This procedure uses the general purpose knob on the front panel to set the Magic
Frequency parameter.
Equipment
Required
One oscilloscope (Item 1)
One SMA 50 W coaxial cable (Item 4)
SMA (Fe) to BNC (Ma) 50 W adapter (Item 5)
Do the following steps to connect the test equipment and set test equipment
controls:
1. Use a SMA coaxial cable and a SMA (female) to BNC (male) adapter to
connect the waveform generator CH1 Output connector to the CH1 input
connector on the oscilloscope.
