Outside the R&S ZNL, batteries can be charged using the external battery charger
R&S FSV-B34. Even during battery operation, you can exchange the internal batteries
while the R&S ZNL is running, as long as one battery remains in the instrument. How-
ever, it is not recommended to operate the R&S ZNL with only one battery for a longer
period.
This option is not available for the R&S ZNLE.
For models R&S ZNL14 and R&S ZNL20, hot-swapping a single Li-ion battery is possi-
ble. However, long-term operation with a single battery is not supported.
