PS2000Constants.m

%% PS2000Constants 
%
% The PS2000Constants class defines a number of constant values that
% can be used to define the properties of an Oscilloscopes device or
% for passing as parameters to function calls.
%
% The properties in this file are divided into the following
% sub-sections:
% 
% * Timebases
% * ETS Mode Properties
% * Analogue offset values
% * Maximum/Minimum Waveform Frequencies
% * Function/Arbitrary Waveform Parameters
% * Maximum and minimum ADC count values
% * PicoScope 2000 Series Models using this driver
%
% Ensure that the location of this class file is on the MATLAB Path.
