How to use NIScope in Matlab

According to Adnan,you should install NI-Scope software v3.4,all later versions are not compatible with MATLAB.But I’m not sure with this because my MATLAB is the latest2013b version and has a NI Scope hardware support package:Install NI Scope MATLAB support package:HOME>Add-Ons>Get hardware support package>'Install NI Scope support package'(hardware support package is only available in MATLAB2013b)After you have installed the support package or NI-Scope software v3.4,set up complier:>>mex-setupConvert driver to MATLAB instrument driver format>>makemid('niscope')Now you can control NIScope device using Matlab,to know the specific function of the NIScope device,use Matlab Instrument Driver Editor:>>mideditopen niscope.mdd,niscope.mdd is the converted driver file,should found in current directory.In Groups you should find all the functions of the driver.Bellow is a example for you to understand how it works:Connect a voltage signal to CH1and a trigger signal to PFI,run the following scrip and you should get the voltage signal.Note:'DAQ::Dev1'is the source name of the digitizer,it can be found in NI MAX.%Signal channel：CH0%Trig channel：PFI1%sample rate（Hz）SampleRate=50e6;%per B-5132Max:50e6%Time span of signal to getTimeSpan=0.1;%secondsVerticalRange_CH0=4;%USB-5132Vpp:0.04/0.1/0.2/0.4/1/2/4/10/20/40%VerticalRange_CH1=4;Offset_CH0=0;%Offset_CH1=0;%%TimeOut=30;%seconds,0:Inf%ChannelList='0,1';ChannelList='0';NSamples=int32(SampleRate*TimeSpan);%WaveformArray=zeros(1,2*NSamples);%WfmInfo=[struct struct];WaveformArray=zeros(1,NSamples);WfmInfo=[struct];t=double(0:NSamples-1)/SampleRate*1e6;%muS;%%%Impedance:50/1000000(in unit of ohm)%Slope:0/1falling/Rising edge%TriggerCoupling0/1AC/DC%Channel source/Channel list:'0','1','0,1','VAL_PFI_1'niScopeObj=icdevice('niscope.mdd','DAQ::Dev1','optionstring','simulate=false');connect(niScopeObj);%Configure measurement type%0/1normal/dynamic sampling rateconfiguration=get(niScopeObj,'configuration');invoke(configuration,'configureacquisition',0);%Configure vertical settings:%Configurationfunctionsvertical=get(niScopeObj,'Configurationfunctionsvertical');%invoke(Configurationfunctionsvertical,'configurevertical',...%ChannelList,Range,Offset,Coupling,ProbeAttenuation,Enabled); Configurationfunctionsvertical=get(niScopeObj,'Configurationfunctionsvertical');invoke(Configurationfunctionsvertical,'configurevertical',...'0',VerticalRange_CH0,Offset_CH0,1,1,1);%Configurationfunctionsvertical=get(niScopeObj,'Configurationfunctionsvertical');%invoke(Configurationfunctionsvertical,'configurevertical',...%'1',VerticalRange_CH1,Offset_CH1,1,1,1);%Configure horizontal settings:%Configurationfunctionshorizontal=get(niScopeObj,'Configurationfunctionshorizontal');%invoke(Configurationfunctionshorizontal,'configurehorizontaltiming',...%MinSampleRate,MinNumPts,RefPosition,NumRecords,EnforceRealtime);%USB-5132dose not support multirecords acquisition,NumRecords=1always.
