CONTrol<Ch>:RFFE:TEST:SENSe:TRIGger
Starts the voltage/current measurements on all RFFE pins.
The measurement time can be defined using CONTrol<Ch>:RFFE:TEST:TIME.
Suffix:
<Ch>
.
Channel number
This suffix is ignored and can be omitted.
Usage: Event
Options: R&S ZN-B15/Z15 Var. 03
Manual operation: See "Start Meas" on page 607
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 605
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.
