Hello,

I encounter the following issue for bandwidth (-3 dB) measurement.

If the X Scale is set to Log initially, the DDP will not show the bandwidth information as shown in the picture below.

I have to use linear for X Scale to see the bandwidth data.

Is it a bug or not ...

Thank you.

I hope this can be avoided or selectable in future release.

When I switch from other type(e.g. coherence function) back to Amplitude spectrum, some settings (X, Y scale, range) are automatically changed to default. What should I do to avoid this?

I got it. Thank you.

In order to see the delta time of two markers, I have to place the markers on different channels. This is what I am seeing. Is it correct?

Hello,

I want to do multiplication for a measured waveform with a predefined time-domain waveform with the same number of samples. Is it possible in MI?

Thank you.

I found the answer in product page.

Can i have two VT IEPE-2Gxx connected to a PC to get a 4-ch platform?

Is it possible to use DDC data input of DDP?

I have DDC showing energy time curve (envelop) of channel B. Can I define DDP to measure the time from a peak (first or second) to a specified energy level? This is similar to decay time measurement. A screen shot is attached.

I need pinknoise with high-pass at 150 Hz together with a < 10 Hz tone (known as pilot tone). The signal is used to power test loudspeaker drivers. The tone in low-level is used to measure coil resistance. My audio interface uses ASIO driver.

I was thinking to mix the two signals externally (e.g ...
