1.
Configure the Model 3162B as follows:
Function:
Square wave
Frequency:
10 MHz
Amplitude:
3 V
Remote Commands:
:RES
:FUNC:SHAP SQU

2.
Connect the A channel output to the oscilloscope input. Use the
20dB attenuator and set oscilloscope input impedance to 50
Ω
.
3
.
Set the oscilloscope and verify that the rise and fall times are less
than 2.5 ns. Verify that overshoot and ringing are less than 5% of
amplitude.
4.
Configure Channel B using the following commands:
Remote Commands:
:INST:SEL B

5.
Connect the B channel output to the oscilloscope input. Use the
20dB attenuator and set oscilloscope input impedance to 50
Ω
.
6.
Set the oscilloscope and verify that the rise and fall times are less
than 2.5 ns. Verify that overshoot and ringing are less than 5% of
