Figure 3-16: Measurement Of Analog Bandwidth - Tektronix MSO70000 Series Technical Reference

Performance Tests (MSO70000/C Series, DSA/DPO70000B/C Series, and DPO7000 Series)
MSO70000/C, DSA70000B/C, DPO7000B/C, DPO7000, MSO5000, DPO5000 Series
Adjust the output of the generator until the reading on the power meter
is equal to the reading recorded on the power meter in step f.
MSO71254C and DSA/DPO71254/B: Using the Multipurpose knobs,
adjust Cursor 1 to the top of the waveform and Cursor 2 to the bottom
of the waveform. Read the absolute value of the result at the ΔV
readout.
All instruments except the MSO71254C and DSA/DPO71254/B:
Read the results at the Chx Amplitude mean readout, which will
automatically measure the amplitude of the test signal. (See
Figure 3-16.)

h. Check against limits:
CHECK that the measured amplitude is within the limits for the
current vertical scale setting in the table.
Enter the voltage on the test record.
When finished checking, set the horizontal Scale back to the 20 ns.
