TDS1000B and TDS2000B Series Oscilloscope Service Manual
This test checks the edge trigger sensitivity for all input channels.
1. Set up the oscilloscope using the following steps:
Push menu button Select menu option Select setting
DEFAULT SETUP — —
CH 1 Probe 1X
TRIGGER Mode Normal
ACQUIRE Sample —
MEASURE
Source Channel under test
Type Pk-Pk
2. As shown below, connect the oscilloscope channel selected in the table to the
leveled sine wave generator.

3. Set the oscilloscope VOLTS/DIV to 500 mV/div.
4. Set the oscilloscope SEC/DIV to 25 ns/div.
5. Set the leveled sine wave generator frequency to 10 MHz.
6. Set the leveled sine wave generator output level to approximately 500 mV
p-p
so that the measured amplitude is approximately 500 mV. (The measured
amplitude can fluctuate around 500 mV.)
7. Push SET TO 50%. Adjust TRIGGER LEVEL as necessary and then
check that triggering is stable.
8. Set the leveled sine wave generator frequency to:
H 40 MHz if you are checking a TDS1001B
H 60 MHz if you are checking a TDS1002B, TDS2002B, or TDS2004B
