f. Display the test signal: Do the following subpartsto first display the
referencesignal and then the test signal.
HFrom the toolbar click MEAS; then select the Time tab.
HClick the Freq button to measurethe frequency of the current
channel.
HSelect the Ampl tab. Click the Pk-Pk button.
HClick Close button.
HSet the generatoroutput so the CH<x> Pk-Pk readout equals the
referenceamplitude in Table 2--3that corresponds to the vertical
scale set in substep d.
HPress 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 adjustmentsto the trigger level. You can use the Trigger
LEVEL knob to do this. (Full bandwidth varies with TDS model as
isshowninTable2--3.)
g. Measurethe test signal:
HSet the frequencyof the generator, as shown on the screen, to the test
frequencyin Table 2--3that corresponds to the vertical scale set in
substep d. See Figure 2--12.
HSet the horizontal SCALE to the horizontal scalesetting in
Table2--3 that correspondsto the vertical scale set in substep d.
PressPUSH TO SET 50% as necessary to trigger the signal.
HRead the resultsat the CH<x> Pk-Pk readout, which will automati-
cally measurethe amplitude of the test signal. See Figure 2 --12.
