Performance Check Procedure
g. CHECK-that the dvm display reads =GI mV rms.
e. Set the front panel pushbuttons for a
5 V 1.6 A output
voltage.
h. Connect the oscilloscope vertical input to the front
panel POSITIVE and common terminals through a
1X
f.
Alternately open and close the switch in series with the
probe.
5 11 load.
Ac couple the oscilloscope input. Set the bandwidth
limit to
20 MHz.
CHECK-that
' the oscilloscope reads ~10 mV peak-
to-peak.
Repeat this check for the NEGATIVE floating supply.
The specifications are identical.
Remove these connections for the next step.
6. Check Load Transient Recovery
a.
Make certain the OUTPUT is OFF.
Connect the test fixture shown in Fig. 5-2 to the front
panel common and POSITIVE output connectors.

c.
Connect the oscilloscope to the front panel POSITIVE
and common connectors.
g. Adjust the oscilloscope triggering so that the transient
waveform during switch opening and closing is visible
on the oscilloscope display.
