Measure Period with error out.vi

[labview1958]

I am using LV6.0. Can Measure Period With Error Out be found in the functions panel? If not where it is? If not there can it be imported into LV6.0?

labview1958,

Are you looking for a specific VI called Measure Period with Error Out.vi or are you asking about any general function that can be used to measure the period of a signal and includes error handling? If you are looking for a specific VI, I'm unaware of it, so I won't be much help there. If you're looking for any function to do it, have you looked at the VIs called Measure Pulse Width or Period.vi or Pulse Width or Period Meas Config.vi? They are located in the Data Acquisition>>Counter palette. The Measure Pulse Width or Period.vi does not include error handling, but it would be extremely easy to add it. The Pulse Width or Period Meas Config.vi DOES contain error handling, but it only configures the counter to measure the period, it doesn't actually measure it. These, of course, are for TTL signals coming into your hardware device. If you are reading waveform data from a file and want to calculate the period of that signal, these won't do much for you. So what exactly are you wanting to take a period measurement on, a physical signal, physical signal data points from a file, or some other method?

I am measuring a low frequency  TTL signal using the one counter method. Thus I am using measure period.vi. However I would like to do some error out. Thus I am looking for measure period with error out.vi. I cannot find in the functions panel.

It doesn't exist.  You can make a copy of the measure period vi and add you own error checking by modifying the block diagram.  Then save the vi under a different name, like measure period with error out.  If you put your new vi in the user.lib folder, it will appear on the function palette under user libraries.
