User Manual 1177.6298.02 ─ 08
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
ESW 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
ESW 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.

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
ESW is sufficient to
run an existing GPIB program without adaptation.
