flexrio stream to disk

[Jeff_Giacone]

I am looking for an labview example  that shows how to acquire data with a strobe clock and streams the data to a file on the computer

How can I determine what the maximum clock rate is for the data clocked by the strobe signal?

Tiger,

What type of flexRIO are you using?

Also, what exactly do you mean by "strobe clock"?

Tiger,

To best help you, in addition I will also need the following information about your setup:

1.) Adapter Module

2.) FlexRIO

3.) Chassis

4.) Controller (Mxi or embedded)

In general, the max data rates you will see for a PXI FlexRIO is 100MB/s and PXIe is 700MB/s.  You can go faster, but those are good, safe numbers.

NI PXIe-1082

NI PXIe-7962R

NI 6587

NI PXIe-PCIe8375

SMA-2164 with coax cable for loopback

I want to use the strobe input for clocking of receive data

Additionally would like to use the channel serdes and stream each data channel to separate files

I assume the the 700MB/S is per DMA stream(channel) or is it the total bandwidth for the instrument?

[Daniel-H]

Tiger,

Those values actually relate to the entire bandwidth of the device- not per channel.

[Jeff_Giacone]

I imagine that the bandwith of the write speed of the instrument is actually limited by the hard drive

[Daniel-H]

Tiger,

Possibly.  I guess you could think of the drive as the data sink side of the transmission.

You could design a system that buffered into RAM before writing to the drive if the drive was the limiting factor.
