MSO 3.1 kHz stair-step sine wave output

of DAC @ ~1.5 Vpp, 0.75 V offset

DAC input signals are internally

routed to digital channels D0 through

~3.1 kHz sine wave filtered from DAC

output @ ~ 600 mVpp, 300 mV offset

RFBurst 5-cycle burst of a 10 MHz amplitude

modulated sine wave @ ~ 2.6 Vpp,

0 V offset occurring once every 4 ms

Off

LFSine 30 Hz sine wave @ ~2.7 Vpp, 0 V

offset, with very narrow glitch near

each positive peak

Off

FMBurst FM burst, modulated from ~100 kHz

to ~1 MHz, ~5.0 Vpp, ~600 mV offset.
