Oscilloscope accessories commonly include oscilloscope software and RS-232 or USB cables for connecting an oscilloscope to a computer. Oscilloscope software for PC enables a technician to output data about a device's electrical signals to a computer for analysis. With oscilloscope software, the data can be charted or graphed for use in reports, documentation, or archives. Software can compare electronic signals from multiple devices during the development or troubleshooting of electronic equipment. Some software allows technicians or electrical engineers to automate test procedures and create customized reports and testing procedures. Other accessories for an oscilloscope include batteries, carrying cases, probes, ground leads, or adapters. An oscilloscope battery is typically rechargeable for use in portable oscilloscopes.
