nepouzivate nahodou nekdo PC zvukovku jako osciloskop? Ty programky vypadaji slusne a pokud staci rozsah f do 100kHz, tak asi neni co resit...
VA is a real time program which simulates a set of electronic instruments, such as:
·Oscilloscope (dual channel, xy, time division, trigger);
·Spectrum Analyser with amplitude and phase display (linear, log, lines, bar, octaves band analysis 1/3, 1/6, 1/9) ;
·Wave-form generator with "custom functions", triangular, square, sinus, white noise and pulse generation (NO ALIASING);
·Frequency meter (in time and frequency domain) and counter;
·Volt meter with rms and peak to peak display;
·Filtering (low pass, hi pass, band pass, band reject, notch, "diode", DC removal);
·Memo windows for analysis and file saving of time and spectrum displays;
·A true software digital - analog conversion (for complete signal reconstruction);
