, and then enter V
diff
in the test record. As an
example, on the 5 mV/div setting, if V
pos
is 17.4 mV and V
neg
is -17.2
mV, then V
diff
is 34.6 mV.
e. Enter V

Channels 3 and 4 are only on four channel oscilloscopes.
10. Set the DC voltage source to 0 V, a nd move the BNC cable to the next
channel to be tested.
11. Repeat steps 5 through 10 for each remaining channel.
Check Bandwidth
This test checks the bandwidth of all input channels.
1. Connect the output of the leveled sine wave generator (for example, Fluke
9500) to the oscilloscope channel 1 input as shown below.
2. Push the front-panel Default Setup button to set the instrument to the factory
default settings.
