Regarding the line/depth with low correlations the explanation is probably that in the ... 2008-11-21T14:53:18Z Comment http://www.nortek-as.com/forum/hr-profilers/424469701/492553563/view Hi Sven, Thanks for that.  So yes, I'm an idiot -- I just wasn't paying enough attention (I'm too used to the low res aquadopps and thought I knew what ... 2008-11-20T01:01:07Z Comment http://www.nortek-as.com/forum/hr-profilers/424469701/258468762/view Hi Julia, The hdr-file that is generated when you convert the data to ASCII shows you the format of the various files that are generated in the ... 2008-11-19T21:20:21Z Comment http://www.nortek-as.com/forum/hr-profilers/424469701/810546124/view Hi again,   When we deployed our HR Aquadopps in burst mode (in single or 3 beam mode) we find the second depth bin has correlations of greater than ... 2008-11-19T19:03:06Z Comment http://www.nortek-as.com/forum/hr-profilers/113432221/284584046/view Hi Julia, You are absolutely right, I missed the fact that this happens on both instruments. Not to mention that we very rarely see connection problems ... 2008-11-07T09:35:26Z Comment http://www.nortek-as.com/forum/hr-profilers/113432221/958599306/view Hi Sven, So the error code does indeed give us a value of 1 for those points when the compass and tilt measurements are zero/90.  I'll upload the hdr ... 2008-11-06T23:04:14Z Comment http://www.nortek-as.com/forum/hr-profilers/113432221/958599305/view Hi Julia, The compass update rate is a bit misleading when you do burst measurements. During burst measurements the compass (including pitch and ... 2008-11-06T11:11:42Z Comment http://www.nortek-as.com/forum/hr-profilers/113432221/958599304/view Hi, I noticed something odd when processing our HR data recently.  We were sampling a single beam at 8Hz with a compass update rate of 1s.  The ... 2008-11-05T00:22:37Z Comment http://www.nortek-as.com/forum/hr-profilers/4042362/650549789/view Darn, hate to be the first to try ...

What if the Vector's sampling ... 2008-07-20T17:11:56Z Comment http://www.nortek-as.com/forum/hr-profilers/4042361/645687304/view Dear Ayal, The extended velocity range that we have now implemented in the 2 MHz HR AquaDopp Profiler increases the product of velocity magnitude and ... 2008-07-11T07:07:49Z Comment http://www.nortek-as.com/forum/hr-profilers/4042361/451460659/view Hello, Regarding the recent update of the 2 MHz HR AquaDopp capabilities, could someone inform about the new "rule of thumb number" for the product of ... 2008-07-07T14:42:43Z Comment http://www.nortek-as.com/forum/hr-profilers/917114832/695611807/view More information about Measurement Load and Pings per Sample: The measurement load works much the same way as for the standard Aquadopp ... 2008-07-02T13:54:41Z Comment http://www.nortek-as.com/forum/hr-profilers/917114832/186916808/view Hi, there -- this is a bug.  The number that you see in the greyed out box should be the measurement load that is actually used during the data collection ... 2008-06-27T11:39:39Z Comment http://www.nortek-as.com/forum/hr-profilers/917114832/839993861/view Can you please describe how to use the HR Profiler software to determine how many pings will be sent per sample?  Is the answer pings/beam or total ... 2008-06-24T17:27:43Z Comment http://www.nortek-as.com/forum/hr-profilers/351501809/820772879/view More information on correlation (from Atle): The correlation in the HR means exactly the same thing as it does in the Velocimeters/ADVs.
