measure waveform rise time with IVI step

[Elik]

I'm trying to simulate measurement of wafeform rise time through IVI step TS 4. How should I  feed the Scope IVI step with waveform and then get the calculated rise time in simulation mode(I do not have the Scope yet.

Thank you.

Hi,

You can do it either with the InitWithOptions function and set the Option String so that Simulate=1

or you can do it in NI MAX. Select the Logical Address you are using and enable Simulate.

Hi,

Thank you. So far it is simple, but I wonder if there is a way to feed to the IVI step through simulation waveform like square wave and different frequencies. I've tried using TDS 2000 series but I get the same data results.

I configure it as Normal Acquisition

Advance Tab Low Reference 10, Middle 50 and High 90.

Channels Tab, left the defaults except Maximum input frequency which I configure with variable

Trigger Tab Type Edge, Source Channel 1, Coupling DC, Slope Positive, Level 0.5

Extension Tab, Waveform Measurement.

I also set a step Read and set one of the channels to read Rise Time.

Although the waveform change The data from step results which I suppose give you the rise time stay the same.

Is there any way to change the waveform type and the rise time through the IVI step?

Thank you.

Hi, Further more I've tried to setup the IVI driver with parameter WAVEFORM set to 2 for square wave with no visual effect. I'm not sure what is the simulation active panel means. I could find  the IVI Simulator Setup Dialog box anywhere.The IVIScope panel does not allow to configure WAVEFORM parameter. Does NI IVI driver help refer only to NI Scope?

As far as I know the TDS2000 driver is an NI driver.

Thank you.
