to do the 4 wire resistance measurement with the resistance in milli-ohm scale. I am wondering if Keithley 2000 provide constant voltage or constant current during 4-W resistance measurement. In either cases, what is the supplying voltage or current?
