Getting Data from the Analyzer
T o get a data from the analyzer using the binary transfer method, the following procedure is
used:
1. Assign a binary data path. (Specifying format o.)
2. Specify the data transfer format as binary .
3. Dene a data array that is the same size as the data that will be retrieved.
4. Send the data query command.
5. Retrieve the data header .
6. Retrieve the data.
7. Retrieve the terminator .
8. Set the transfer format to ASCII mode if binary transfer is nished.
The binary data is sent in a mixed format of an ASCII header and a binary data body as shown
in Figure 3-4 and Figure 3-5. T o retrieve data correctly , you must retrieve the data header and
data itself independently .
The following is a sample module for receiving data using the IEEE 64-bit format:
ASSIGN @Dt TO 800;FORMAT OFF Binary path must turn o the formatting. Use 717 instead of 800
for the external controller .
OUTPUT @E5100;"FORM3" Specify the format as IEEE 64-bit format.
DIM Dat(1:201,1:2) A ssume that the receiving data size is 20122.
OUTPUT @E5100;"OUTPDATA?" Query the data trace array .
ENTER @E5100 USING "#,8A";Header$ Data header is 8 byte character .
ENTER @Dt;Dat(*) R eceiving data via binary path.
ENTER @E5100;End$ R eading terminator .
OUTPUT @E5100;"FORM4" Set ASCII mode if binary transfer is nished.
Module 3-8. Getting Data from Analyzer Using Binary Transfer
Note
Binary data transfer to the analyzer is not allowed. Use ASCII transfer for
sending data to the analyzer .
