Performance Tests
1–58 TDS 500C, TDS 600B & TDS 700C 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 50 precision cables (Item 5)
One calibration generator (Item 10)
Prerequisites See page 1–15. Also, the digitizing oscilloscope must have passed
Check DC Voltage Measurement Accuracy on page 1–29.
See Input Channels vs. Model on page 1–2.
1. Install the test hookup and preset the instrument controls:
50 coaxial cables
To MAIN

Generator Digitizing Oscilloscope
Figure 1–20: Initial test hookup
a. Hook up test-signal source 1:
HConnect the standard amplitude output of a calibration generator
through a 50 W precision coaxial cable to CH 3 (AX1 on some TDS
models).
HSet 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:
HPress save/recall SETUP.
HPress the main-menu button Recall Factory Setup.
HPress the side-menu button OK Confirm Factory Init.
