User Manual 3155
Parameters The Parameters group contains buttons for adjusting Amplitude, Off-
set, and active segments. The values exhibited in this group are ex-
actly the same as in the Main Panel, so every time you change am-
plitude and offset in the Parameters group, the other panels are up-
dated automatically. You can also select the active segment from this
group.
To access the required parameter, click on the button below until the
LED next to the required parameter turns on. The value that is asso-
ciated with the lit LED is displayed on the digital display. You can use
the dial, keyboard, or the [↑] [↓} keys to adjust the readout to the re-
quired setting. After you modify the reading, press Execute to update
the 3155 with the new reading.
The 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 3155 has not been up-
dated yet with the new parameter. Pressing Execute up-
dates the instrument and restores 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 high and low limits. You cannot exceed
the limits if you are using the dial but you can if you use
the keypad. In that case, the program will not allow the
download of an illegal parameter.
