VNA command reference
This chapter describes the SCPI commands implemented by the VNA mode of the
R&S
ZNL/ZNLE.
Compatibility with R&S ZVB and older instruments
The SCPI command set for the R&S
ZNL/ZNLE vector network analyzer has been
designed for compatibility with network analyzers R&S ZVA and R&S ZVB. A special
subset of commands has been implemented for compatibility with older analyzers of
the R&S ZVR family. These commands are listed in
Chapter 11.5.3, "R&S ZVR/ZVABT

ZNL/ZNLE features but do not need R&S ZVR
compatibility, you should use the commands listed in
