Time Base Marker Calibration Procedure for an Oscilloscope
This sample procedure uses the Time Marker function to verify the horizontal deflection
(time base) of your oscilloscope. See your manual for the oscilloscope for the time base
values recommended for calibration.
Before you start this procedure, make sure that you are in Marker mode. If you are, the
Control Display shows the subsequent menu, see below.

Do the subsequent sample procedure to calibrate the time base.
1. Connect the Calibrator to Channel 1 on the oscilloscope. Select 50Ω impedance or
use an external 50 Ω termination. Make sure the oscilloscope is dc-coupled.
2. Apply a time marker value. Refer to the recommended calibration settings in your
oscilloscope manual. For example, to key in 200 ns, push
, and then push .
Note
You can record the equivalent frequency as an alternative to the time
marker value. For example, as an alternative to 200 ns, you can record
5 MHz.
3. Set the time base of your oscilloscope to show 10 time markers. The time markers
must align with the oscilloscope divisions, as shown in the example below. For an
accurate indication, align the peaks of the signal with the horizontal center axis, see
below.
