a Decide if you want to perform the Time Scale Calibration. Your choices are:
b Disconnect everything from all inputs and Aux Out.
c Connect the 50 Ω BNC cable from Aux Out to channel 1.
d Connect the 50 Ω BNC cable from Aux Out to each of the channel inputs as requested.
e Follow the directions for calibrating the digital channels (MSO models only).
f A Passed/Failed indication is displayed for each calibration section. If any section fails, check
After the calibration procedure is completed, click Close.

Chapter 2: Calibration
The routine will ask you to do the following things in sequence:
• 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 - Performs the time scale calibration. 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 this specification will result in an
inaccurate calibration.
Frequency: 10 MHz ±0.4 ppm = 10 MHz ±4 Hz
Amplitude: 0.2 Vpeak-to-peak to 5.0 Vpeak-to-peak
Wave shape: Sine or Square
• Standard Calibration and Reset Time Scale Calibration - Factory time scale calibration factors
will be used. The 10 MHz reference signal will not be required. The remaining calibration
procedure will continue.

a little section on what to do if a self cal fails in terms of replacing assemblies.
