SCPI Output Format
The HP ESA analyzers return data in NR3 format as described in IEEE Std 488.2-1992. Response
terminators may be different than HP 8590-Series analyzer terminators. For example, note the following
differences:
• non-block response termination in the HP 8590-Series analyzers is <CR><LF>, but in the HP ESA
analyzers it is <LF><-EOI>
• boolean queries in HP 8590-Series analyzers return ON or OFF, whereas boolean queries in HP ESA
analyzers return 1 or 0
• OA and EP are valid parameters for many HP 8590-Series spectrum analyzer commands, but are not
valid for HP ESA spectrum analyzer commands
