Using the DC power supply (option R&S
FSV
‑
B30), the instrument can be oper-
ated with a DC voltage of 10
V to 28
V. The voltage source can have a current of
25
A to 12.5
A.
If you use an external power supply unit to supply safety extra-low DC voltage
(SELV) to the instrument, be sure to meet the requirements for reinforced/double
insulation in accordance with DIN/EN/IEC 61010 (UL 3111, CSA C22.2 No.
1010.1) or DIN/EN/IEC 60950 (UL 1950, CSA C22.2 No. 950). Provide current
limitation in accordance with DIN EN 61010-1 Appendix F2.1. Use a cable no lon-
ger than 3
m.
