/dev/dsp - Audio sound recording via /dev/dsp. Two 8-bit analog channels at 8000 S/s to 44100 S/s. Left and right audio is connected to A and B inputs respectively. Use an external mixer program to select which sound inputs to record. AC coupled, voltages unknown, 256K sample memory.
EsounD - Shared audio sound via the Enlightened Sound Daemon. This is great for watching music but support for it is an option at compile-time. EsounD is auto-detected and preferred over /dev/dsp.
ProbeScope / OsziFOX - Radio Shack ProbeScope, Cat. No. 22-310 is also known as an oszi‐FOX. This handheld probe sends its data through a serial port. It samples one channel at 6-bits up to 20 MS/s with 128 samples of memory. Real voltages are labeled in sample ranges from 1 volt to 100 volts. If a ProbeScope is detected, it is connected to the A input.
Bitscope - Bitscope (www.bitscope.com) is a mixed-signal capture engine which is accessed through a serial port. It simultaneously samples a digital 8-bit port and two analog channels at 8 bit resolution at up to 25 MS/s or more. If detected, Channel A and B are connected to X and Y while the Logic Analyzer is connected to C.
Scartiamo immediatamente Bitscope e ProbeScope. Sono hardware aggiuntivi , sicuramente utilissimi ma totalmente incompatibili con lo sciopero della spesa che ho indetto anni fa e che porto avanti testardamente ad oltranza. Basta poi cercare in rete o consultare i siti suggeriti per farci passare la voglia di acquistare....per me costano decisamente troppo e mi devo accontentare di due canali (limitazione anche in frequenza)....pazienza.
