SWEep – every time a sweep is complete
CHANnel – when all the sweeps for each channel are complete
GLOBal – when all sweeps in all channels are complete
Note:*RST or "Preset" do not change the configuration of the
Universal Interface. Use CONTrol:HANDler:RESet to restore
default values.
*RST: n/a (default: GLOBal)
Example: See CONTrol:HANDler:PASSfail:MODE
CONTrol<Ch>:RFFE<Bus>:COMMand:DATA
<Command>
Defines an RFFE command for channel <Ch> and RFFE bus interface <Bus>, which
can be executed using CONTrol<Ch>:RFFE<Bus>:COMMand:SEND (write-only) or
CONTrol<Ch>:RFFE<Bus>:COMMand:SEND? <BytesToRead> (with read-back).
For details and background information see the "MIPI Alliance Specification for RF
Front-End Control Interface".
Suffix:
<Ch>
.
Channel number
<Bus> RFFE bus interface number
Parameters:
<Command> 3, 5, ..., 35, or 37 hexadecimal digits (0-F), defining the com-
mand to be executed:
- digit 1 is the slave address,
- digits 2 and 3 specify the command number and
- the remaining digits represent the data part with up to 17 bytes
(0, 2, ..., 32, or 34 hex digits).
Manual operation: See "RFFE Command" on page 553
CONTrol<Ch>:RFFE<Bus>:COMMand:SEND
CONTrol<Ch>:RFFE<Bus>:COMMand:SEND? <BytesToRead>
Sends the RFFE command for channel <Ch> and RFFE bus interface <Bus>.
In its "set" form, it is a pure write command. In its query form, the command attempts to
read <BytesToRead> bytes back: the result is returned in the form
<ParityBit>,<ReadError>,'<result>', where
●
<ReadError>==1 indicates a parity mismatch
●
<result> consits of 2·<BytesToRead> hexadecimal digits.
The command has to be defined previously using CONTrol<Ch>:RFFE<Bus>:
COMMand:DATA. On a R&S ZN-B15/Z15 var. 03, before the command is executed the
related shunt resistance is set to its minimum possible value.
For details and background information see the "MIPI Alliance Specification for RF
Front-End Control Interface".
