Operation modes
LED
Two LED’s mounted on the front panel show if a channels is active or not. The LED of an
active channel is lighted. During DIP mode the LED display switches from one channel to the
other.
General diagram
Drop
:
The voltage supply at channel PF1 will be interrupted for the preselected time td. The voltage at
PF2 is set to 0V. At the same time switch S2 close and connect the internal 10
load to the DUT.
This is indicated by the PF2 LED.
For the drop out test the supply voltage must be connected to PF1 input at the rear side.
V:
Channels PF1 and PF2 are supplied with different voltages; e.g. channel PF1 with nominal voltage,
channel PF2 with a reduced dip voltage.
Channel PF1 is switched off for the preselected time td. During this time the DUT is powered by the
reduced voltage of channel PF2. The “Dip voltage” is delivered through the diode..
