The Li-Ion battery pack and DC power connector are available as an optional accessory (R&S FPL1-B31 and R&S FPL1-B30).

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).
