TDS 500C, TDS 600B & TDS 700C Performance Verification and Specifications
1. Install the test hookup and preset the instrument controls:
a. Initialize the instrument:
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 default setup:
H Press VERTICAL MENU.
H Press the main-menu button Coupling; then press the side-menu W
button to select 50 W coupling.
H Set the horizontal SCALE to 10 ns on the TDS 600B and 12.5 ns on
the TDS 500C/700C.
c. Hook up the test-signal source: Connect the output of a
medium-frequency leveled sine wave generator (Item 25) to CH 1. Do
this through a 50 W precision coaxial cable, followed by a 10X
attenuator. See Figure 1–14.

2. Confirm the trigger system is within time-accuracy limits for pulse-glitch or
pulse-width triggering (Horizontal Scale ≤1 ms):
a. Display the test signal: Set the output of the sine wave generator for a
100 MHz, five-division sine wave on screen. Press SET LEVEL TO
50%.
