Check analog bandwidth
This test checks the bandwidth at 50 Ω termination for each channel. The typical
bandwidth at 1 M Ω termination is checked on the MSO/DPO5200/B and MSO/
DPO5100/B series products as a functional check.
1. Connect the output of the leveled sine wave generator 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 off or 0 volts before connecting, disconnecting,
and/or moving the test hookup during the performance of this procedure.
2. Push the front-panel Default Setup button.
3. Set the impedance to 50 Ω as follows:
a. Set the calibrator to 50 Ω output impedance, and to generate a sine wave.
b. Push the front-panel oscilloscope Vertical V menu button.
c. Under Termination, click 50 Ω.
4. Set the Vertical Scale to 1 mV.
5. Set the Acquisition mode to Sample as follows:
a. Push the front-panel Acquire button.
b. In the Acquisition window, select the Acquisition tab at the left.
c. Click Sample Acquisition mode.
6. Adjust the signal source to 8 vertical divisions at the selected vertical scale
with a set frequency of 50 kHz. For example, at 5 mV/div, use a ≥40 mV
p-p
signal, and at 2 mV/div, use a ≥16 mV
p-p
signal.
NOTE. At some V/div settings, the generator may not provide 8 vertical
divisions of signal. Use the maximum output setting of the generator to
obtain as many vertical divisions of signal as possible.
7. Set the Horizontal Scale to 1 ms/division.
