13 Bias Tees
or
RFFE -
GPIO
Interface
This slot can be equipped with one of the following options:
●
R&S ZNB-B1, "Bias Tees", providing two or four additional BNC inputs labeled
BIAS 1 ... 4 (for two-port or four-port analyzers). The inputs can be used to
apply an external DC voltage (bias) to the test ports. For fuse replacement,
refer to Chapter 7.3, "Replacing Fuses", on page 77.
●
R&S ZN-B15 "RFFE - GPIO Interface".
25-pin female connector, providing:
– 2 independent RF Front-End (RFFE) interfaces according to the MIPI® Alli-
ance "System Power Management Interface Specification".
– 10 General Purpose Input/Output (GPIO) pins.
14 Device
Control
Option R&S ZNB-B12 "Device Control" provides a PCIe and a Direct Control con-
nector.
The Direct Control interface enables direct connections between the VNA measure-
ment bus and one or more extension devices, such as:
●
An external RFFE GPIO interface R&S ZN-Z15.
●
Switch matrices R&S ZN-Z8x.
●
Multiport calibration units R&S ZN-Z154.
15 Handler
I/O
Option R&S ZN-B14, Handler I/O (Universal Interface), providing a Centronics 36
input/output connector.
16 GPIB Option R&S ZNB-B10 provides a GPIB bus connector according to standard IEEE
488 / IEC 625.
17 DC INPUT Option R&S ZNB-B81"DC Inputs" provides four BNC inputs for DC measurements
(adjustable to different voltage ranges).
Input levels, EMC
The maximum input levels and voltages of the input connectors at the front and rear
panel must not be exceeded. Match signals with 50 Ω to comply with EMC directives.
