Connect the output of the DC calibration generator, through a
dual-banana connector followed by a 50
W
precision coaxial cable,
to one side of a BNC T connector. See Figure 1–15.
Connect the Sense output of the generator, through a second
dual-banana connector followed by a 50
W
precision coaxial cable,
to other side of the BNC T connector. Now connect the BNC T
connector to CH 1. See Figure 1–15.
b. Initialize the oscilloscope:
Press save/recall Setup.
Press the main-menu button Recall Factory Setup.
Press the side-menu button OK Confirm Factory Init.
2. Confirm Main trigger system is within limits for Trigger-level/Threshold
accuracy:
a. Display the test signal:
Set the vertical SCALE to 200 mV.
Press VERTICAL MENU, then press the main-menu button
Position.
Set vertical position to –3 divisions (press –3, then ENTER, on the
keypad.) The baseline level will move down three divisions. See
Figure 1–16 on page 1–46.
Press the main-menu button Offset.
Set vertical offset to +10 volts with the keypad. The baseline level
will move off screen.
Set the standard output of the DC calibration generator equal to the
offset (+10 volts). The DC test level will appear on screen. See
Figure 1–16.
b. Measure the test signal:
Press SET LEVEL TO 50%.
Press TRIGGER MENU.
Read the measurement results from the readout below the label
Level in the main menu, not the trigger readout in the graticule area.
c. Read results (Check against limits): See Figure 1–16.
CHECK that the Level readout in the main menu is within 9.940 V
to 10.060 V, inclusive.
