3 In the Waveform Generator Settings Menu, press the Logic Presets
softkey.

In the Waveform Generator Logic Level Presets Menu, press one of the
softkeys to set the generated signal's Low and High voltages to logic
compatible levels:
To add noise to the waveform generator output
1
If the Waveform Generator Menu is not currently displayed on the
oscilloscope's softkeys, press the
[Wave Gen] key.
2 In the Waveform Generator Menu, press the Settings softkey.
3 In the Waveform Generator Settings Menu, press the Add Noise softkey
and turn the Entry knob to select the amount of white noise to add to
the waveform generator output.
Note that adding noise affects edge triggering on the waveform generator
source (see
"Edge Trigger" on page 168) as well as the waveform generator
sync pulse output signal (which can be sent to TRIG OUT, see "Setting the
Rear Panel TRIG OUT Source" on page 339). This is because the trigger
comparator is located after the noise source.
Softkey (logic levels) Low level High level
TTL 0 V +5 V (or a
TTL-compatible high level
if +5 V cannot be
reached)
CMOS (5.0V) 0 V +5 V
CMOS (3.3V) 0 V +3.3 V
CMOS (2.5V) 0 V +2.5 V
ECL -1.7 V -0.9 V
