====== netacquire-pcm-sine-wave ====== [[http://www.irig106.org/sample_data/netacquire-pcm-sine-wave.zip]] These files contain floating point representations of a sine wave. The format of the data is: ^ Byte ^ Length ^ ^ ^ Offset ^ Bits ^ Description ^ | 0 | 16 | Frame sync pattern 0xeb90 | | 16 | 64 | IEEE-754 floating-point value sine wave 1 | | 32 | 64 | IEEE-754 floating-point value sine wave 2 | | 48 | 64 | IEEE-754 floating-point value sine wave 3 | | ||| | Final 2 Bytes | 16 | Unsigned integer sequential count | These data sets are also interesting because time packets occurs at a 100 Hz rate. Most data sets have time packets at a 1 Hz rate. ===== Message Data Format ===== File Name : netacquire-pcm-sine-wave-msg_20112018.ch10 File Size : 8,298,696 bytes Recorder Manufacturer : NetAcquire Recorder Model : Recorder Firmware : IRIG 106 Version (Data) : 106-05 or earlier IRIG 106 Version (TMATS) : 106-07 Indexing : Enabled Events : Disabled Recording Date / Time : 11-20-2018 Data Start Time : 324:22:52:22.470 Data Stop Time : 324:22:53:24.609 Data Types : Channel Data Type (Type Num) Packet Count ------- ---------------------- ---------- ------------ 0 User Defined (0x00) 2 0 TMATS (0x01) 1 0 Index (0x03) 8 1 Message (0x30) 705 65535 Time (0x11) 6195 ===== PCM Throughput Format ===== File Name : netacquire-pcm-sine-wave-thru_20112018.ch10 File Size : 8,190,452 bytes Recorder Manufacturer : NetAcquire Recorder Model : Recorder Firmware : IRIG 106 Version (Data) : 106-05 or earlier IRIG 106 Version (TMATS) : 106-07 Indexing : Enabled Events : Disabled Recording Date / Time : 11-20-2018 Data Start Time : 324:22:55:17.490 Data Stop Time : 324:22:56:19.630 Data Types : Channel Data Type (Type Num) Packet Count ------- ---------------------- ---------- ------------ 0 User Defined (0x00) 2 0 TMATS (0x01) 1 0 Index (0x03) 8 1 PCM Format 1 (0x09) 705 Throughput 65535 Time (0x11) 6195 ===== PCM Packed Format ===== File Name : netacquire-pcm-sine-wave-pack_20112018.ch10 File Size : 8,098,408 bytes Recorder Manufacturer : NetAcquire Recorder Model : Recorder Firmware : IRIG 106 Version (Data) : 106-05 or earlier IRIG 106 Version (TMATS) : 106-07 Indexing : Enabled Events : Disabled Recording Date / Time : 11-20-2018 Data Start Time : 324:22:53:38.370 Data Stop Time : 324:22:54:39.153 Data Types : Channel Data Type (Type Num) Packet Count ------- ---------------------- ---------- ------------ 0 User Defined (0x00) 2 0 TMATS (0x01) 1 0 Index (0x03) 8 1 PCM Format 1 (0x09) 690 Packed with Frame Sync 65535 Time (0x11) 6066 ===== PCM Throughput and Packed Formats ===== File Name : netacquire-3-pcm-sine-waves_20112018.ch10 File Size : 28,399,136 bytes Recorder Manufacturer : NetAcquire Recorder Model : Recorder Firmware : IRIG 106 Version (Data) : 106-05 or earlier IRIG 106 Version (TMATS) : 106-07 Indexing : Enabled Events : Disabled Recording Date / Time : 11-20-2018 Data Start Time : 324:22:51:11.300 Data Stop Time : 324:22:52:15.984 Data Types : Channel Data Type (Type Num) Packet Count ------- ---------------------- ---------- ------------ 0 User Defined (0x00) 2 0 TMATS (0x01) 1 0 Index (0x03) 8 10 PCM Format 1 (0x09) 734 Throughput 20 PCM Format 1 (0x09) 734 Packed with Frame Sync 30 Message (0x30) 645 65535 Time (0x11) 6451 ~~DISCUSSION~~
