9.7.13 Internal Li-ion batteries
R&S FPL1-B31
With the Li-ion battery pack (option R&S FPL1-B31), the R&S ZNL can be operated
independently of an AC or DC power supply. The instrument can house 2 Li-Ion batter-
ies which can be charged both via AC or DC power supply.
This option is not available for the R&S ZNLE. For the R&S ZNL, it can be retrofitted by
Rohde&Schwarz service.
9.7.14 Power sensor measurements (R&S ZNL only)
R&S ZNL only
The connection of an external power meter to the R&S ZNL can serve different purpo-
ses.
●
Extended measurement functionality: Each external power meter represents an
additional receive port. External power meters increase the number of RF input sig-
nals of a DUT that the analyzer can measure simultaneously. They can also pro-
vide accurate results for signals at inaccurate or unknown frequencies. A typical
example is a mixer measurement with an unknown LO signal (and therefore
unknown IF output frequency).
●
Power calibration: An external power meter can measure the exact signal power at
an arbitrary point in the test setup (reference plane) and thus provide the reference
values for a power calibration. A typical example is a source power calibration for
an arbitrary analyzer port.
