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
ESR returns data of the same structure as
that used by the original instruments; this applies in particular to the number of charac-
ters 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
ESR is converted to match the value range and the
resolution of the 8566/8568 series. Upon transition to the
REMOTE
state, the
R&S
ESR 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).
11.18.7
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).
11.18.8
Trace Data Input Formats
Trace data input is only supported for binary date (TDF B, TDF A, TDF I, MDS W, MDS
B).

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:
