The Standard
Waveforms Panel
The Standard Waveforms panel, as shown in Figure 3-4, may be ac-
cessed a number of ways: click on it to bring it to the foreground,
click on the STD. button on the Instruments bar, or click on the Stan-
dard button in the Waveforms group of the Main Panel. The func-
tional groups in the Standard Waveforms Panel are described below.
Parameters
The Parameters group contains two parameters: Amplitude and Off-
set. To access the desired parameter, click on the button below the
two indicators until the LED next to the desired parameter turns on.
The value that is associated with the lit LED is displayed on the digi-
tal display. You can use the dial, keyboard, or the [↑] [↓} keys to ad-
just the readout. After you modify the setting, press Execute to up-
date the 3155.
Note
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 the high and low limits. You cannot ex-
ceed 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 and an error
message displays.
Frequency
The button in the Frequency group lets you program the output fre-
quency for the selected waveform shape. The frequency parameter
may be modified when the LED illuminates. You can use the dial,
keyboard, or the [

setting. After you modify the setting, press Execute to update the
3155.
