Maintenance and Performance Checks 3-6
2. Perform bandwidth, small signals tests on channel 1 output
using Table 3-4
3. Use the same procedure to check channels 2, 3 and 4

1.8 MHz 6 ±1.8 Divisions
Amplifier Pulse
Response
Amplifier pulse response checks the aberrations, which include rise
and fall times, overshoot and undershoot. Each channel has a
different response and therefore, the pulse response is tested on each
channel separately.
Rise/Fall Time Tests
Equipment : Oscilloscope, Arbitrary Waveform Generator, Load
Resistance, x100 high voltage probe, 50
Ω
feedthrough terminator
Preparation:
1. Configure the Oscilloscope as follows:
Time Base: 500ns
Amplitude: 100 V/div
2. Connect the 9400 Channel 1 output to the load resistance
3. Connect the x100 high voltage probe across the load resistance
4. Configure the Waveform Generator as follows:
Amplitude: 8 V
Function: Square wave
Output: On
Frequency: 50
kHz
5. 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 rise/fall time tests on channel 1 output using Table 3-5
3. Use the same procedure to check channels 2, 3 and 4
