Stop frequency
The stop frequency given in the table may be limited to the corresponding frequency
range of the R&S
FPL1000.
Command LF sets the stop frequency for 8566A/B to a maximum value of 2 GHz.
Test points (trace points)
The number of trace points is switched over only upon transition to the REMOTE state.

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 accordingly in the remote-control pro-
grams for instruments of this series.
Therefore, in response to a query, the R&S
FPL1000 returns data of the same struc-
ture 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 (com-
mand O1) and physical values (command O2, O3 or TDF P). As to the "Display Units"
format, the level data of the R&S
FPL1000 is converted to match the value range and
the resolution of the 8566/8568 series. Upon transition to the
REMOTE
state, the
R&S
FPL1000 is reconfigured such that the number of test points (trace points) corre-
sponds to that of the 85xx families (1001 for 8566A/B and 8568A/B, 601 for 8560E to
8565E, 401 for 8594E).
10.11.2.6
Trace Data Output Formats
All formats are supported for trace data output: display units (command O1), display
units in two byte binary data (command O2 or TDF B and MDS W), display units in one
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).
