Model-Dependent Default Settings

If the GPIB language is switched over to an 85xx model, the GPIB address will automatically be switched
over to 18 provided that the default address of the R&S FSP (20) is still set. If a different value is set, this
value will be maintained. Upon return to SCPI, this address will remain unchanged.
The following table shows the default settings obtained after a change of the GPIB language and for the
commands IP, KST and RESET:

Data Output Formats

In the case of the SCPI and IEEE488.2 standards, the output formats for numerical data are flexible to a
large extent. The output format for the HP units, by contrast, is accurately defined with respect to the
number of digits. The memory areas for reading instrument data have therefore been adapted accord-
ingly in the remote-control programs for instruments of this series.
Therefore, in response to a query, the R&S FSP returns data of the same structure as that used by the
original instruments; this applies in particular to the number of characters returned.
Two formats are currently supported when trace data is output: Display Units (command O1) and physi-
cal values (command O2, O3 or TDF P). As to the "Display Units" format, the level data of the R&S FSP
is converted to match the value range and the resolution of the 8566/8568 series. Upon transition to the

The stop frequency given in the table may be limited to the corresponding

Command LF sets the stop frequency for 8566A/B to a maximum value of 2
GHz.
The number of trace points is switched over only upon transition to the REMOTE
state.
