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
GPIO
For a 2nd generation R&S ZNB (order nos. 1334.3330.xx) and the R&S ZNBT, only
the external versions R&S ZN-Z15 can be used.
Currently, the external versions have to be connected via Direct Control, which in
turn requires
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.
