Initial Program Considerations

Programs should begin with a series of HP BASIC statements and

signal analyzer commands that form a good starting point for

measurements. Some initial program considerations are discussed

CLEAR is an HP BASIC statement that puts a GPIB instrument (for

example, 8560E) in a known state (the preset state) by clearing the

input buffer, the output buffer, and the command parser of the speciﬁed

instrument so that it is ready for operation. This command can be used

to clear devices on the bus singly or in unison. It is often desirable to

clear only one instrument so that other instruments on the bus are not

affected. Refer to the "Program Timing" section, in this chapter, for

more information.

To clear only the spectrum analyzer, CLEAR 718 should be used.

To clear all devices at select code 7, CLEAR 7 must be used.

IP, the instrument preset command, presets all parameters of the

spectrum analyzer for the current mode of operation, and provides a

good starting point for all measurement processes. Executing IP is

actually the same as executing a number of commands that set the

spectrum analyzer to a known state (the preset state). Refer to Table

4-8 for more information about the preset state.
