Calibrating
Select Options > Calibrate > Reset to set the generator's calibra-
tion factors to default nominal values.
Press Options > Calibrate > Full Scale.
Set the voltmeter's scale factor to be able to measure a nominal
1000 millivolts DC.
Using a VGA-to-BNC cable, connect the generator's red output to
the positive input on the voltmeter, with a 75 ohm (+/- 1%) input
terminator. Connect the negative lead of the meter to any ground
pin.
Select R_FS+ or -R_FS to set the DC output level to 1000 mV
+/- 3 mV.
Repeat steps 4 and 5 for the green and blue outputs.
Select Save.
Select Options > Calibrate > Zero.
Connect the red output to the positive input of the voltmeter.
