This may be useful if the device was not detected at startup. A serial device is turned on only if it is found active on a serial port. Enter Clear and refresh the entire screen. You are prompted for the filename and asked for confirmation to overwrite if it already exists. # Save current settings and memory buffers to a file that can be loaded later. Escape Immediately quit the Load a previously saved file. The following single key commands are available:? Toggle verbose key help display mode. In verbose key help mode, each available key is shown on the screen in (parentheses). 3 Run-time Keyboard Controls Oscope is an interactive program and can be completely controlled from the keyboard at run-time. Bitscope will eventually be controlled through a separate dialog window. Please refer to your ProbeScope or oszifox Owner s Manual for operating instructions. Oscope has no physical control over the ProbeScope/osziFOX which is controlled by its own switches and builtin menus. Some of the controls below apply only to the sound card and are labeled as such. See the -x and -z options and the ENVIRONMENT section below for more details on how the above devices are detected. Bitscope support is currently under development and not yet fully functional. If detected, Channel A and B are connected to X and Y while the Logic Analyzer is connected to Z, disabling all sound input. It simultaneously samples a digital 8-bit port and two analog channels at 8 bit resolution at up to 25 MS/s or more. 1ΔΆ Bitscope Bitscope ( is a mixed-signal capture engine which is accessed through a serial port. If a ProbeScope is detected, it is connected to the Z input. Real voltages are labeled in sample ranges from 1 volt to 100 volts. It samples one channel at 6-bits up to 20 MS/s with 128 samples of memory. This handheld probe sends its data through a serial port. ProbeScope / OsziFOX Radio Shack ProbeScope, Cat. EsounD is auto-detected and preferred over /dev/dsp. This is great for watching music but support for it is an option at compile-time. EsounD Shared audio sound via the Enlightened Sound Daemon. AC coupled, voltages unknown, 256K sample memory. Use an external mixer program to select which sound inputs to record. Left and right audio is connected to X and Y inputs respectively. Two 8-bit analog channels at 8000 S/s to S/s. Signal input devices currently include: /dev/dsp Audio sound recording via /dev/dsp. Signals may be displayed, saved, recalled, and manipulated by math functions. It graphically displays signal amplitude or bit logic as a function of time. 1 oscope xoscope Digital Oscilloscope via Sound Card or Other Hardware 1 Synopsis oscope xoscope 2 Description Oscope is a digital real-time oscilloscope.
