Electrical Engineering Laboratory Equipment Manual
The amplitude of the pulses is set by the AMPLITUDE range/adjust knob. A dc
offset may also be added to the output pulsetrain by pulling the OFFSET knob out. The
output is taken from either the POSITIVE OUTPUT or NEGATIVE OUTPUT connectors.
Advance Instruments PG 58 Pulse Generator
The Advance PG 58 is strictly meant for generating square waves or square
pulses. Its frequency range is 0.1 Hz – 7 MHz.
The output frequency is set by the FREQUENCY range/adjust knob. For normal
operation, the DELAY range/adjust knobs should be adjusted to their minimum (fully
counterclockwise) positions. The switch beneath the FREQUENCY adjust knob should
be set to NORMAL.
If a square wave (50% duty cycle) is desired, the switch beneath the WIDTH
knob should be set to SQUARE. The WIDTH range/adjust knob will have no effect on
the output waveform. If a duty cycle other than 50% is desired, the switch should be set
to SINGLE. The width of the output pulses is now adjustable via the WIDTH
range/adjust knob.
Both positive and negative pulses are available from the MAIN PULSE
OUTPUTS. Their amplitudes are adjusted by their OUTPUT LEVEL knobs. The output
pulses may also be inverted by the NORMAL/INVERT switch. This switch should
usually be left in the NORMAL position.
Agilent 33120A Function Generator / Arbitrary Waveform Generator
The 33120A is a direct digital synthesis generator. This generator has standard
waveforms such as: sine, square, triangle, ramp, and noise. Arbitrary waveforms can
also be created. This generator can do frequency sweeps and different forms of
modulation. The generator can also be programmed over the remote interface. The
standard waveform functions are used in the laboratory classes.
There are two rows of keys on the front panel that are used to select a operation
or function. These keys have a second function printed in blue above them. To access
the functions in blue print, press the Shift key (shift annunciator turns on) and then
press the key with the desired blue print. If you press the Shift key by accident, press it
again to turn it off (shift annunciator turns off).
