5.1.5 Battery operation
The R&S Spectrum Rider 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 6.6.1, "Title bar", on page 32.
The lithium ion battery has a capacity of 6.4 Ah and it allows operation of up to
eight hours when it is fully charged.
The actual operation time depends on the current charged status (see Fig-
ure 5-2), the ambient temperature and the operating mode of the R&S Spectrum
Rider.
For a summary of the LED indication of the [Power] key, see Table 5-1.
The battery charging and discharging process of the battery icon indicated in the
display screen is illustrated below:
Figure 5-2: Battery charging and discharging process
Charging time is about three hours when the R&S Spectrum Rider is in inactive
mode (i.e. R&S Spectrum Rider is switched off). If the instrument is in active
mode (i.e. R&S Spectrum Rider 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 Spectrum Rider.
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 Spectrum

The maximum power that is permissible at the RF input is 20 dBm (or 100 mW).
The RF input is protected from static discharges and voltage pulses by a limiting
circuit.
RF power overload
The R&S Spectrum Rider maybe loaded with up to 30 dBm (or 1 W ) for up
to three minutes. If you apply 1 W for a longer period, the R&S Spectrum
Rider may be destroyed.

Risk of electric shock
To avoid electrical shock the DC input voltage, you must never exceed the
value specified on the housing.
Risk of damage of the R&S Spectrum Rider
To avoid damage to the coupling capacitor, input attenuator or the mixer,
the DC input voltage must never exceed the value specified in the data
sheet.
BNC connector
You can connect the BNC connector for various applications. It supports an external trigger signal or an external reference signal.
When the BNC connector is configured as a trigger input, it controls the start of a
measurement. The trigger mode is selected in the "Sweep" menu, see Chap-
ter 6.8.5, "Function keys", on page 41. The trigger threshold is similar to that of
TTL signals.
When the BNC connector is configured as reference input, you can apply a 10
MHz external reference signal to it for frequency synchronization. The external
reference label is displayed at the top right corner of the trace window to indi-

cate that the reference signal is supplied via external signal input. The label turns
green when the reference signal is detected.
The level of the reference signal must be larger than 0 dBm. If there is no reference signal present at the BNC connector, the R&S Spectrum Rider displays an
appropriate message. Thus, measurements without a valid reference can be avoided.
For more information on configuring the BNC connector for the appropriate signal,
see "Configuring the BNC connector" on page 49 and Chapter 6.10.3, "Using
the GPS receiver", on page 54.
Headphone jack
