3 Required Equipment
The Leveling Tool is suitable for test systems consisting of a vector network analyzer
R&S
ZNA, R&S ZVA (including R&S ZVA110), orR&S ZVT, in combination with one or
more frequency converters R&S ZCxxx or R&S ZVA-Zxxx(E); see Chapter 3.3, "Fre-
quency Converters " , on page 9
3.1 Vector Network Analyzers R&S ZNA
Up to n converters can be operated with an n-port instrument. However, with n con-
verter ports, the LO signal for the converters must be provided either by the optional
LO Out of the R&S
ZNA (R&S ZNA-B8) or by an external signal generator (see refer-
ence [ 1 ] in Chapter 10, "Additional Information" , on page 33 for details).
Supported firmware versions
The present version of the Leveling Tool requires a R&S ZNA with firmware version
1.90 or higher.
Free firmware updates are available for download on the R&S
ZNA product pages
( http://www.rohde-schwarz.com/product/zna ). Refer to the instrument's help system or
user manual for installation instructions.
Required Options
●
For two-port instruments, which can only have one internal source, the LO signal
for the converters must be provided via R&S
ZNA-B8 or an external generator. If
R&S ZNA-B8 is used, then option R&S ZNA-B26 is also required.
●
Option R&S ZNA-B26 "Direct IF Access" or R&S ZNAxx-B16, "Direct Generator/
Receiver Access" to connect the Meas and Ref ports of the converters.
●
Option R&S ZNA-K8, "Converter Control".
3.2 Vector Network Analyzers R&S ZVA and R&S ZVT
To drive one or more frequency converters, the R&S ZVA or R&S ZVT VNA must have
a maximum frequency
≥
20 GHz.
The four-port instruments R&S ZVA24/40/50/67 or an R&S ZVT20 with a minimum of
four ports provide the full functionality. It is also possible to operate the frequency con-
verters with R&S
ZVA24, R&S ZVA40, or R&S ZVA50 two-port instruments, but this
requires an additional external signal generator (see reference [1] in Chapter 10, "Addi-
tional Information" , on page 33 for details).
For R&S ZVA67 and other analyzers equipped with the latest synthesizer board Sy4G,
each test port is driven by its own, independent source. R&S ZVA67 two-port instru-
ments may be operated either with a single frequency converter or with two frequency
