Taking Delay Measurements
This example shows another way to measure trace parameters, using
cursors. When the measurement you want to make is not included in the list
of automated measurements, you can use cursors.
You will use the cursors to take two common measurements, trace ampli
tude and delay between traces. The 11801C can do both of these as auto
mated measurements, so you can compare the method of using automated
measurements to using cursors.
For this example you will need a 11801C with at least one dual channel
sampling head installed two SMA cables of equal length, and a static protec
tion wrist strap.
Step 1: Initialize the 11801C (press the UTILITY button in the MENUS
column, touch Initialize in the major menu, and touch Initialize in the
verification pop up menu).
Step 2: Put on the wrist strap and ensure that it is connected to the
antistatic connector on the front panel of the 11801C.
Step 3: Connect the CALIBRATOR output to a sampling head input.
Step 4: Connect the INTERNAL CLOCK output to any available sam
pling head input.

Step 5: Press the TRIGGER button. Touch Source in the major menu
area and select Internal Clock, then touch Exit.
Step 6: Press the SELECT CHANNEL button on the sampling head
input channel you have connected to the calibrator signal.
