2.11The CD shall contain all the calibrationThe CD shall contain all the calibration files required for each lot in the contract.

2.12The requirements for e-mails are as followsThe requirements for e-mails are as follows:

2.12.1After a lot has been accepted, theAfter a lot has been accepted, the calibration data files shall be delivered via e-mail to the first e-mail distribution list found in BLK 16. The data files delivered in this e-mail shall contain all the calibration files required for each buoy in the lot. This e-mail shall include attachments of the baseline and secondary calibration data sheet files.

2.12.2For acceptance testing a different e-mailFor acceptance testing a different e-mail distribution list is found in BLK 16. These files shall contain the calibration data for each sonobuoy in the test sample. The data shall be delivered concurrent with the test samples.

The baseline system calibration data file shall be in the same format as (6.2.1) the baseline system calibration data sheet except for the media, and the file shall not contain extraneous spaces or blanks. Each serial number and its related data are distinguishable as a record. The serial number shall just include the last digits. Each line entry is a record and shall be distinguished by its delimit and a carriage return.

2.14The secondary calibration data file shall beThe secondary calibration data file shall be named in accordance with paragraph 3.4.1 with the sixth character being a "T". The secondary calibration data file shall be in the same format as paragraph 3.4.2 the secondary calibration data sheet except for the media, and the file not contain extraneous spaces or blanks. Each channel number and operating depth with its related data is distinguishable as a record.

3ContentThe content for Calibration Data shall be as follows:

3.1The contractor shall compile and deliverThe contractor shall compile and deliver calibration data. The calibration data shall be referenced to a signal, in SPL in dB relative to 1uPa, which produces 19 kHz of deviation in the sonobuoy. The baseline calibration data shall be the amplitude of signal in dB relative uPa minus 116 dB relative uPa. Secondary calibration data shall be in dBs. The addition of the secondary calibration data to the baseline shall correct the baseline system calibration due to changes to the operating depth and RF channel.

3.2The Sonobuoy Sonic System Frequency ResponseThe Sonobuoy Sonic System Frequency Response Data will consist of the baseline and secondary system calibration data. The baseline system calibration data shall be representative of the sonobuoy being deployed at (D3) 400 ft and RF channel 1. Secondary calibration data corrects the baseline system calibration based operational setting.

3.3No more than three (3) calibration curvesNo more than three (3) calibration curves, contained in (2) tables or files, shall be supplied per sonobuoy sensor to allow for correction factors associated to RF channel and depth.
