a Decide if you wish to perform the Time Scale Calibration. Your choices are:
b Disconnect everything from all inputs and Aux Out.
c Connect the cal cable from Aux Out to channel 1.
d Connect the cal cable from Aux Out to each of the channel inputs as requested.
e Connect the 50 Ω BNC cable from the Aux Out to the Aux Trig In on the rear panel of
f A Passed/Failed indication is displayed for each calibration section. If any section fails,

The routine will ask you to do the following things in sequence:
• Std - 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.
• Std + Time - 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
• Std + Dflt - Factory time scale calibration factors will be used. The 10 MHz reference
signal will not be required. The remaining calibration procedure will continue.
You must use the 54855-61620 cable assembly with two 54855-67604 adapters. Failure
to use the appropriate cal cable will result in an inaccurate calibration.
