Instructions

6. Disconnect the test setup.
7. Repeat steps 1 on page 15 through 6 on page 16 for all input channels.
Check bandwidth
This test checks the bandwidth of all input channels.
1. Set up the oscilloscope using the following table:
Push menu button Select menu option Select setting
Default Setup - -
Channel 1 Probe 1X
Acquire Average 16
Trig Menu Coupling Noise Reject
Measure Source Channel under test
Measurements Peak-Peak
2. Connect the oscilloscope channel under test to the leveled sine wave generator as shown in the following figure:
3. Set the oscilloscope Vertical Scale (volts/division) to 500 mV/div.
4. Set the oscilloscope Horizontal Scale (seconds/division) to 10 μs/div.
5. Set the leveled sine wave generator frequency to 50 kHz.
6. Set the leveled sine wave generator output level so the peak-to-peak measurement is between 2.98 V and 3.02 V.
7. Set the leveled sine wave generator frequency to:
• 200 MHz if you are checking a TBS1202C
• 100 MHz if you are checking a TBS1102C
• 70 MHz if you are checking a TBS1072C
• 50 MHz if you are checking a TBS1052C
8. Set the oscilloscope Horizontal Scale (seconds/division) to 10 ns/div.
9. Check that the peak-to-peak measurement is ≥ 2.12 V.
10. Disconnect the test setup.
11. Repeat steps 1 on page 16 through 10 on page 16 for all input channels.
Check sample rate accuracy and delay time accuracy
