How to Use
X
and
D
The
X
and
D
keys cause the current value of the signal to jump to a pre-determined
cardinal value, whose amount is determined by the current function. These keys are
described in more detail under the descriptions for each function.
How to Reset the SC1100 Option
You can reset all parameters in the Calibrator to their default settings at any time during
front panel operations by pressing the
R
key on the front panel.
After resetting the Calibrator, press
a
to return to the SC1100 Option (the SCOPE
menu appears.) Press
O
to reconnect the signal output.
How to Calibrate the Voltage Amplitude on an Oscilloscope
The oscilloscope voltage (vertical) gain is calibrated by applying a dc or low frequency
square wave signal and adjusting its gain to meet the height specified for different voltage
levels, as designated by the graticule line divisions on the oscilloscope. The signal is
applied from the Calibrator in VOLT mode. The specific voltages that you should use for
calibration, and the graticule line divisions that need to be matched, vary for different
oscilloscopes and are specified in your oscilloscope’s service manual.
The VOLT Function
You can calibrate the Voltage gain using the VOLT function. Access this function
through the VOLT menu, which appears when you press
a
, or when you press the
VOLT softkey from the SCOPE menu.

You can press the MODE softkey to cycle through the functions in the order shown, or
you can press

to return directly to the SCOPE menu.
Each menu item is described below:
•
OUTPUT @ SCOPE Indicates the location of the signal output. If the signal does
not appear on the oscilloscope, press
O
. To disconnect the signal, press
Y
.
•
1 M
Ω
Toggles between 1 M
Ω
and 50
Ω
to match the input impedance of the
oscilloscope.
•
DC<-AC Toggles from ac to dc, producing the dc equivalent output. DC->AC
Toggles from dc to ac.
•
TRIG If you are using square wave to calibrate the external trigger, use this key to
toggle the trigger off and on. When on, the reading will show “/1”, which indicates
that the external trigger is at the same frequency as the volt output. The external
