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

<ETX>
= 3

Command sections given in [ ] are optional.
The R&S
FPL1000 GPIB hardware differs from that used in the HP analyzers. There-
fore, 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.

Special Behavior of Commands
Command
Known Differences
ABORT
Does not automatically set the command complete bit (bit 4) in the status byte. An addi-
tional DONE is required for that purpose.
ANNOT
Only frequency axis annotation is affected.
AT
AT DN/UP: Step size
CAL
The CAL commands do not automatically set the command complete bit (bit 4) in the sta-
tus byte. An additional DONE command is required for that purpose.
CF
Default value, range, step size
CR
Default ratio Span/RBW
CT
Formula for coupled sweep time
CV
Default ratio RBW/VBW
DET
DET? returns SAMP instead of SMP on the R&S
FPL1000.
DET not automatically set the command complete bit (bit 4) in the status byte. An addi-
tional DONE is required for that purpose.
ERR?
Deletes the error bit in the status register but always returns a '0' in response.
