Exercise #2: Sine Wave Generator Test
Items needed: Waveform Signal Generator. Signal input leads.
I.
Real-time Recording
DISCUSSION
Input a +/- 2 Volt sine wave, 1 kHz into Channel #1. Use a one grid chart.
Set up the channel so that when there is no signal, the waveform trace will be at
the center. When the sine wave signal is applied, the waveform trace will be
shown symmetrically within the grid. The signal will be seen on the color
display as well as on the chart paper. Next, a data capture will be set up to
collect data when the sine wave signal is applied.

[RUN / HALT]
Set Channel #1 to be +/- 4 Volts FS
[AMP 1]
One key for each of two amplifiers.
[ADVANCED]
[CHANGE AMP TYPE…]
The Dash 16u has four amplifier types.
[SET TO SINGLE-ENDED]
Select the single-ended amplifier type.
[EXIT] [SET TO 40 V]
Set the attenuator range to 40 Volts.
[EXIT] [SET RANGE]
Turn encoder wheel until range is set to 8 Volts.
[SET OFFSET]
Turn encoder wheel until offset is set to 0 Volts.
[EXIT]
Input sine wave into Channel #1
Use the banana jack input connection located on the side of the Dash 16u.
Run
the
chart
[RUN / HALT]
The signal for Channel #1 should be
½
of the full scale chart.
Stop

[RUN / HALT]
Measure the sine wave signal
[FREEZE DISPLAY]
Toggle the time cursor button until it reads
using the color display
[TIME CURSOR A]
.
Turn the encoder wheel to move Cursor A. Observe the
voltage readings shown at the bottom of the display. Experiment with Cursor B
and then Cursors A+B. Amplitude and time measurements between the cursors
are given on the bottom of the display.
When finished, run the display
