7. Sweeps
These procedures test the flatness of frequency sweeps.
Setup
Connect the + BNC of the DS360 to CH A of the scope. Connect the SWEEP OUT BNC from the rear
panel of the DS360 to CH B of the scope. Set CH A to 1 V/div, CH B to 5V/div, the time base to
50µs/div and triggering on CH B.
Procedure
1) Reset the DS360 (Turn power off, wait 2 seconds, then turn power on w/ [CLR] pressed).
2) Measure the sweep flatness for a 1 Hz to 100 kHz sweep.
a) Press
[START/CENTER] [1] [Hz]
[STOP/BW] [1] [0] [0] [kHz]
[RATE] [2] [kHz]
[AMPL] [5] [V
[SWP/BUR]
b) Expand CH A to 0.2 V/div and offset the waveform so the upper portion can be viewed.
Confirm that, excluding the first 10 µs, the waveform is flat to within 50 mV
Record the result on the test record located at the end of this section.
3) This completes the sweep test.
