I am looking to capture and data record signals going into my MSO4034, OpenChoice is one option, but I would like to know what all my options (preferably the free options) so the students can collect data.

I wish to capture/record/save file 5 seconds of time vs voltage data for 4 channels. I wish to start the data capture when channel 1 exceeds 0.1V. Channel 1 is a PWM signal at 20kHz. Channels 2-4 are 20kHz as well. I am sending a PWM signal into a device (channel 1) and wish to record the response over 5 seconds for channels 2-4.
It seems all I have been able to record/save file is what is present or viewed on the oscilloscope screen. This means the x-axis (time) on the screen needs to be about 6 seconds. I capture/record that data in the "c-drive" onboard the scope. When I transfer it off the scope to my computer for post processing the resolution is just not there. The data is sampled at a very low sampling rate so all the details are lost. I expect 5 secs x 20000 data points/sec = 100000 data points per channel and the data is just not there. The square wave PWM signal is a course sinewave. When I change the time axis cover just a few microseconds the detail is there in the signals.
Is it possible to capture data at full resolution and not just what is showing on the screen? I need to capture about 5 to 6 seconds of all 4 channels at microsecond or better resolution. I have read and re-read the manual but it provides no guidance on this.

Our design group for is currently trying to run CV tests, both high frequency and low, and we ran into an issue. ACS doesn’t have any test modules for the 590 or 595. We wanted to know if there are any test modules that we can import and that can be found online. This would save us time and effort so that we don’t need to script a new one. If we did need to script a new one could we potentially use the script from a 4200 CVU model? We are also using Keithley source meters to pair with all of this (2636B).

I'm currently trying to perform a CV measurement with my 2400 and I'm confused about the connections working the counter and reference electrode. Do you have any schematics to help connect to the 2400. If this unit is not capable, would using my 2636 be better for this?

how many current probes can i connect to the DPO 2024B or what is the max current that the scope can provide for current probes?

Are P5200A and A622 compatible with the TDS 2024 ?
Also are the drivers for the TBS 2204B compatible with the older TDS 2024?

I want to export data from the 2611B to my computer. When I export, I see the graphs in a jpg file, but I'm wondering if there's a way to view the values of the data in a CSV file. I'm currently using the Keithley IV Software with the 2611B.

Where can I find Country of Origin and HTS Codes for my DMM6500?

Are there any any app notes of how to count the number of trigger events with this scope?

Hello, Would I be able to purchase recovery CDs for a TDS5034B? My scope fails to start the tekscope application due to numerous driver and library load issues. Its unclear how this got corrupted, but its clearly due for a system reset.
