Before Using the Examples

Before using the examples: On the signal generator select the following settings:

•Baud Rate - 9600 must match computer’s baud rate

•RS- 232 Echo - Off

The following sections contain HP Basic and C lines of programming removed from the programming interface examples in Chapter 3, Programming Examples,, these portions of programming demonstrate the important features to consider when developing programming for use with the RS- 232 interface.

NOTE For RS- 232 programming examples, refer to “RS- 232 Programming Interface Examples (ESG/PSG/E8663B Only)” on page 131.

Interface Check Using HP BASIC

This portion of the example program “Interface Check Using HP BASIC” on page 50, causes the signal generator to perform an instrument reset. The SCPI command *RST will place the signal generator into a pre- defined state.

The serial interface address for the signal generator in this example is 9. The serial port used is COM1 (Serial A on some computers). Refer to “Using RS- 232 (ESG, PSG, and E8663B Only)” on page 45 for more information.

The following program example is available on the signal generator’s Documentation CD- ROM as rs232ex1.txt. For the full text of this program, refer to “Interface Check Using HP BASIC” on page 131 or to the signal generator’s documentation CD- ROM.
