Is it possible to start an analog channel data aquisition by another analog channel signal or a digital input line? Hardware: NI PCIMIO16E-1

A late response here but I would recommend that you create a VI that counts a fixed number of transitions (low to high crossing a given threshold). Do this for a certain sample set. Let's say 1000 samples. Then I would compare the count of transitions to the total number of samples collected. If you have fewer transitions for the given samples, you have a problem.

Hi Michael,

I solved my problem in a similar way. The VI aquires data over about 100 pulses and measures the time from rising to falling edges and from falling to rising edges. Because it is not pwm signal, these times have to be almost equal. If not, there is an error.

Is it possible to start an analog channel data aquisition by another analog channel signal e.g. a high pulse on channel 2 should activate a data aquisition seqence on channel 1.

I'm using a PCIMIO-16E NI A/D card.

Try reading the waveform-data (Y-values). Then use NI VI's (Math) to perform the integration.

Is it possible to start an analog channel data aquisition via a trigger signal which comes from another analog input channel. I'm using a NI PCIMIO-16E D/A card.

I'm searching a VI that is able to analyse a periodic pulse-signal with known amplitude and frequency and give out a warning as soon as one pulse is missing. The acquired signal don't need to be saved.

I'm using the "read from file" VI and sometimes it produces a one button

error dialog "not enough memory to finish this operation". Is there a possibility to disable this error dialog?

How can i determine the size of a cluster (it contains arrays and strings) in bytes?

I'm searching for way to programmatically create zip files.

The resulting VI should be able to take the path of the file to be zipped and create the corresponding zip file.

I got to change a protected VI and don't have the password.

How can I get it?
