Performance Veri
fi
cation Procedures
The Performance Veri
fi
cation Procedures consist of a self test and several check
steps, which check the instrument's performance to speci
fi
cations. The following
three conditions must be met before performing these procedures:
1.
The oscilloscope must have been operating continuously for twenty (20)
minutes in an environment that meets the operating range speci
fi
cations for
temperature and humidity.
2.
You must perform the Signal Path Compensation (SPC) operation described
in step 2 of the
Self Test
before evaluating speci
fi
cations. (See page 55,
Self
Test
.) If the operating temperature changes by more than 10 °C (18 °F), you
must perform the SPC operation again.
3.
You must connect the oscilloscope and the test equipment to the same AC
power circuit. Connect the oscilloscope and test instruments to a common
power strip if you are unsure of the AC power circuit distribution. Connecting
the oscilloscope and test instruments to separate AC power circuits can
result in offset voltages between the equipment, which can invalidate the
performance veri
fi
cation procedure.
The time required to complete the entire procedure is approximately one hour.
WARNING.
Some procedures use hazardous voltages. To prevent electrical
shock, always set voltage source outputs to 0 V before making or changing any
interconnections.
