User Manual 1325.1268.02 ─ 04
The RF connections between analyzer and extension unit are established via the
Direct Access
connectors of the R&S
ZVA/ZVT (equipped with
B16
option). A com-
plete set of semirigid RF cables suitable for connecting a R&S
ZVA to a fully equipped
R&S
ZVAX-TRM in stacked
is provided with the R&S
ZVAX-
TRM; a cable set for operation in a 19'' rack - where instrument feet are omitted and
hence shorter cables are required - can be ordered separately (options
R&S
ZZA
‑
ZVAX).
For the R&S
ZVT equivalent cable sets are
not
available.
3.4.6 EMI Protective Measures
To avoid electromagnetic interference, the unit may only be operated when it is closed
and with all shielding covers fitted. Use only appropriate shielded signal and control
cables; see
Chapter 3.2.3, "RF Connectors"
on page 15. Observe the EMI classifica-
tions of both the R&S
ZVAX-TRM and the R&S
ZVA in their data sheets.
3.4.7 Connecting the Extension Unit to the AC Supply
The extension unit is automatically adapted to the AC supply voltage. The supply volt-
age must be in the range 100
V to 240
V; 50
Hz to 60
Hz and 400
Hz. The mains con-
nector is located at the rear panel.
► Connect the extension unit to the AC power source using the AC power cable
delivered with the unit.
The maximum and typical power consumption of the extension unit is listed in the data
sheet.
3.4.8 Power on and off
The mains connector and switch is located at the rear panel.
To turn the power on or off, press the AC power switch to position I
(On) or 0
(Off).
After power-on, the extension unit is in standby state.
