3 Start-up and measurement

The P1401/P1501 or P1402/P1502 IC test system can be used to measure the immunity of
integrated circuits (ICs) to magnetic and electric fields in the frequency range of up to 1 GHz and
3 GHz, respectively. The immunity to electric fields and magnetic fields is measured separately.
The basic measurement set-up, the measurement princple and a description of the individual
components of the test systems can be found in section 2.
3.1

Measuring devices

The ICE1 test environment and P1401/P1501 or P1402/P1502 IC test system from
Langer EMV-Technik GmbH are used to carry out immunity measurements. In addition, the
following devices are needed for the measurement set-up:

Signal generator to generate a test signal

RF power amplifier to generate the required power

Directional coupler (optional) to measure the forward and reverse power

Spectrum analyzer (optional) to monitor the signal at the measurement output of the field
source

Oscilloscope to monitor the functions and/or signals of the IC

PC to automate the measurement
Note: Since the field sources are operated under short-circuit conditions or under open-circuit
conditions, as described in section 2, the power amplifier is terminated and operated with the
respective mismatch. The power amplifier used in this set-up must be designed for this purpose,
i.e. it must be stable under open-circuit conditions and short-circuit proof.
3.2

Test board

The test IC must be put into operation for the measurement. A test board for the specific IC thus
has to be manufactured for the following tasks:
- Provision of the signals and supply voltages required for test IC operation
- Provision of connections for devices such as an oscilloscope to monitor the operation condition
and/or detect faults
For further information on manufacturing the test board, please refer to IEC 62132-1 and the

"IC test instructions" .
