The voltage range of the AC power supply is 100 V to 240 V AC.
After the R&S
ZNH is connected to the power supply, you can turn it on with the
[Power] key on the front panel.
3.1.1.5
Battery Operation
The R&S
ZNH has a smart battery indicator which displays the battery charging status
on the [Power] key as well as the battery icon shown at the top right corner of the dis-
play screen. See
Chapter 3.2.6, "Display Overview"
The lithium ion battery has a capacity of 6.9Ah / 74Wh (at nominal voltage of 10.80V)
and it allows operation at preset condition of up to 4 hours when it is fully charged.
The actual operation time depends on the current charged status (see
), the
ambient temperature and the operating mode of the R&S
ZNH.
For a summary of the LED indication of the [Power] key, see
.
The battery charging and discharging process of the battery icon indicated in the dis-
play screen is illustrated below:
Figure 3-2: Battery charging and discharging process
Charging time is about three hours when the R&S
ZNH is in inactive mode (i.e.
R&S
ZNH is switched off). If the instrument is in active mode (i.e. R&S
ZNH is switched
on), the charging time is extended to about five hours because the charging current is
reduced as the power is partially drained by the usage of the R&S
ZNH.
