5 Calibrating the Oscilloscope
• Standard Calibration — Time scale calibration will not be performed. Time
scale calibration factors from the previous time scale calibration will be
used and the 10 MHz reference signal will not be required. The remaining
calibration procedure will continue.
• Standard Calibration and Time Scale Calibration—Time scale calibration
will be performed. This option requires you to connect a 10 MHz
reference signal to channel 1 that meets the following specifications.
Failure to use a reference signal that meets these specifications will result
in an inaccurate calibration.
• Frequency: 10 MHz, max ±41 ppb = 10 MHz, max ±0.41 Hz
• Amplitude: 0.2 V peak-to-peak to 5.0 V peak-to-peak
• Wave shape: Sine or Square
c Connect the 50 Ω BNC cable from Aux Out to each of the channel inputs as
requested.
d Connect the 50 Ω BNC cable to Aux Trig In as requested.
e Follow the directions for calibrating the digital channels (models with MSO
option).
f A Passed/Failed indication is displayed for each calibration section.
If any section has failed, wait until the calibration is complete and then select
the Enable Details check box for information on the failures. Also check the cable
connections.
5 When the calibration procedure is complete, click Close.
When performing the time scale calibration using the 53220A-010 universal frequency
counter/timer, the precision 10 MHz reference is available from the Int Ref Out connector on
the rear panel of the 53220A counter/timer.
