Flexible power supply, including an integrated rechargeable battery With an input voltage range of 110 V to 240 V, the R&S EPL1000 can be connected to all customary AC power sources. If an AC power source is not available, the integrable 12 V to 24 V DC input (R&S FPL1-B30) can be used as an alternative. And if no external power source is available, the R&S EPL1000 is still usable thanks to the integrated rechargeable battery (R&S FPL1-B31). For an especially long operating time, the batteries can be exchanged (R&S FPL1-Z4/R&S FSV-B34). This makes outdoor measurements far away from power sources easy (such as in-situ measurements).

In addition to the optional internal battery pack, spare batteries are available for the R&S EPL1000. The spare battery pack comprises two additional Li-ion batteries. Outside the R&S EPL1000, 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 EPL1000 is running, as long as one battery remains in the instrument. However, it is not recommended to operate the R&S EPL1000 with only one battery for a longer period.
