Prerequisites ReadPrerequisites on page 2 --17and footnote warnings on page 2--19.
1. Install the test hookupand preset the instrument controls:
a. Initialize the oscilloscope:
HPressDEFAULT SETUP.
b. Modify the default settings:
HTurnthe horizontal SCALE knob to 40 ns (50 ns for TDS5054B E).
HFrom the toolbar bar,click Horiz and sel ect the Acquisitiontab.
HClick Averageand set the number of averages to 16.
HClick ET (Equivalent Time).
HFrom the toolbars, click MEAS. Click Setup Ref Levs; then click
the Determine Base, Top From Min-Max button.
NOTE. The sine wave generator outp ut amplitude must be leveled to wit hin
0.35 db of the referencefrequency (10 MHz) throughthe bandwidth frequency
listed in Table2--3 on page 2--30. The 0.35 db requirementis necessary to ensure
a bandwidth that meets Tektronixspecifications.
Youcan perform bandwidth Performance Verification using an unleveled sine
wave generator (with amplitude error>0.35 db). Under these conditions, the
bandwidth PV is subject to the flatness errorsassociated with the generator
used.
Refer to the Sine WaveGenerator Leveling Procedure on page 2--61if your sine
wave generator does not have automatic output amplitude leveling.
Check Analog Bandwidth
