Key features

R&S

ZCxxx

Getting Started 1177.5156.02 ─ 05

The R&S

ZC90E is equipped with an electronic attenuator and a corre-

sponding control interface.

●

The R&S

ZVA supports this control interface via hardware option

R&S

ZVA-B8.

For a description of the corresponding connectors, their cabling and
operational aspects, see the Getting Started of the predecessor
R&S

ZVA-Z90E. It can be downloaded from the manual page of the

R&S

ZVA-Zxxx converter family (

R&S

ZNA and R&S

ZVT do not offer the external attenuator control

interface. With these analyzers, you can use the R&S

ZC90E like a reg-

ular R&S

ZC90, but with lower maximum output power and dynamic

range. See the data sheet of the R&S

ZCxxx family for details.
