Figure 30 Setup for ripple immunity with swapped voltage and current measurement channels
The above figure shows the setup for a closed-loop ripple immunity testing. The AMP 200N measurement
channels are used to measure the ripple current and voltage at the EUT terminals.
Recommended equipment:
Differential voltage probe
Active current probe
Shunt capacitor
Verification Resistor
Hints for the setup:
- Use active voltage and current probes (to match the impedance of the AMP measuring channels).
Passive probes are not suitable.
- Power the differential voltage probe with batteries. Using an external power supply may generate
interference that disturbs the ripple test.
- AMP measurement channels can be swaped in case higher voltage measurement resolution is required.
In this case additional adapters from BNC to 4mm lab connectors (or vice versa).
- It is recommended to first verify the setup and performance using a verification load instead of the EUT.
