Simple performance verification

[opalekj]

I wish to do a simple performance verification on 6035E and 6034E cards as follows: Input a 2Vpp 1kHz square wave into each analog input on the BNC-2110. Can anyone tell me what tolerances I might allow when viewing the results on the monitor using the scope function?

Thank you,

Jim

Hello,

I am unfamiliar with Scope function that you mentioned. Maybe if you could shine a little more light on this I might be able to better help.

When you say tolerance of a measurement, I'm going to think you are looking to find some specifications for your device. You can find some of the published accuracy numbers accuracy for your devices in the E Series User Help file.

If I'm totally missing on what you really want to know, post back and I'll have a look.

Hello Jared, and thank you for replying.

The VIs that we use in the scope program to make measurements are:

AI Acquire Waveform.vi
Amplitude and Levels.vi
Extract Single Tone.vi

We have also selected a +5 to -5 Volt range.

I must admit to being confused by NI's published specs on these boards, that is why I am hoping to have a more familiar spec like 2Vpp +/- xx and 1 kHz +/- xx.

Thank you again,

Jim

Hi Opalekj,

The specs say that at +/- 5 volts, the error on a single point acquisition will be +/- 0.467 mV. And that the resolution at that range is 0.542 mV. The accuracy of an averaged reading (using dithering) is quite better with an error of +/- 0.0412 mV. This data is for voltage readings regaurdless of frequency. Signal frequency is determined in software from the array of voltage data points.

I hope this helps.
