Preventing electrostatic discharge (ESD)
Electrostatic discharge is most likely to occur when you connect or disconnect a DUT.
►
NOTICE! Electrostatic discharge can damage the electronic components of the
product and the device under test (DUT).
Ground yourself to prevent electrostatic discharge damage:
a) Use a wrist strap and cord to connect yourself to ground.
b) Use a conductive floor mat and heel strap combination.
During operation, if the firmware observes a serious unexpected disturbance (e.g. due
to ESD), it resets all hardware components to ensure proper instrument functioning. It
then restores the user settings to the state before the disturbance and indicates the
foregone hardware reset by an "Hardware communication problem [...]" information
popup.
3.1.6 Connecting the analyzer to the AC supply
For safety information, see "Connecting to power" on page 16.
The network analyzer is automatically adapted to the AC supply voltage, which must
be in the range of 100 V to 240 V at 50 Hz to 60 Hz. A line frequency of 400 Hz is also
supported.
The AC power connector is located in the upper part of the rear panel (see Chap-
ter 3.2.3, "Rear panel R&S ZNB", on page 47 or Chapter 3.2.4, "Rear panel
R&S ZNBT", on page 49).
1. Plug the AC power cable into the AC power connector on the rear panel of the
product. Only use the AC power cable delivered with the product.
2. Plug the AC power cable into a power outlet with ground contact.
The required ratings are listed next to the AC power connector and in the data
sheet.
3.
If necessary, also ground the product using the grounding terminal .
The maximum power consumption and the typical power consumption of the individual
analyzer models are listed in the data sheet.
The R&S ZNBT is protected by a fuse located below the AC power switch; see Chap-
ter 11.1, "Replacing fuses", on page 1535. There are no such fuses on the R&S ZNB.
