Considerations for test setup
Cable selection and electromagnetic interference (EMI)
Electromagnetic interference (EMI) can affect the measurement results.
To suppress electromagnetic radiation during operation:
●
Use high-quality shielded cables, for example, double-shielded RF and LAN
cables.
●
Always terminate open cable ends.
●
Ensure that connected external devices comply with EMC regulations.
Regarding cable length and quality, the following requirements have to be met:
Table 3-1: Cable Requirements
Cable Type (Connector)

Standard cables, length ≤ 3m
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 devices.
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.
