R&S ESU Remote Control – Description of Commands
GPIB Commands of HP Models 856xE, 8566A/B, 8568A/B and 8594E
6.288 Operating Manual 1302.6163.12 - 03
6.23.8 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 will be converted into value range and resolution of the 8566/8568 models. On transition to
REMOTE state the number of trace points will be 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).
6.23.9 Trace Data Input Formats
Trace data input is only supported for binary date (TDF B, TDF A, TDF I, MDS W, MDS B).
6.23.10 GPIB Status Reporting
The STB command and the serial poll respond with an 8-bit value having the following assignment:
Bits 0 and 7 are not used and always have the value 0.
Please note that the R&S ESU 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 analyzers this bit mon-
itors the state of the SRQ line on the bus. On the R&S ESU 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.
