4.7.19 RFFE GPIO interface
Internal: Option R&S ZN-B15 (1st generation R&S ZNB only)
External: Option R&S ZN-Z15
The trend in mobile radio communication is towards higher scale of integration of exter-
nal components such as filters, switches, low noise and power amplifiers. The require-
ment for test and measurement equipment is to make it possible to control those com-
ponents directly from the instrument without the need of additional external tools, e.g. a
USB to RFFE adapter.
For these kinds of applications, Rohde & Schwarz has developed an RFFE-GPIO
extension board for the R&S
ZNB/ZNBT. This board is equipped with a 25-pin female
connector interface providing 2 independent RF Front-End (RFFE) interfaces accord-
ing to the MIPI® Alliance "System Power Management Interface Specification" and 10
General Purpose Input/Output (GPIO) pins. RFFE command execution and GPIO volt-
age settings can be synchronized with the sweep (sweep sequencer functionality);
however, RFFE read is not supported in sweep sequencer mode.
Versions and variants
The following variants of the RFFE-GPIO extension board are available:
●
R&S ZN-B15 variant 02 , order number 1323.9355. 02
●
R&S ZN-B15 variant 03 , order number 1323.9355. 03 , including current and voltage
measurements for all RFFE and GPIO pins
●
R&S ZN-Z15 variant 02 , order number 1325.5905. 02 , the external version of
R&S ZN-B15 variant 02
●
R&S ZN-Z15 variant 03 , order number 1325.5905. 03 , the external version of
R&S ZN-B15 variant 03
Information about the voltage and current levels is available in Chapter 12.3.5, "RFFE -
GPIO interface" , on page 1552.
●
For a 2nd generation R&S ZNB (order nos. 1334.3330.xx) and the R&S ZNBT, only
the external versions R&S ZN- Z 15 can be used.
●
Currently, the external versions have to be connected via Direct Control, which in
turn requires
Device control option R&S ZNB/ZNBT-B12.
●
No matter if connected internally or externally, there is no need to perform any kind
of calibration or alignment of the extension board. The analyzer firmware automati-
cally detects and supports it. The controlled devices can be hot-plugged.
●
The analyzer firmware only supports a single RFFE GPIO interface board.
