3.1.1.5 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", on page 31.
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 Figure 3-2), 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 Table 3-1.
The battery charging and discharging process of the battery icon indicated in the display 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 delivery. For more information, see "Using an external battery charger" on page 22.
Using an external battery charger
You can also use an external battery charger (R&S HA-Z303, order number

Instrument damage caused by cleaning agents
Cleaning agents contain substances that may damage the instrument. For example,
cleaning agents that contain a solvent may damage the front panel labeling, plastic
parts, or the display.
Never use cleaning agents such as solvents (thinners, acetone, etc.), acids, bases, or
other substances.
The outside of the instrument can be cleaned sufficiently using a soft, lintfree dust
cloth.

Power meter input / RF Input
For model .02, the built-in power-meter provides a maximum power measurement of
30 dBm (or 1 W) at the RF input port. Connect a cable or DUT to the RF input with an
N-type connector. Use a cable to connect the DUT to the R&S Cable Rider ZPH, if necessary.
For model .12, the RF input allows a maximum power of 20 dBm (or 100 mW) at the
RF input port. The R&S Cable Rider ZPH may be loaded with up to 30 dBm (or 1W) for
up to three minutes. If you apply 1 W for a longer period, the R&S Cable Rider ZPH
maybe destroyed. The RF input is protected from static discharges and voltage pulses
by a limiting circuit. Connect a cable or DUT to the RF input with an N-type connector.
Use a cable to connect the DUT to the R&S Cable Rider ZPH, if necessary.
Risk of electrical shock
To avoid electrical shock, the DC input voltage must never exceed the value specified
on the housing.

Risk of instrument damage
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. It can also be configured as a BIAS port.
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. 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 indicate 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 Cable Rider ZPH displays an appropriate message. Thus, measurements without a valid reference can be avoided.
When the BNC connector is configured as an internal DC bias port, the BNC connector
provides direct current output. Active equipment under test can be supplied with power
via the bias port.
Risk of instrument damage
To avoid damage to the tracking generator output, never apply currents greater than
600 mA or voltages greater than 20 V to the BNC connectors if the BNC connectors
are not configured as BIAS output ports.
If they are configured as BIAS ports, never apply currents greater than 600 mA or voltages greater than 50 V.
Headphone jack
The 3.5 mm connector for headphones has an internal impedance of approximately 10
Ω.
USB type A connector
The USB port provides the USB interface to connect a memory stick and store data
sets or screenshots. It can also be used to control the operation of the external power
sensor.

RF out / Reflection
For model .02, the RF out connector provides a signal source output power at -10.00
dBm nominal.
For model .12, the RF out connector provides the following ways to generate a signal
source output power at -10.00 dBm nominal.
●
Tacking generator output
●
Continuous signal source output
●
Coupled continuous signal source output
For model .12, the RF out connector can also be configured as an internal DC bias
port. When the RF out is configured as a BIAS port, the RF out connector provides
direct current output. Active equipment under test can be supplied with power via the
bias port.
Risk of electrical shock
To avoid electrical shock, the DC input voltage must never exceed the value specified
on the housing.
Risk of instrument damage
●
Make sure not to overload the RF input and keep within the maximum allowed signal levels. Refer to the datasheet for the maximum allowed signal levels.
●
To avoid damage to the coupling capacitor, input attenuator or the mixer, the DC
input voltage of 50 V must never be exceeded.

● Measuring Harmonics.............................................................................................81
4.7.1 Attenuating the Signal
You can attenuate the signal to a suitable level either manually or automatically.
In case of automatic attenuation, the level of attenuation at the RF input depends on
the current reference level. The R&S Cable Rider ZPH provides two ways of automatic
attenuation.
For the highest possible sensitivity, it provides the "Auto Low Noise" attenuation mode.
For the lowest possible intermodulation, it provides the "Auto Low Distortion" mode.
The main difference between the two modes is that the attenuation level is 5 dB to 10
dB higher in case of "Auto Low Distortion" than it is for "Auto Low Noise". In the default
state, "Auto Low Distortion" is active.

4.7.2 Using the Preamplifier
The R&S Cable Rider ZPH has an optional preamplifier (R&S ZPH-B22, order number
1334.5627.02) to increase sensitivity. Depending on the frequency, the gain of the
amplifier is in the range from 15 dB to 20 dB and increases the sensitivity by 10 dB to
15 dB.
In the signal path, the preamplifier comes after the input protection circuit and before
the RF attenuator of the R&S Cable Rider ZPH to provide excellent sensitivity when
the preamplifier is switched on.
1. Press the [SCALE/AMPT] key.
2. Select the "Att/Amp/Imp" softkey.
3. Enable or disable the "Preamp" checkbox to turn on or off the preamplifier of the
R&S Cable Rider ZPH.

80User Manual 1321.0950.02 ─ 07
Setting the reference level
The level at the top of the measurement diagram is called the reference level. To
obtain the best dynamic range from the R&S Cable Rider ZPH, you should use its full
level range. That means that the maximum level value should be at or close to the top
of the measurement diagram (= reference level).
1. Press the "REF" softkey at the "Parameter view".
The R&S Cable Rider ZPH opens an entry box to enter the reference level.
2. Enter a reference level of -25 dBm.
The R&S Cable Rider ZPH reduces the reference level by 5 dB.
The maximum trace value is close to the maximum scale value of the measurement
diagram. The increase in the displayed noise floor is minimal. The difference between
the signal maximum and the displayed noise (i.e. the dynamic range) has, however,
been increased.
Using markers
The R&S Cable Rider ZPH has markers to read out signal levels and frequencies.
Markers are always positioned on the trace. Both the level and frequency at their current positions are displayed on the screen.
► Press the [MARKER] key.
The R&S Cable Rider ZPH activates a marker and puts it on the maximum value
on the trace. The coordinates of the marker are shown in a table above the measurement diagram.

Using the Spectrum Analyzer
Page 88
Basic Operation
R&S®Cable Rider ZPH
81User Manual 1321.0950.02 ─ 07
Measuring the frequency
The trace consists of 711 measurement points (frequency points). The marker is
always positioned on one of these measurement points. The R&S Cable Rider ZPH
calculates the marker frequency from the frequency of the measurement point, the
center frequency and the frequency span that have been set. The measurement-point
resolution, and consequently the accuracy of the marker frequency readout, therefore
depend on the frequency span that has been selected.
The R&S Cable Rider ZPH has a frequency counter to increase the accuracy of the
marker-frequency readout. It completes the sweep, then counts the frequency at the
marker position.
1. Press the "Marker Function" softkey at the "Parameter view".
2. Select the "Frequency Count" from the menu item.
The measurement result of the frequency counter is displayed in the "Measurement
result view". When the frequency counter is active, the resolution of the frequency
readout is always 0.1 Hz, regardless of the span. The accuracy is determined by the
internal reference frequency which is far more exact than the pixel-oriented marker
readout.
4.7.4 Measuring Harmonics
A spectrum analyzer is ideal to measure harmonic levels or harmonic ratios, because it
can resolve different signals in the frequency domain.
With marker functions, you can speed up the measurement tasks.
A signal generator, e.g. R&S SMBV provides the signal source.

4.8.2 Measuring Power and Return Loss
With the directional power sensors R&S FSH-Z14 and R&S FSH-Z44, you can measure the power in both directions.
When you connect the directional power sensor between the source and the load, the
R&S Cable Rider ZPH measures the power from the source to load (forward power)
and from the load to source (reverse power).
The ratio between the forward and reverse power is a measure of the load matching.
The R&S Cable Rider ZPH displays it as the return loss or standing wave ratio.
The power sensors for the R&S Cable Rider ZPH have an asymmetrical design. Therefore, they have to be inserted into the test setup in such a way that the "Forward" arrow
on the sensor points toward the load (in the direction of the power flux).
When measuring high powers, pay strict attention to the following instructions to avoid
personal injury and to prevent the power sensor from being destroyed.
Danger of skin burns and damage to the instrument
●
Never exceed the permissible continuous power.
●
See diagram on the rear of the sensor for the permissible continuous power.
●
