Performance Verification
5. Set the oscillo
scope as follows:
a. 1 mV/division
b. 1MΩ input resistance
c. 20 MHz bandwidth (BW) limit
d. AC Coupled
e. Line trigger
f. 2ms/div
g. Set to measure V
p-p
and V
RMS
6. Set the oscilloscope probe to 1X mode.
7. Set the channel under test (CUT) to the 100% FS output voltage.
8. Set the CUT to the 100% FS output current.
9. Turn the DUT output on.
WARNING. Do not touch the load resistor. The load resistor may become hot
enough to cause burns.
10. Enter the oscilloscope measurements into the table for checking Noise at
7 MHz. (See Table 24 on page 22.)
This completes the check for one channel. If needed, return to step 1 to run
through the check for the next channel.
