Check Analog Bandwidth
This test check
s the bandwidth at 50 Ω for each channel.
1. Connect the output of the leveled sine wave generator (for example, Fluke
9500) to the oscilloscope channel 1 input as shown in the following
illustration.
WARNING. The generator is capable of providing dangerous voltages. Be sure to
set the generator to o ff or 0 volts before connecting, disconnecting, and/or moving
the test hookup during the performance of this pro cedure.
2. Push the front-panel Default Setup button.
3. Select 50 Ω impedance as follows:
a. Set the calibrator to 50 Ω output impedance and to generate a sine w ave.
b. Push the front-panel channel 1 button.
c. Set the Termination (input impedance) to 50 Ω.
4. Set the Acquisition mode to Sample as follows:
a. Push the front-panel Acquire button.
b. Push the Mode lower-bezel button (if not already selected).
c. Push the Sample side bezel button.
5. Set the Vertical Scale to 1mVper division.
6. Adjust the signal source to at least 8 vertical divisions at the selected vertical
scale with a se t frequency of 50 kHz. For example, at 5 mV/div, use a
≥40 mV
p-p
signal, at 2 mV/div, use a ≥16 mV
p-p
signal, and at 1 mV/div, use a
≥8mV
p-p

7. Set the Horizontal Scale to 10 μs per division.
8. Record the peak-to-peak measurement:
a. Push the front-panel Wave Inspector Measure button.
b. Use the Multipurpose b knob to select the Peak-to-Peak measurement.
