Index Label Description
13 Bias Tees
or
RFFE -
GPIO
Interface
This slot can be equipped with one of the following options:
●
"Bias Tees", providing two or four additional BNC inputs labeled PORT BIAS
1 ... 4 (for two-port or four-port analyzers). The inputs can be used to apply
external DC voltages (biases) to the test ports.
–
Not available for 2nd generation R&S ZNB20 and for 1st generation
R&S ZNB40 that are equipped with the new reflectometer board (order no.
1317.8015.03)
– Optional for R&S ZNB4|8
– Always equipped for other R&S ZNB models
See Chapter 4.7.13, "Bias tees (R&S ZNB only)" , on page 254.
Note that there is no additional HW or SW switch for the bias tees, i.e. the volt-
age is applied to the RF port as soon as you connect the voltage source to the
corresponding PORT BIAS connector.
For fuse replacement, refer to
Chapter 11.1, "Replacing fuses" , on page 1535.
●
R&S ZN-B15 "RFFE - GPIO Interface" ( 1st generation R&S ZNB only )
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.
See Chapter 4.7.19, "RFFE GPIO interface" , on page 257.
14 Device
Control Option R&S ZNB-B12 "Device Control" provides a PCIe and a Direct Control con-
nector.
See Chapter 4.7.17, "Device control" , on page 256.
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.
See Chapter 4.7.19, "RFFE GPIO interface" , on page 257.
●
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.
See Chapter 4.7.18, "Handler I/O (universal interface)" , on page 256.
16 GPIB Option R&S ZNB-B10 provides a GPIB bus connector according to standard IEEE
488 / IEC 625.
See Chapter 12.3.3, "GPIB interface" , on page 1541.
17 DC INPUT Option R&S ZNB-B81"DC Inputs" provides four BNC inputs for DC measurements
(adjustable to different voltage ranges).
See Chapter 5.2.11, "DC tab" , on page 314.
Match signals with 50 Ω to comply with EMC directives. See also Chapter 3.1.5, "Con-
siderations for test setup" , on page 26.
