ESA/PSA Programming Examples

Using Visual Basic

6 to Transfer Binary Trace

Data

This is a Visual Basic example that gets binary trace data from the

instrument. Binary data transfers are faster than the default ASCII

transfer mode, because less data is sent over the bus. This example

works with the ESA or PSA Series spectrum analyzers. The bas file

(bintrace.bas) and a compiled executable (bintrace.exe) can be found on

the Documentation CD.

This example:

1. Queries the IDN (identification) string from the instrument.

2. While in Spectrum Analysis mode, it reads the trace data in binary

format (Real,32 or Real,64 or Int,32).

3. Stores the data is then to a file "bintrace.txt".

NOTE This example uses GPIB address 18 for the spectrum analyzer.
