Setup for NRZ Signals
NRZ signal setup consists of first connecting the oscilloscope to a NRZ-encoded
serial bus signal, then specifying the signal, bus configuration, and other settings.
To set up the oscilloscope to capture NRZ signals:
1 Press [Serial].
2 Press the Serial softkey and choose the serial decode (Serial 1 or Serial 2) to
use; then, press the softkey again to enable decode.
3 Press the Mode softkey; then, select the NRZ decode mode.
4 Press the Signals softkey to open the NRZ Signals Menu.
In the NRZ Signals Menu:
a Press the Source softkey to select the channel connected to the NRZ signal
line.
The label for the NRZ source channel is automatically set.
b Press the Threshold softkey; then, enter the trigger threshold voltage level.
The threshold voltage level is used in decoding and will become the trigger
level when the trigger type is set to the NRZ serial decode.
c Press the Baud softkey; then, enter the baud rate of the NRZ signal from your
device under test.
The baud rate can be set from 5 kb/s to 5 Mb/s in 100 b/s increments.
You must set the baud rate to match your device under test.
The default baud rate is 125 kb/s.
d Press the Back/Up key to return to the Serial Decode Menu.
