ESA/PSA Programming Examples

Using Visual Basic

6 to Capture a Screen

Image

This is a Visual Basic example that stores the current screen image on

your PC. The program works with the ESA or PSA Series spectrum

analyzers. The bas file (screen.bas) and a compiled executable

(screen.exe) can be found on the Documentation CD.

This example:

1. Stores the current screen image on the instrument’s flash as

C:PICTURE.GIF.

2. Transfers the image over GPIB or LAN and stores it on your PC in

the current directory as picture.gif.

3. The file C:PICTURE.GIF is then deleted from the instrument’s

flash.

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