Signal input and output levels
Information on signal levels is provided in the data sheet. Keep the signal levels
within the specified ranges to avoid damage to the product and connected devi-
ces.
If you use an external power amplifier, make sure that the maximum RF
input power of the calibration unit quoted in the data sheet is never excee-
ded. See
Preventing electrostatic discharge (ESD)
Electrostatic discharge is most likely to occur when you connect or disconnect a
DUT.
►
NOTICE!
Risk of electrostatic discharge. Electrostatic discharge can damage
the electronic components of the product and the device under test (DUT).

USB connection
The calibration unit is equipped with a USB Type-C connector at the rear. The
USB connection is used to power-supply and control the unit from a network ana-
lyzer of the R&S ZVx or R&S ZNx family.
A direct USB connection is recommended. You can connect several calibration
units to different USB ports of the analyzer and you can connect other USB devi-
ces (mouse, keyboard, memory stick etc.) simultaneously.
In general, an unused calibration unit can remain connected to the USB port of
the analyzer and you can connect or disconnect it while the network analyzer is
operating. However, note the following restrictions.
