3 Operating modes, applications, channel set-
ups, and result displays
If the spectrum analysis hardware option R&S ZNLxx-B1 is installed, the R&S ZNL is
actually two instruments in one: a vector network analyzer (VNA) and a spectrum ana-
lyzer (SA). The R&S ZNL integrates the functionality of the two as separate operating
modes in one instrument. The advantage is that you can perform typical network ana-
lyzer tasks on a dedicated network analyzer, and spectrum analyzer tasks on a dedica-
ted spectrum analyzer, without having to buy, maintain, and set up two individual
instruments. Furthermore, you can easily and quickly switch between measurement
tasks in different operating modes, and hardly notice the difference in operation. Both
are just different applications on the same instrument. Internally, however, the data is
processed using entirely separate hardware, always optimized to the selected operat-
ing mode.
●A spectrum analysis" hardware option is not available for the R&S ZNLE and for
R&S ZNL14 and R&S ZNL20 with serial numbers below 101200.
●Note that interruptions in analog output may occur if you switch between a VNA
and a spectrum application, due to the separate hardware. In particular, if you run a
sequence of measurements including both measurement types, switching between
both modes can interrupt the signal from the output connector.
The Spectrum operating mode allows you to perform all sorts of different analysis tasks
on different types of signals, e.g. Analog Demodulation, I/Q analysis or basic spectrum
analysis. Depending on the task or type of signal, a different set of measurement func-
tions and parameters are required. Therefore, the Spectrum operating mode provides
various applications - some of which are included in the base unit, others are optional.
The default application when you start the R&S ZNL is "VNA", for basic network analy-
sis.
Channel Setups
When you activate an application, a new channel setup is created which determines
the measurement settings for that application. The same application can be activated
with different measurement settings by creating several channel setups for the same
application.
The number of channel setups that can be configured at the same time depends on the
available memory on the instrument.
For more information on creating channel setups, see Chapter 3.3, "Defining channel
setups", on page 22.
