Bandwidth Tests
Equipment
:
Oscilloscope, Arbitrary Waveform Generator, 50
Ω
feedthrough terminator
Preparation:
1. Configure the Oscilloscope as follows:
Time Base:
200
μ
s/div
Amplitude: 1
V/div
2. Connect the 9400 Channel 1 output monitor to the Oscilloscope
input
3. Configure the Waveform Generator as follows:
Amplitude:
8 V
Output: On
Frequency:
As required for the tests
4. Connect the waveform generator to Channel 1 input. Terminate
the waveform generator using the 50
Ω
feedthrough terminator at
the 9400 input
Test Procedure
1. Using the variable vertical adjustment on the oscilloscope,
adjust the vertical trace to show exactly 6 vertical divisions
2. Perform bandwidth tests on channel 1 output monitor using
Table 3-9
3. Use the same procedure to check channels 2, 3 and 4
