Example:
See
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
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
. 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.
