NOTE. The sine wave generator output amplitude must be leveled to within
0.35 db of the reference frequency (10 MHz) through the bandwidth frequency
listed in Table 1–4. The 0.35 db requirement is necessary to ensure a bandwidth
that meets Tektronix specifications.
You can perform bandwidth PV using an unleveled sine wave generator (with
amplitude error > 0.35 db). Under these conditions, the bandwidth PV is subject
to the flatness errors associated with the generator used.
Refer to the Sine Wave Generator Leveling Procedure on page 1–88 if your sine
wave generator does not have automatic output amplitude leveling.
c. Hook up the test-signal source: Connect the sine wave output of a
leveled sine wave generator to CH 1. Set the output of the generator to a
reference frequency of 10 MHz or less. See Figure 1–7.
For the optional setup using a leveled sine wave generator with a
leveling head, see Figure 1–8 and, if using this optional setup with the
example Tektronix SG 504, set the generator output to 6 MHz.
