i am using network analyzer to obtain open loop transfer function. I am adding perturbation through ADC. my question is do adding though software add delay in the transfer function ? since it is open loop so why it would add a delay in the final model ?

Greetings! I'm working on a project using the Analog Discovery 2. I observed that the Pattern Generator can be used as a Transmitter and the Logic Analyzer can be used as a Receiver, if used properly. Here's the VB Script that I've been working on: AD2_Time_Testing.rar The VB Script does the following: 1). ASCII data is entered. 2). The algorithm in the code will convert it into binary to be transmitted by the Pattern Generator. 3). The Logic Analyzer will receive the bits in Record Mode. 4). The UART decoder algorithm will convert the bits received back into ASCII character. The result that I'm expecting is this: "U" ---> (Converted into Binary) ---> (Transmitted by the Pattern Generator) --> (Bits received in Record Mode) --->(BIts will be converted back in ASCII) ---> "U" The actual result that I'm getting is this: (DIO#0 (Tx) and DIO#2 (Rx) was used) Data that is to be transmitted: I connected DIO #0 to DIO #2 and a UART controller. Data was sucessfully transmitted and it was received by the UART controller: I also observed the bits returned by the FDwfDigitalInStatusData became like this: I think because of this change the UART Decoder algorithm cannot process it properly. That's why I'm getting this result: The output of DIO0Mesg should be "U" as well. Any advice regarding this? Best regards, Lesiastas AD2_Time_Testing.rar

How to read a CSV file in script editor and plot in wavegenerator ?

Greetings, I am creating a VBA program which uses the DigitalOut Functions in the dwf.vb file to replicate the capability of the AD2's Pattern Generator. I'm having trouble of declaring the FDwfDigitalOutDataSet API in VBA. I always encounter this error: I am aware that this is because of some data types in VB6 that are not supported in VBA. I've encountered similar errors in the FDwfDigitalOutRepeatSet and the FDwfDigitalOutDividerSet API. What I did was change the UInteger data type to Integer, since its the data type supported supported in VBA. Function FDwfDigitalOutRepeatSet(ByVal hdwf As Integer, ByVal cRepeat As Integer) As Integer End Function Function FDwfDigitalOutDividerSet(ByVal hdwf As Integer, ByVal idxChannel As Integer, ByVal v As Integer) As Integer End Function I already changed countOfBits in FDwfDigitalOutDataSet from UInteger to Integer, but the error is still present. I think the error is because of the <MarshalAs(UnmanagedType.LPArray)> used in the FDwfDigitalOutDataSet. What changes could I do to FDwfDigitalOutDataSet in order to agree with VBA? Function FDwfDigitalOutDataSet(ByVal hdwf As Integer, ByVal idxChannel As Integer, <MarshalAs(UnmanagedType.LPArray)> rgBits() As Byte, ByVal countOfBits As Integer) As Integer End Function Sorry in advance, but I could be wrong since I'm a complete novice in coding, especially across different programming platforms. Any advice on how to work around this? Regards, Lesiastas

New to electronics and the Discovery 2--Since the AWG leads do not pass through the BNC Adapter board, can I just use one of my scope probes on the 1X setting as a test lead? Anything I need to be careful of when doing so?
