1
Set up the oscilloscope according to the table above.
a
Press the Chan key.
b
Move the cursor to the V/Div field, then use the RPG knob to dial in the V/Div values
shown on the first line of the table.
c
Move the cursor to the Offset field. Use the front-panel keyboard to enter the offset
value shown on the first line of the table. Use the left and right cursor-control keys to
select either mV or V.
2
Acquire the zero input voltage.
a
Disconnect the power supply from the channel input.
b
Press the blue shift key, then press the Run key. Wait for approximately five seconds
(averaging complete), then press Stop.
c
Press the Markers key. Move the cursor to the Va Volts field. Using the RPG knob,
move the Va marker over the oscilloscope trace on the display.
3
Acquire the measured voltage.
a
Connect the power supply to the channel input. Set the power supply voltage
according to the first line of the table above.
b
Press the blue shift key, then press the Run key. Wait for approximately five seconds
(averaging complete), then press Stop.
c
Press the Markers key. Move the cursor to the Vb Volts field. Using the RPG knob,
move the Vb marker over the oscilloscope trace on the display.
d
Record the voltage in the Va to Vb field in the performance test record.
4
Repeat steps 1 through 3 for the second line of the table, then for the rest of the lines
of the table for channel 1.
5
Repeat from "Set up the logic analyzer" for channel 2, replacing channel 1 with
channel 2 where applicable.
