Trace Data Input Formats
Trace data input is only supported for binary date (TDF B, TDF A, TDF I, MDS W, MDS
B).
10.11.2.8
GPIB Status Reporting
The assignment of status bits by commands R1, R2, R3, R4, RQS is supported.
The STB command and the serial poll respond with an 8-bit value with the following
assignment:
Bit enabled by RQS
Description
0
not used (value 0)
1
Units key pressed
2
End of Sweep
3
Device Error
4
Command Complete
5
Illegal Command
6
Service Request
7
not used (value 0)
Bits 0 and 7 are not used and always have the value 0.
Please note that the R&S
FPL1000 reports any key pressed on the front panel rather
than only the unit keys if bit 1 was enabled.
Another difference is the behavior of bit 6 when using the STB? query. On the HP ana-
lyzers this bit monitors the state of the SRQ line on the bus. On the R&S
FPL1000 this
is not possible. Therefore this bit is set, as soon as one of the bits 1 to 5 is set. It won't
be reset by performing a serial poll.

Reference: Command Set of Emulated CXA/EXA Models
The R&S
FPL1000 analyzer family supports a subset of the GPIB commands of
CXA/EXA instruments.
Despite the differences in system architecture and device features, the supported com-
mands have been implemented in a way to ensure a sufficiently high degree of corre-
spondence with the original.
In many cases the selection of commands supported by the R&S
FPL1000 is sufficient
to run an existing GPIB program without adaptation.
