1. Install the test hookup and preset the instrument controls:
Figure 41: Serial trigger baud rate test hookup
a. Hook Up the test-signal source:
(See Figure 41: Serial trigger baud rate
■
Connect the sine wave output of the sine-wave generator through a
50 Ω precision coaxial cable to Ch 1 through an adapter.
■
Set the sine-wave generator to output a 416 MHz sine wave.
b. Initialize the instrument:
Press the
Default Setup
button.
c.
Modify the initialized front-panel control settings:
■
Set the vertical
Scale
to 50 mV per division.
■
< 4 GHz models: Touch
Vertical
, select
Vertical Setup
, and then
touch Termination
50Ω
.
■
Set the horizontal
Scale
to 1 ns per division.
■
Adjust the sine-wave generator output for 4 divisions of amplitude
centered on the display.
■
Adjust the trigger
Level
to trigger at 25% (-1 division) on the sine
wave.

2. Verify that the signal path can do isolated 0 and pattern matching circuits
can do isolated 1:
a.
From the button bar, touch
Cursors
and then the
Setup
button. If using
the menu bar, touch
Cursors
and then select
