Software
PicoLog for Windows	PicoLog data acquisition software can collect up to 1 million samples. Features include: Multiple views — view data as a graph, spreadsheet or text Parameter scaling — convert raw data into standard engineering units Math functions — use mathematical equations to calculate additional parameters Alarm limits — program an alert if a parameter goes out of a specified range IP networking — transfer measurements via a LAN or over the Internet Operating systems supported — Microsoft Windows 7, 8 and 10
PicoLog languages	Full support for: English, Français, Deutsch Menus and dialogs only for: Italiano, Español, Svenska
PicoScope 6 for Windows	PicoScope 6 is your complete test and measurement lab in one application. Features include: Capture modes: oscilloscope, spectrum and persistence. Channel maths: calculate the sum, difference, product, inverse or create your own custom function using standard arithmetic, exponential and trigonometric functions. Mask limiting testing: pass/fail, failure count, total count. Serial Decoding: decode data from serial buses such as DCC, LIN and UART/RS-232. Automated measurements Scope mode: AC RMS, true RMS, cycle time, DC average, duty cycle, falling rate, fall time, frequency, high pulse width, low pulse width, maximum, minimum, peak–to–peak, rise time and rising rate. Spectrum mode: frequency at peak, amplitude at peak, average amplitude at peak, total power, total harmonic distortion (THD % and THD dB), total harmonic distortion plus noise (THD+N), spurious-free dynamic range (SFDR), signal+noise+distortion to signal+noise ratio (SINAD), signal to noise ratio (SNR) and intermodulation distortion (IMD). Export data formats: comma separated values (CSV), tab delimited (TXT), Windows bitmap (BMP), graphics interchange format (GIF), portable network graphics (PNG), MATLAB 4 format (MAT). Operating systems supported: Microsoft Windows 7, 8 and 10*
