1

Define an integer variable (bytesToSend) to store the number of bytes to send to the signal

 

generator.

 

 

2

Calculate the total number of bytes, and store the value in the integer variable defined in line 1.

 

 

3

Create a string large enough to hold the bytesToSend value as characters. In this code, string s

 

is set to 20 bytes (20 characters—one character equals one byte)

 

 

4

Create a string and set its length (cmd[200] ) to hold the SCPI command syntax and

 

parameters. In this code, we define the string length as 200 bytes (200 characters).

 

 

5

Store the value of bytesToSend in string s. For example, if bytesToSend = 2000; s = ”2000”.

 

sprintf() is a standard function in C++, which writes string data to a string variable.

 

 

6

Store the SCPI command syntax and parameters in the string cmd. The SCPI command prepares

 

the signal generator to accept the data.

 

strlen() is a standard function in C++, which returns length of a string.

 

If bytesToSend = 2000, then s = “2000”, strlen(s) = 4, so

 

cmd = :MEM:DATA ”BIN:FILE1\” #42000.

7Send the SCPI command stored in the string cmd to the signal generator contained in the variable id.

iwrite() is a SICL function in Agilent IO library, which writes the data (block data) specified in the string cmd to the signal generator.

The third argument of iwrite(), strlen(cmd), informs the signal generator of the number of bytes in the command string. The signal generator parses the string to determine the number of data bytes it expects to receive.

The fourth argument of iwrite(), 0, means there is no END of file indicator for the string. This lets the session remain open, so the program can download the user file data.
