8.8.5.1 About binning
To perform binning, the R&S LCX requires the bin configuration you must define and
upload in advance. In addition, you must configure the test signal (i.e. level and fre-
quency) and bias, compensation and measurement range settings before. Changing
these settings is not possible during a binning session.
To specify the bin configuration, you can define up to 8 categories according to 2 mea-
surement characteristics in a *.csv file, e.g. using a suitable application. Optionally,
you can configure the last bin to denote the end of each measurement, independently
of the result. Another control signal denotes if a component exceeds the specified lim-
its. You can assign these results to a bin also.
To upload the file, use a USB flash drive. When the binning function is enabled, the
R&S LCX measures the connected component initiated by a trigger signal. It indicates
the result, i.e. the corresponding bin on the screen, and also assigns a signal at one of
the 8 digital bin outputs.

Contents of the *.csv file:
●
Up to 2 measurement parameters
●
The measured value range of each of the two parameters for the individual bin.
●
The value ranges of the measurement parameters defined for the corresponding
categories (up to 8 bins).
●
How the limits are specified:
– Minimum and maximum values
– Nominal value and percentage deviation
– Nominal and deviation value
●
Additional signals you want to have assigned at the output, i.e. end of measure-
ment, out of bin, both).
With the binning function enabled, the R&S LCX switches to measurement mode "trig-
gered" automatically. The measurement starts with the first trigger signal. You can
either trigger the measurement manually, using the [Trig.] key at the front or by sending
the remote command *TRG. It is also possible to apply an external trigger signal to the
"Trigger Input" connector at the rear of the instrument.
During the binning measurements, the R&S LCX is permanently in the triggered mode
and cannot be disabled.
How to: see Section 8.8.5.5, "Configuring and using the binning function",
on page 116.
For details on the trigger modes, see the specifications document, section "Digital trig-
ger and control interfaces".
8.8.5.2 Assignment of the binning interface
The digital I/O port of the binning interface is a 15-pole D-Sub female socket, including
eight data lines. The remaining pins provide digital input and output of control signals.

For details on the interface specification, see section "Digital trigger and control interfa-
ces" in the specifications document.

8.8.5.3 Binning settings
In the "Binning" menu, you can upload the binning file, and start the measurement.
Access:
1. Press the [settings] key at the front panel.
2. In the "Functions" tab, select "Binning".
Figure 8-27: Binning menu
In the initial softkey menu, you can load the binning file and activate the measure-
ment.
During the process, the main screen indicates the parameters related to the mea-
surement, and access to the bin configuration.
The required remote commands are described in Section 11.12, "HANDler subsystem",
on page 214.
