User Manual 9250
Portrayal 3-11
CH1 High Frequency
Response
Equipment: Oscilloscope, waveform generator, x10 attenuator
Procedure:
50. Configure the waveform generator as follows:
51. Function: Square wave
52. Frequency: 1MHz
53. Amplitude: 1.6Vp-p (may vary depending on the
configured gain)
54. Connect the waveform generator output to the 9250 channel
1 input
55. Connect the 9250 channel 1 through the x10 attenuator to the
oscilloscope
56. Set oscilloscope to dc coupling and 50Ω termination
Adjustment:
1. Adjust RV5, RV8 and C77 for transition time between 18-20ns
and lowest aberrations
