R&S ESU Remote Control – Description of Commands
GPIB Commands of HP Models 856xE, 8566A/B, 8568A/B and 8594E
1) HP 8594E only
2) Command will be accepted without error message, but will be ignored
6.23.3 Special Features of the Syntax Parsing Algorithms for 8566A and
8568A Models
The command syntax is very different for models A and B. Different names are assigned to identical
instrument functions, and the command structure likewise differs considerably between models A and
models B.
The command structure for models A is as follows:
<command> ::=
<command code>[<SPC>][<data>|<step>][<SPC>][<delimiter>][<command code>]...<delimiter>
<data> ::= <value>[<SPC>][<units code>][<SPC>][<delimiter>][<SPC>][<data>]...
<step> ::= UP|DN
where
<command code> = see Table "Supported Commands"
<value> = integer or floating-point numerical value
<units code> = DM | -DM | DB | HZ | KZ | MZ | GZ | MV | UV | SC | MS | US
<delimiter> = <CR> | <LF> | <,> | <;> | <ETX>
<SPC> = 32
10
<ETX> = 3
10
Command sections given in [ ] are optional.
The R&S ESU GPIB hardware differs from that used in the HP analyzers. Therefore, the following con-
straint exists:
<LF>| <EOI> are still used as delimiters since the GPIB hardware is able to identify them. The other
delimiters are identified and evaluated during syntax analysis.
