8. Set the generator frequency to 100 MHz (TDS 340), 200 MHz (TDS 360), or
400 MHz (TDS 380).
9. Press MEASURE ! High-Low Setup ! Min-Max.
10. Press the main menu button Select Measurement.
11. Press the side menu button -more- until Amplitude appears in the side
menu. Press the side menu button Amplitude.
12. Press SET LEVEL TO 50%.
13. Set the test signal amplitude for about one division on screen. Fine adjust the
generator output until the CH 1 Amplitude readout indicates the amplitude
is 500 mV. (Readout may fluctuate around 500 mV.)
14. Press TRIGGER MENU ! Slope.
15. Press SET LEVEL TO 50%. Check that a stable trigger is obtained for the
test waveform on both the positive and negative slopes (see Figure 4–10).
(Use the side menu to switch between trigger slopes; use the trigger LEVEL
knob to stabilize the trigger if required.)
First, set a signal with an
amplitude at the minimum trigger
sensitivity.
Second, check for a stable
trigger at both the positive and
negative slope settings.
