5) The anti-aliaising filter (used for sweeps) accuracy is verified at 1.0 V
RMS
. To do this, the DS360
is set for an externally triggered sweep, with no triggers provided. This causes the stop
frequency to be continuously output, which can be measured. For each frequency listed in step
5, perform steps 6b and 6c.
