HP3458A Emulation Mode
H-2
Command syntax and compatibility
The following paragraphs discuss certain command syntax
and compatibility issues that apply to the HP3458A emula-
tion mode.
Parameter defaults
The Model 2002 will assume default parameters if the
parameters are omitted. Default parameters assigned a value
of -1. Sequential commas or omission of the first parameter,
however, are not supported.
Examples: FUNC Supported
FUNC ACV Supported
FUNC ACV,-1,-1 Not Supported
FUNC, , AUTO Not Supported
FUNC ACV,, Not Supported
Delimiting parameters
The Model 2002 supports an undocumented feature of the
HP3458A, which allows parameters to be separated by either
spaces or commas.

return a “Function not supported” error.

The HP3458A emulation mode supports the short forms of
the following FUNC commands:

as sending the FUNC command, but with FUNC omitted.
