What is a CH1 file?

CH1 files mostly belong to OxySoft NEO/OXYVIEW, GraphPad Chart. CH1 files are not general documents; they are specialized files used by specific scientific software.
One type follows the OXY2_4.01 standard for oxygraph instruments. Such files, often called Oxygraph data files, store experimental measurement data including calibration and channel-specific (CH1, meaning Channel 1) readings. They are typically managed with software like OxySoft NEO/OXYVIEW.
Another type is identified as a GraphPad Chart File, used to save chart configuration and visualization settings. This variant is associated with the GP2CHART system and is designed for scientific plotting.
Details include:

Creation: The file structure is defined by the originating instrument or software.

Usage: Open with the vendor-recommended application (OxySoft NEO/OXYVIEW for oxygraph data or GraphPad Chart for chart files).

Content: The file may embed extra metadata essential for accurate data interpretation, such as calibration data.

FilExt.com note: Recognize the file's origin to select the proper viewer. If you need more details on an oxygraph data file, you might check additional resources from the manufacturer (for example, visit their website if available).

CH1 file format:

If you can determine the file format, the associated program can also be determined. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. So a detailed analysis of a file is vital in order to determine the format and the associated program. Our evaluation of the CH1 files looks like this:

An CH1 file includes various formats for various programs. But the following two file formats are common:

• 25% of all CH1 files start with the bytes DTLG crucial for this file format. These files contain neither text nor words, but only data. The file size is in the range of 11 KB to 21 KB. The file type is relatively new. Certain words are almost always found in the files, such as DTLG. The file name 20.ch1 or 40.ch1 is characteristic of these files.
• 6% of all CH1 files start with the bytes E0 crucial for this file format. The contents of these files are easily readable with a text editor. The average file size is 17 KB with most files being between 6 KB and 19 KB in size. Several words can almost always be found in the files, e.g. Channel 1: Small Patch 5 x 5mm and E0188 SWV:OXY2_4.01 PICSWV:4.01 DFV1.0.

All other CH1 files (69%) have no consistent format, frequently e.g. CHART. Sometimes used for sample, piano, attack, bass, drum or kits. Drag & drop your file here to see the file format and a preview of your CH1 file!
