7.3.2. Test Setup for Reference Measurement
For the verification the power resistors are connected at the front side of the PFM 200N100.1. Make sure to
connect correct the HIGH and LOW terminals. Use low inductive resistance components.
CAUTION
Connecting the CA LV124-Pxx Loads
The
BNC Connection
of the connected
CA LV124-Pxx must
be at the top.
Mounting the incorrect orientation may result in a short
between oscilloscope earth and the positive supply terminal!
