information, see the topic
“System Calibration”
in
the
“Calibration”
section). The default allowable
range is ±200Vp (with system gain set to 20). This
range is displayed above the selected input box.
When a value outside of the allowable range is
entered, the input box will turn red.
Frequency:
The Start Frequency and End Fre-
quency properties determine the frequency of the
wave in cycles per second (Hertz). Frequency can
be defined using Hertz (Hz) or Kilohertz (kHz) as
the unit of measure. When the unit of measure
is changed, the 3110 automatically converts the
property’s value to the new unit of measure. The
units of measure used for Start Frequency and
End Frequency do not need to be the same.
The allowable minimum value for Start Frequency
is 0.1 Hz. The allowable maximum value for End
Frequency is 20 kHz. This range is displayed
above the selected input box. When a value out-
side of the allowable range is entered, the input
box will turn red.
DC Offset:
The Start Offset and End Offset prop
-
erties supply a constant positive or negative DC
voltage on the AC wave. DC Offset is defined in
Volts DC (VDC) as the unit of measure.
The allowable range for Start and End Offset is
±200 VDC (with system gain set to 20). This range
is displayed above the selected input box. When a
value outside of the allowable range is entered, the
input box will turn red.
Amplitude Sweep Type:
An Amplitude Sweep
can be Linear, Exponential or Logarithmic. Choose
the desired sweep type from the drop-down.
When Exponential is chosen as the sweep type,
an additional variable, the effective time constant,
is added to the properties window. The effective
time constant has an allowable range from -8 to
+8. Increase or decrease this variable to affect the
rate of exponential change. To change the expo-
nential curve from convex to concave, vary the
sign of the effective time constant. See the topic
“Creating an Exponential Sweep”
in the
“Tutori-
als”
section for more information.
Clip Amplitude:
Select the Clip Amplitude check
box to enable the waveform clip feature. When
enabled, the Clip Amplitude will create a clipped
waveform at the voltage specified. The default
Clip Amplitude voltage setting is 200 Vp, which
is effectively a non-clipped waveform since AC
wave amplitude is limited by the system to 200 Vp.
Change the Clip Amplitude voltage to a level be-
tween 0 and 200 Vp to clip the waveform. NOTE:
The default clip amplitude can changed from 200
Vp to the setting of your choice on the Segment
Defaults tab in the Settings window. See the topic
“The Segment Defaults Tab”
in the section
“Set-
tings Window”
for more information.
Frequency Sweep Type:
A Frequency Sweep can
be Linear, Exponential or Logarithmic. Choose the
desired sweep type from the drop-down.
When Exponential is chosen as the sweep type,
an additional variable, the effective time constant,
is added to the properties window. The effective
time constant has an allowable range from -8 to
+8. Increase or decrease this variable to affect the
rate of exponential change. To change the expo-
nential curve from convex to concave, vary the
sign of the effective time constant. See the topic
“Creating an Exponential Sweep”
in the
“Tutori-
als”
section for more information.
Phase Angle:
The Phase Angle property deter-
mines the beginning offset of the waveform within
the cycle. Phase Angle can be defined using
degrees (deg) or radians (rad) as the unit of mea
-
sure.
The allowable range for Phase Angle is 0 to 360
degrees. This range is displayed above the select-
ed input box. When a value outside of the allow-
able range is entered, the input box will turn red.
