11.18.3 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

<SPC> = 32

<ETX> = 3

Command sections given in [ ] are optional.

The R&S ESR GPIB hardware differs from that used in the HP analyzers. Therefore,

the following constraint 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.
