Performance Tests
1–50 TDS 500C, TDS 600B & TDS 700C Performance Verification and Specifications
HConnect 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.
HConnect 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.
b. Initialize the oscilloscope:
HPress save/recall Setup.
HPress the main-menu button Recall Factory Setup.
HPress 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:
HSet the vertical SCALE to 200 mV.
HPress VERTICAL MENU, then press the main-menu button
Position.
HSet vertical position to –3 divisions (press –3, then ENTER, on the
keypad). The baseline level will move down three divisions. See
Figure 1–17 on page 1–51.
HPress the main-menu button Offset.
HSet vertical offset to +10 volts with the keypad. The baseline level
will move off screen.
HSet the standard output of the DC calibration generator equal to the
offset (+10 volts). The DC test level will appear on screen. See
Figure 1–17.
b. Measure the test signal:
HPress SET LEVEL TO 50%.
HPress TRIGGER MENU.
HRead the measurement results from the readout below the label
Level in the main menu, not the trigger readout in the graticule area.
