Specifications

To verify bandwidth
In this test you verify bandwidth by using a power meter and power sensor to
set output of a signal generator at 1 MHz and at 100 MHz. You use the
peak-to-peak voltage at 1 MHz and at 100 MHz to verify the bandwidth
response of the oscilloscope. The test is repeated at 5 mV/div (75-MHz
bandwidth).
Test limits at 10 mV/div to 5 V/div:
all channels (
±
3 dB)
dc to 100 MHz
ac coupled 10 Hz to 100 MHz
Test limits at <10 mV/div:
all channels (
±
3 dB)
dc to 75 MHz
ac coupled 10 Hz to 75 MHz
