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.
