●
"L POT" (low potential): signal input for parallel measurement (voltage measure-
ments).
●
"H CUR" (high current): signal input for series measurements (current measure-
ments).
●
"H POT" (high potential): signal input and output for parallel measurements (mea-
surement bridge).
Ground socket
Protective socket (4 mm banana socket) to ground the R&S LCX, e.g. with a grounded
external conductor.
The front panel ground socket is directly connected to the mains safety ground by the
line cord.
See Table 1-1.
USB A
Female USB (universal serial bus) connector of type A (host USB). You can connect a
