Response File
First, refer to the Playback manual included in the documentation binder with the rest of the Nanometrics manuals.  This manual gives a description of the response.exe command used to generate the seed.rsp file.

In fact, this step is simple.  All you need to do is type the command 'response filename' at the C command prompt.  The filename field specifies the name of the response file that is being generated.  The name of the response file should correspond to the one shown in your Naqs.stn file.  In your particular system, the Naqs.stn file shows that you need to generate a response file for a REFTEK sensor.  The 'response filename'  command will run the response.exe program that will generate the response file.  The program will prompt you to enter three input parameters, the sampling rate, the IIR corner frequency (lowpass) and the sensor type.

So, enter the sampling rate you are using.  

For the IIR corner frequency, enter '0' if the DC removal is OFF, which should be the case normally.  Otherwise, enter the frequency that your digitizer is configured to.

For the sensor type, the correct sensor type should be chosen from the list of supported types displayed by the software.  If the used type is not in the list, then choose any other type and move to the next step.  Your particular sensors are not included in the list.

After the 3 parameters have been entered, the program generates the filename.rsp file and exits.  Use a text editor to open this file which is usually located on the C: drive.  The file contains the stages of the sensor digitizer system.  The file is divided into blocks where the first block is the header, which is followed by the nine stages of the system.

IT IS IMPORTANT to verify the header, as well as the first, second and third stages and CORRECT THEM.  

- Correct the header: The header should be corrected to contain the correct sensor information.

- Correct the first stage: The first stage should be corrected to include the correct parameters pertaining to the sensor you are using.  Check your sensor manual for this information.

- Correct the second stage: The second stage is ONLY corrected for the gain which should correspond to the digitizer front-end gain of your system and depends on the gain resistors used in the ADC board.

- Correct the third stage: The third stage should also be corrected for the gain.  However, the gain here corresponds to the ADC sensitivity.  Enter the correct ADC sensitivity of your digitizer in the appropriate field.

After all the above steps have been performed, the response seed.rsp file should be correct and ready for use.
