Performance Verification Procedure

Bandwidth

Equipment needed: Fluke calibrator (preferred) or signal generator

1. Connect your calibrator’s output to CH1 of the oscilloscope

by 50ohm feed thru connector.

2. Set CH1 input attenuation to 5 mV/div, DC coupling, and

horizontal scan to 500 ns/div.

3. Turn on output of the calibrator for a 1 MHz sine wave.

4. Change the output level of calibrator until waveform height

is 6 divisions and reading is 30 mVpp.

5. Record these values as a reference value.

6. Slowly increase frequency output of calibrator up to rated

bandwidth of the oscilloscope.

7. Observe waveform and reading on screen. The size of the

waveform should always be ≥ 4.2 divisions, and reading

should always be ≥ 21.2 mV.

8. Repeat the above steps for CH2.
