If your generator cannot output 6 divisions of amplitude, determine its maximum
output at the Test frequency, and use this for the reference amplitude. The - 3 db
limit can be calculated as: 0.707 × reference amplitude.
f. Display the test signal: Do the following subparts to first display the
reference signal and then the test signal.
H From the button bar touch MEAS; then select the Time tab.
H Touch the Freq button to measure the frequency of the current
channel.
H Select the Ampl tab. Touch the Pk-Pk button.
H Touch Close button.
H Set the generator output so the CHx Pk-Pk readout equals the
reference amplitude in Table 4--7 that corresponds to the vertical
scale set in substep d.
H Press the front-panel PUSH TO SET 50% as necessary to trigger a
stable display. At full bandwidth, you may also want to make small,
manual adjustments to the trigger level. You can use the Trigger
LEVEL knob to do this. (Full bandwidth varies with TDS model as
isshowninTable4--7).
g. Measure the test signal:
H Set the frequency of the generator, as shown on screen, to the test
frequency in Table 4--7 that corresponds to the vertical scale set in
substep d. See Figure 4--20.
