Prerequisites

See page 1–15.

1. Install the test hookup and preset the instrument controls:

a. 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.

b. Modify the initialized front-panel control settings:

H

Set the horizontal SCALE for the M (main) time base to 20 ns on
the TDS 600B or 25 ns on the TDS 500C/700C.

H

Press HORIZONTAL MENU; then press the main-menu button
Time Base.

H

Press the side-menu button Delayed Only; then press the side-menu
button Delayed Triggerable.

H

Set the horizontal SCALE for the D (delayed) time base to 20 ns on
the TDS 600B or 25 ns on the TDS 500C/700C; then press the
side-menu button Main Only.

H

Press TRIGGER MENU; then press the main-menu button Mode
& Holdoff. Press the side-menu button Normal.

H

Press VERTICAL MENU; then press the main-menu button
Coupling. Press the side-menu button 

 to select the 50 

W

 setting.

H

Press SHIFT; then press ACQUIRE MENU. Press the main-menu
button Mode; then press the side-menu button Average 16.

c.

Hook up the test-signal source:

H

Connect the signal output of a medium-frequency sine wave
generator (item 19 or, optionally, item 25) to a BNC T connector.
Connect one output of the T connector to CH 1 through a 50 

W

precision coaxial cable. Connect the other output of the T connector
to the AUX TRIG INPUT

 

at the rear panel. See Figure 1–18.
