Testing Performance
To verify bandwidth
To verify bandwidth
This test verifies bandwidth. In this test you will use an oscilloscope calibrator
with a level sinewave output.
You will use the peak-to-peak volt age both at 1 MHz and at bandwidth frequency
to verify the bandwidth response of the oscilloscope.
54622A, 54622D, and 54624A
Test limits at 1 mV/div to 5 V/div:
• All channels (±3 dB)
• dc to 100 MHz
• ac coupled 10 Hz to 100 MHz
54621A and 54621D
Test limits at 1 mV/div to 5 V/div:
• All channels (±3 dB)
• dc to 60 MHz
• ac coupled 10 Hz to 60 MHz
