c.
Hook up test-signal source (TDS 460 Only):
H
Connect the high-amplitude output of a calibration generator,
through a 50
W
precision cable to the input of a tunnel diode
pulser (see Figure 5-9).
H
Connect the output of the tunnel diode pulser through a 10X
attenuator to CH 1.
H
Set the triggering level of the tunnel diode pulser to minimum.
d.
Initialize the oscilloscope:
H
Press save/recall SETUP.
H
Press the main-menu button Recall Factory Setup.
H
Press the side-menu button OK Confirm Factory Init.
e.
Modify the initialized front-panel control settings:
H
Set vertical SCALE to 5 mV.
H
Press VERTICAL MENU. Then press the main-menu button
Coupling. Press the side-menu button
W
to toggle to 50
W
coupling.
H
Press SHIFT. Then press ACQUIRE MENU.
H
Press the main-menu button Mode. Then press the side-menu
button Hi Res.
H
Press CLEAR MENU.
2.
Adjust the Probe:
a.
Display and store the reference signal:
H
(TDS 410 and TDS 420 Only) Set the high-amplitude output of
the generator for a six division square wave on screen (see
Figure 5-10).
H
(TDS 460 Only) Set the high-amplitude output of the generator
for 60 to 100 V
at the input to the tunnel diode pulser (see Fig-
ure 5-11).
H
(TDS 460 Only) Advance the triggering level of the tunnel diode
pulser until a five to six division square wave appears on screen.
H
Push SET LEVEL TO 50% as required to trigger the signal.
H
Advance the horizontal SCALE to 5 ns.
H
Press HORIZONTAL MENU.
H
Press the main-menu button Trigger Position; and press the
side-menu button 10%.
H
Push SHIFT. Then press SAVE WAVEFORM.
H
Press the main-menu button Save Waveform. Then press the
side-menu button To Ref 1.
