Mekre,

Here is your last reply from a thread that is now locked.  I appreciate your help but I need more direct information.  Recall e2e.ti.com/.../952033. The info you supplied does not seem be be able to be entered into the PGA460-Q1 EVM GUI. There is a parameter save and load feature on the Data Monitor | Interface Mode form.  Can you give me a file with the correct values I can load?  If not, can you tel me how to enter the values below.  The videos and other links are fine for background info but do not directly address my needs.  Again, I bought TI components that I expeted to work straight out of the box and they are not.

Hi Robert,

In one of our code examples that used the same transducer used in the PGA460PSM-EVM, the following default values were used:

                                 TVGAIN0 = 0x9D;

                                 TVGAIN1 = 0xEE;

                                 TVGAIN2 = 0xEF;

                                 TVGAIN3 = 0x2D;

                                 TVGAIN4 = 0xB9;

                                 TVGAIN5 = 0xEF;

                                 TVGAIN6 = 0xDC;

                                 INIT_GAIN = 0x03;

                                 FREQUENCY = 0x32;

                                 DEADTIME = 0x80;

                                 PULSE_P1 = 0x08;

                                 PULSE_P2 = 0x12;

                                 CURR_LIM_P1 = 0x72;

                                 CURR_LIM_P2 = 0x32;

                                 REC_LENGTH = 0x09;

                                 FREQ_DIAG = 0x33;

                                 SAT_FDIAG_TH = 0xEE;

                                 FVOLT_DEC = 0x7C;

                                 DECPL_TEMP = 0x8F;

                                 DSP_SCALE = 0x00;

                                 TEMP_TRIM = 0x00;

                                 P1_GAIN_CTRL = 0x09;

                                 P2_GAIN_CTRL = 0x29;

You can use these values as a starting point and then change values as necessary to optimize for your specific system and target. The following video series provides examples on configuring the GUI:
