Data acquisition & USN52R

Data acquisition & USN52R

How can I do the data acquisition from the USN52R, this equipment has an auxiliary port but the output is in DC values, I need to get and RF signal for post-processing whit DSP tools.

Re: Data acquisition & USN52R
Do it by reading out the instrument digitally via RS232 - it is the only standard way. But I guess it is much too slow for a DSP.
Why don't you use a PC-Card based system for such an application. Then you can get access to the raw data as quick as possible. The USN52 is really the wrong instrument for this.
For a good performance you may use a standard PC digitizer slotcard with sufficient speed and dynamic (SONIXS, Signatec, GAGE, Spectrum, ACQIRIS). These cards often might be directly interfaced to a DSP.
And look for a good pulser/receiver board - that's all you need for optimum signal processing. If the receiver das DAC capabilities, don't forget to take this into account into your DSP routines.

Re: Data acquisition & USN52R
A new additiuon to our Digital Signal Processing product line is the newly introduced, 12 bit A/D board manufactured by Physical Acoustics Corporation. This 100 MSamples/second board interfaces (piggy-back using 1 PCI slot only) with an available 300/400 V. Pulser/Receiver board.

Contact Physical Acoustics Corporation for more information. www.pacndt.com

Undocumented commands of USN 52!
Hello!
Can anybody tell me something about undocumented commands of USN 52 (M4): DA, JD, JW, YP, YY?

Best regards...

Extended Range Variable Wall® Piping Calibration Blocks for Longseam Inspection

This set of two blocks has been specially designed for situations where ultrasonic examination tak
...
es place circumferentially or “around the curve” for applications such as inspection of longseam welds in piping and vessels. Jointly designed by PH Tool and Holloway NDT, the blocks feature side-drilled hole reflectors positioned within novel compound-curves, each with multiple thickness steps. The unique design results in a light and compact form factor, with the largest block weighing just over 15 lbs and spanning just 16 ¾”. Coverage is provided for nominal pipe sizes from 6” to 10” in the small block and 12” to a whopping 56” in the large block. The compound OD curves and multiple wall thicknesses actually exceed ASME requirements, providing exceptional signal response and measurement accuracy. Properly managing beam divergence off the ID and stabilizing beam skew due to probe rocking is essential to maintaining a consistent calibration when inspecting lengthwise on curved surfaces.

oved signal to noise ratio, characterize, size and analyze defects better with access to several wave mode views and save raw FMC data for higher quality analysis.  Some of the benefits are:
  • Beautiful Image! Easier to understand what you're looking at
  • Completely focused in entire image or volume
  • Much easier to define setups before inspection
  • Easier to decipher geometry echoes from real defects
  • Oriented defects (e.g. cracks) are imaged better
  • See image from different wave modes from one FMC inspection
  • FMC data can be reprocessed/analyzed without going back to the field
