ESG Family Signal Generators Softkey/Command Cross-Reference
Agilent 8656/57-Compatible Language
Command Mapping
The SCPI command, :SYSTem:LANGuage “SCPI”|“COMP”|“NADC”|“PDC”|“PHS”, lets
you set the signal generator remote (GPIB) language to one of the following choices:
• “SCPI” - Default language (Standard Commands for Programmable Instruments)
• “COMP” - 8656B, 8657A/B compatibility
• “NADC” - 8657D NADC compatibility
• “PDC” - 8657D PDC compatibility
• “PHS” - 8657J PHS compatibility
When you operate in an 8656/57-compatibility language, internal mapping occurs in the
signal generator to effect an equivalent SCPI response. In addition, the modulation
sources for the 8656/57 are not the same as for the ESG family, so when you operate in an
8656/57-compatibility language, the following mapping occurs for selecting AM and FM
sources:
The 8656/57 Signal Generators allow multiple modulations to use the same input, the ESG
Family Signal Generators do not. If you configure multiple modulations on the same input,
the signal generator will respond by automatically disabling modulations.
The mapping between the 8656/57-compatible commands and the SCPI commands will
change depending on the other parameters that are executed. Refer to the following
explanations of the commands:
