Model No. CI-7599
750 Interface (USB)
7
Using the Interface as a Signal Generator
(no amplifier required):
The 750 USB interface contains a built-in function generator for
creating up to eight types of waveforms (sine, square, triangle,
sawtooth, ramp up, ramp down, positive ramp up, positive ramp down,
as well as DC voltages.) when the interface is used with DataStudio.
No power amplifier is required for signal generation. The computer is
used as an AC signal generator to power external circuits while it
monitors its own output current as well as other inputs. Using the 750
interface, DataStudio can create an analog signal that ranges in
frequency from DC to 50 KHz, with an amplitude of +/- 5 volts, and
with a current of up to +/- 300mA. For specific frequency, range, and
amplitude limits, see Appendices A (Specifications) and C (subsection
“Built-In Function Generator/Amplifier”) in this manual.
To use the Interface as a Signal Generator for a Circuit (or
Other Device):
1.
Insert a banana plug into the
Ground port
(
)
on the interface, and
connect the ground lead to the ground on the circuit board (or other
device).
2.
Insert a banana plug into the
Signal Generator port
(
)
and
connect the lead to the positive lead on the circuit board (or other
device).
3.
Below the Sensors list, click on the Signal Generator icon to open
the Signal Generator dialog box.
4.
In DataStudio, use the Signal Generator dialog box to choose the
type of wave, and control the amplitude, frequency, and voltage
output.
5.
To create signals, click the
Start
button.
Note: Using DataStudio,
you can also generate
waves without a Power
Amplifier connected to
the interface. See “Using
the Interface as a Signal
Generator” in this man-
ual.
