    * - Parameter
      - Value

    * - Nominal voltage
      - 100 - 240 V AC (± 10 %)

    * - Frequency
      - 47-63 Hz

    * - Power
      - max. 60 W

The maximum voltage and current ratings of the signal inputs and outputs
are specified on the |product|'s housing and must not be exceeded. 
The details on the characteristics of the input channels can be found in the dedicated section :ref:`input-channels`.


Equipment installation
==================================

The |product| does not require assembly and is supplied fully assembled.
It can be installed as a table top instrument or in a standardized 19-inch rack.
Any operating position shall provide adequate space for cable connections and air circulation.

A table top installation requires an even and horizontal surface with enough space for easy access to the device.

Installation in a standardized 19-inch rack requires 2 height units. The rack shall provide sufficient ventilation
and must not obstruct the ventilation openings of the |product|'s rear panel.

Position the |product| in a manner that allows the user to disconnect
the device from the mains at any time and without restrictions.

Before connecting to the mains, inspect the product and the power cord for visible damage.
Connection to the mains shall be done only with the supplied detachable power cord.

        | - in case of ingress of any liquids inside the product's housing.

The |product| provides one functional ground terminal on the rear panel located next to the power cord receptacle.
All connectors that feature ground terminals are electrically connected to the |product| housing and to the functional ground terminal.
This includes shield terminals on the SMA connectors and the USB-C connector.

Take care of appropriate grounding practices and ensure that all connected accessory and equipment shares common ground with the |product|.
Connection of additional accessories or equipment that are grounded to an independent grounding circuit has the potential risk of electrical shock.
An inappropriately grounded |product| and/or connected equipment may result in product damage, malfunction, degraded performance or poor signal quality.
