A.2 Basic Operation
This chapter describes the use of an R&S ZVA vector network analyzer and two
frequency converters R&S ZCxxx for 2-port transmission measurements.
Measurements using other converters of the R&S ZCxxx family are performed in
an analogous way.
A.2.1 Required equipment
Measurements with frequency converters can be carried out with the following
equipment:
●
n frequency converters for an n-port measurement
●
Vector network analyzer (VNA) R&S ZVA or R&S ZVT with an upper fre-
quency limit of 20 GHz or higher (R&S ZVT20, R&S ZVA24, R&S ZVA40 ...).
The network analyzer must provide one test port for each converter. In addi-
tion, a common LO signal must be applied to all converters. For R&S
ZVT20
with at least 4 ports, R&S ZVA24 var.26, R&S ZVA40 var. 42 and R&S ZVA50
var. 52 the LO can be supplied by two different test ports that are fed by the
same internal source. If the VNA is a four-source model R&S
ZVA24 var. 28,
R&S ZVA40 var. 48 or R&S ZVA67, the signal must be supplied by a single
port and split by an external power splitter. For the R&S ZVA67, a mm-wave
adapter kit (order number 1323.7746.00) is available which includes the
power splitter and all necessary adapters.
The required adapters and splitters are offered as complementary adaption
kits (see
Chapter A.1.4, "Adaption Kits R&S ZCAK" , on page 41).
