TDS 500D, TDS 600B & TDS 700D Performance Verification and Specifications
Output Signal Checks
The procedure that follows checks those characteristics of the output signals that
are listed as checked under Warranted Characteristics in Specifications. The
oscilloscope outputs these signals at its front and rear panels.
Equipment
required
Two precision 50 W coaxial cables (Item 5)
One calibration generator (Item 10)
Prerequisites See page 1–15. Also, the oscilloscope must have passed Check DC
Voltage Measurement Accuracy on page 1–32.
See Input Channels vs. Model on page 1–2.

Figure 1–20: Initial test hookup
a. Hook up test-signal source 1:
H Connect the standard amplitude output of a calibration generator
through a 50 W precision coaxial cable to CH 3 (AUX1 on some
TDS models).
H Set the output of the calibration generator to 0.500 V.
b. Hook up test-signal source 2: Connect the Main Trigger Out at the rear
panel to CH 2 through a 50 W precision cable.
c. 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.
