4.3 Trying out the instrument
As a brief introduction, the following example describes the basic steps to be taken
when setting up a measurement. The instructions guide you through the measurement
of a resistor.
Further test setups and measurement methods are described in the user manual, see
Chapter 6, "Measurement setups", on page 52.
The test setup uses the R&S LCX-Z3 SMD test fixture connected to the R&S LCX for
measuring wireless components.
If necessary, you can connect the R&S LCX-Z11 BNC-to-BNC extension between the
R&S LCX and the test fixture, e.g., to make it easier to pick and place the DUTs.
Basic measurement steps
The R&S LCX LCR meter measures the impedance and phase angle with an AC sig-
nal, and derives the required characteristics.
As the equivalent circuit of each DUT contains capacitive, real and conductive parts,
the characteristics of passive components vary dependent on frequency, level, temper-
ature and additional bias. Even the test equipment can impact the measurement
results. Therefore, we recommend that you use the test fixture that fits best for your
application, and align the instrument on all frequencies. Keep the order as given to
minimize parasitic parts and thus to optimize the measurement accuracy.
1. Select the test fixture that fits best for your application.
2. After power-on set the R&S LCX to an initial state, see "Setting the initial state"
on page 32.
3. Connect the test fixture, see Chapter 4.1.9, "Connecting a test fixture", on page 23.
4. Configure the test signal, see "Setting up the test signal" on page 33.
5. Align the instrument on all frequencies, see "Aligning the instrument on all frequen-
cies" on page 34.
6. Start a resistor measurement "Measuring a resistor" on page 34.
Setting the initial state
1.
NOTICE! Check all terminals to make sure that they are not damaged.
Power on the R&S LCX, as described in Chapter 4.1.6, "Connecting to power",
on page 19.
2. Switch on the R&S LCX, see Chapter 4.1.10, "Switching on or off", on page 25.
3.
NOTICE! Risk of measurement inaccuracy. Measurements can be inaccurate, if
performed when the instrument is not warmed-up. Wait until the instrument has
reached its operating temperature before you start the measurement procedure.
The warm-up time is up to 30 minutes.
To start from an initial state, set the instrument to default:
