Note
Normal color of the digital reading is dark blue. If you
modify the reading, the color changes to a lighter shade of
blue, indicating that the 3156B has not been updated yet
with the new parameter. Pressing Execute will update the
instrument and will restore the color of the digital readout
to dark blue, indicating that the displayed value is the
same as the generator setting.
Also note that the digital readout has an autodetect
mechanism for the high and low limits. You cannot exceed
the limits if you are using the dial but only if you use the
keypad. In case you do, the program will not let you
download an illegal parameter and you’ll be requested to
correct your setting.

Sample Clock
The Sample Clock group is comprised of parameters that control the
sample clock mode and frequency. The 3156B has two sample clock
ranges: 200MS/s and 100MS/s. Using the 200MS/s sample clock
frequency, the number of waveform points is restricted to even
number only. If you use waveform data files that contain data that
does not divide by 2, then the 100MS/s sample clock range must be
used. Select the appropriate sample clock range by clicking on the
200MS/s or 100MS/s buttons.
