byte binary data (command O4 or TDF B and MDS B) and physical values (commands
O3 or TDF P). With format "display units" the level data is converted into value range
and resolution of the 8566/8568 models. On transition to REMOTE state the number of
trace points are reconfigured in order to be conform to the selected instrument model
(1001 for 8566A/B and 8568 A/B, 601 for 8560E to 8565E, 401 for 8594E).

Trace Data Input Formats
Trace data input is only supported for binary date (TDF B, TDF A, TDF I, MDS W, MDS
B).
11.11.2.8
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.
