EMI Suppression
To suppress electromagnetic interference (EMI), the instrument may be operated only
if it is closed and all covers are in place. The EMC class is listed on the data sheet.
The following conditions must be maintained to avoid interference:
●
Use suitable double-shielded cables that are no longer than 3 m.
●
Use only USB cables that are no longer than 1 m.
●
Use only USB devices that adhere to the permissible EMC values.
●
Terminate the outputs and cables with 50
Ω
.
●
Use only the cables R&S UP-Z2, R&S UP-Z3 and R&S UP-Z4 for the digital interfa-
ces.
●
Use the cable R&S UP-Z8A for the analog interface of option R&S UPP-B8, and
cable R&S UP-Z8D for the digital interface.
●
Use only doubled shielded CAT6 or CAT7 cables for the LAN interface.
2.3.2.1 Separate installation
The R&S UPP can be set up on a level surface in horizontal position and with unfolded
instrument feet.
Risk of injury with unfolded instrument feet
The instrument feet can suddenly fold back if the instrument is being moved or the feet
are not completely folded out. This can lead to personal injuries or damage to the
instrument.
Instrument stability, and thus safe operation, is only ensured when the instrument's feet
are completely folded out. Do not move the instrument and avoid performing work
under it when the feet are folded out. Secure the instruments from slipping (e.g. by
locking the instrument feet to the top of the front-panel frame).
If excessive loads are applied, the feet might break. The uniformly applied load to the
feet when folded out must not exceed 500
N (including the weight of the instrument
itself along with any equipment set on top of it).
