Software
PicoLog PicoLog software is a powerful yet flexible program for collecting, analysing and displaying data. 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
PicoScope 6 PicoScope 6 is your complete test and measurement lab in one application. Features include:
Capture modes - oscilloscope, spectrum and persistence modes
Channel maths - calculate the sum, difference, product, inverse or create your own custom function using
standard arithmetic, exponential and trigonometric functions
Automated measurements:
Scope mode: AC 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, total power, total harmonic distortion (THD), 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)
Software development kit A growing collection of drivers and example code for various programming languages including: C, C++, Excel
and LabVIEW.
