"Duration"
Records measurement readings within a defined time period.
To set the time period, see "Duration" on page 104.
Data logging starts immediately with Enabled > ON. It stops after the
duration time has elapsed.
"Span"
Records measurement readings from a certain start time for a defined
time span.
To set the parameter, see "Duration" on page 104.
Data logging starts at the start time and with Enabled > ON. It stops
automatically after the duration time has elapsed.
Remote command:
LOG:MODE on page 221
Interval
Sets the time period for data logging.
The measurement interval specifies the time between the recorded measurement val-
ues.
Note: You can set the instrument to log each measurement performed by setting the
interval value to 0 s, regardless of the selected measurement mode.
Remote command:
LOG:INTerval on page 221
Count
Sets the number of measurement readings for data logging Mode > Count.
Remote command:
LOG:COUNt on page 220
Duration
Sets the time period for data logging Mode > Duration or Mode > Span.
The maximum logging duration is 96 hours.
Remote command:
LOG:DURation on page 220
Start Time
Sets the time for starting data logging in Mode > Span.
At first, you can set the date. When confirmed, the dialog for setting the time opens
automatically.
How to: see "Configuring logging settings" on page 105.
Remote command:
LOG:STIMe on page 221
Set Date & Time ← Start Time
Accesses the "Set Date & Time" function to configure a date and time stamp for the
recorded data in logging Mode > Span.

8.8.3.2 Using the logging function
The logging function enables you to record the measurement readings. The R&S LCX
stores the data with a generically created filename either on the USB flash drive or in
the instrument internal memory directory.
To select the measurement parameter pairs:
► Proceed as described in "Selecting the parameters" on page 73
Remote commands:
FUNCtion:IMPedance[:TYPE][:PRIMary] on page 212
FUNCtion:IMPedance:TYPE:SECondary on page 213
Selecting the memory location
To determine the destination for saving the logging data file:
1. Press the [settings] key at the front panel.
2. In the "Functions" tab, select "Logging".
3. To determine the memory location, e.g., manually:
a) Select "Save Location".
The R&S LCX opens a selection editor.
b) In the selection editor, select "Manual".
c) Confirm your selection.
4. If you have connected an external USB memory device:
a) Select "Target Folder".
The R&S LCX opens a selection editor.
b) Select "USB1A".
c) Confirm with "Select".
Note: With no USB connected, the instrument displays a message and automati-
cally sets the internal partition, when confirmed.
The R&S LCX saves the logging file in the predefined logging folder on the
selected memory location.
Configuring logging settings
The example shows the settings for logging mode "Span", with the parameters "Inter-
val", "Duration" and "Start Time" defined.
To configure the settings and activate logging:
1. Press the [settings] key at the front panel.
2. In the "Functions" tab, select "Logging".

3. Select "Mode" > "Span".
A selection editor opens.
4. Select "Span".
5. Confirm you selection.
6. To set the time parameters for the selected mode:
a) Select "Interval"
b) In the on-screen keypad, enter time and unit, e.g. "0.1 s".
c)
Confirm with
.
d) Proceed the same way to set the duration and the start time.
Note: For the start time, the R&S LCX opens a selection editor, providing date set-
tings, and steps to a second editor for setting the start time at the selected date.
The R&S LCX starts logging at the defined date and time, and stops after the dura-
tion time has elapsed. It generates the filename and saves the logging data in the
specified memory location, see "Selecting the memory location" on page 105.
To configure the other logging modes, proceed the same way.
8.8.4 Dynamic impedance measurement
Option: R&S LCX-K106
The dynamic impedance measurement function allows you to acquire a measurement
series from the currently selected measurement pairs by sweeping the test signal.
The R&S LCX sweeps through the range of test signal parameter values and records
the acquired measurement data in a log file.
After completing a sweep cycle, the R&S LCX displays the recorded measurement
graphically in the logging chart viewer. See Section 8.8.2, "Logging chart viewer",
on page 97.
Interactions and characteristics
The R&S LCX calculates the dynamic impedance measurement parameters according
to the test signal settings. I.e., changing the frequency, range or voltage of the test sig-
nal impacts the sweep parameter values, ranges and limits.
8.8.4.1 Dynamic impedance measurement settings
Option: R&S LCX-K106
Access:
1. Press the [settings] key at the front panel.
