"Test Signal Voltage"

Varies the test signal voltage level during the measurement process.

"Frequency"

Varies the frequency of the test signal.

"Voltage Bias"

Varies the voltage bias value.

"Current Bias"

Varies the voltage bias value.

Remote command:

DIMeasure:SWEep:PARameter on page 202

Minimum

Sets the first value of the range used for the selected sweep parameter.

Remote command:

DIMeasure:SWEep:MINimum on page 201

Maximum

Sets the last value of the range used for the selected sweep parameter.

Remote command:

DIMeasure:SWEep:MAXimum on page 201

Interval Type

Opens a selection editor to select the mode how the instrument calculates the width or

time between the recorded sweep parameters within the measurement range (Min/

Max).

"Step Size"

Uses the interval between one sweep parameter value to the next,

set with Step Size.

"Number of Points"

Uses the number of values within the range of minimum and maxi-

mum sweep parameter settings, set with Number of Points.

Remote command:

DIMeasure:INTerval:TYPE on page 201

Step Size

Sets the interval between each sweep step within the measurement range Min/Max).

Depending on the selected sweep parameter, the R&S LCX provides the correspond-

ing value and unit.

"xx V"

For Sweep Parameter > Test Signal Voltage or Voltage Bias, sets the

increment in V.

"xx Hz"

For Sweep Parameter > Frequency, sets the time interval in Hz.

"xx A"

For Sweep Parameter > Current Bias, sets the increment in A.

Abort

Aborts a running dynamic impedance measurement process.

Remote command:

8.8.4.2 Using the dynamic impedance measurement function

The dynamic impedance measurement function records the measurement readings

automatically. The R&S LCX stores the data in a log file with a generically created file-

name, either on the USB flash drive or in the instrument internal memory directory.

The dynamic impedance measurement function acquires the measurement values

from both the currently selected primary and from the secondary measurement pair.

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 data file:

► Follow the steps described in "Selecting the memory location" on page 105.

Measuring in dynamic impedance measurement mode

1. Press the [settings] key at the front panel.

2. In the "Functions" tab, select "Dynamic Impedance Measurement".

3. Configure the required settings.

4. Depending on the selected interval type, configure the value for the step size or the

number of points to set the values of the sweep parameter within the range.

To start the dynamic impedance measurement process, turn

"Enabled".

A dialog box appears that shows the progress of the dynamic impedance measure-

ment.

Note: Do not press any buttons on the instrument while the process is running. As

a dynamic impedance process can take a long time, you can abort the measure-

ment with "Abort" on page 109.

When completed, the R&S LCX displays a graphical view of the acquired measure-

ment data. It saves the generated log file with the filename indicated on the upper

left side of the screen.

Canceling a dynamic impedance measurement

Once you have started the process, you can cancel the measurement in the progress

dialog displayed.

1. Select "Abort".

The R&S LCX displays a message informing you on the recorded log file and its

storage location.

2. Confirm with "OK".

3. To evaluate the report in the log file:

a) If necessary, connect a USB memory device at the front panel "USB" connec-

tor.

b) Use the file manager to copy the log file to the memory device, see Sec-

tion 9.1.3, "File manager settings", on page 122.

c) Upload the file on a PC.

For evaluation, you can use any application that supports *.csv file format.

8.8.5 Binning

Option: R&S LCX-K107

The binning function enables you to sort a set of electrical components according to

the measured characteristics. The R&S LCX measures a connected component and

categorizes it based on a predefined bin configuration. You can see the corresponding

result on the screen, and also get the category assigned at one of the digital outputs of

the interface I/O port.
