Connecting the probe to your circuit
Attach the probe to the circuit using the connectors and adapters shown on the back of these instructions. Select the best
method for your needs, and then proceed to Setting up the P robe.
Setting up the probe
To set and vi
ew the digital channel parameters, do the following:
On MS O/DPO5
000 Series instruments, select Vertical>Digital Setup or push the D15-D0 button.
On MSO/DPO4
000B Series instruments, push the D15–D0 button.
The parame
ters listed below can be set on each digital channel:
Threshold
voltage and vertical position (the default threshold setting is 1.4 V)
Signal hei
ght and position (set once for all 1 6 c hannels)
Channel l

To set and
view bus characteristics, do the following:
On MSO/DP
O5000 Series instruments, use the controls in the Bus Setup menu.
On MSO/D
PO4000B Series instruments, push the B1 to B4 buttons.
The setu
p s creens allow you to set and view bus characteristics such a s:
Clock ty

lel bus setup information is resident on some oscilloscope models. However, for other buses such as SPI and I2C, you
must have the appropriate option. See your oscilloscope manual or product data sheet for nomenclature and ordering details.
Functional check
Logic activity immediately displays on all connected, active channels. If you do not see an active signal:
1. Push the Trigger button.
2. Select Edge for trigger type.
3. Select the channel that you are setting up as the source.
4. On MSO/DPO4000B Series instruments, push the Autoset button.
If you do not see an active signal, try another probe channel (or analog probe) to verify circuit activity at the test point.
