Battery Operation
The R&S Cable Rider ZPH 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 display screen. See
Chapter 3.2.6, "Display Overview"
The lithium ion battery has a capacity of 6.4 Ah and it allows operation of up to nine
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 Cable Rider ZPH.
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 Cable Rider ZPH is in inactive mode
(i.e. R&S Cable Rider ZPH is switched off). If the instrument is in active mode (i.e. R&S
Cable Rider ZPH is switched on), the charging time is extended to about four hours
because the charging current is reduced as the power is partially drained by the usage
of the R&S Cable Rider ZPH.
During operation in the field, you can also charge the battery with the car adapter (R&S
HA-Z302, order number 1321.1340.02). You can connect the car adapter to the DC
port. With the car adapter, you are able to charge the R&S Cable Rider ZPH via the
car's cigarette lighter socket. A replacement battery (R&S HA-Z306, order number
1321.1334.02) with the same capacity and charging time as the battery included in the
standard delivery is also available if necessary.
Battery dispatched during delivery is not fully charged, for battery operation you have
to charge it first.
To charge the battery, connect the charger to AC power adapter included in the deliv-
ery. For more information, see
"Using an external battery charger"
Using an external battery charger
You can also use an external battery charger (R&S HA-Z303, order number
1321.1328.02) to charge the battery.
To charge the battery externally, put the battery into the external charger and supply it
with power via the AC power adapter.
An amber LED on the charger indicates the charging process. The LED turns to green
when the battery is fully charged. A red LED on the charger indicates that the battery is
not charging or the charging failed.
