What is an Instrument?
1. A tool or implement, especially one
for delicate or scientific work.
"a surgical instrument“
2. A measuring device used to gauge
the level, position, speed, etc. of
something, especially a motor vehicle
or aircraft.
Power Supply
A dual-output laboratory power supplies voltage and current
are indicated on three-digit display, can be operated in parallel
or in series, and can be operated as constant voltage source or
as constant current source.
The main attributes of this device is:
1.Voltage and current are indicated on separate LED-meters.
2.The output voltages are available through safety sockets on the front
panel.
3.Dual Tracking (Serial and parallel operation) Both lab-outputs can be
connected in parallel or in series by means of a switch on the front
panel. The left hand unit is then operating as the master control unit.
4.The output values are indicated on the meters of the master unit.
5.The units are equipped with a third output supplying a fixed voltage of
3...6 Volts and a max. Current of 2 A. This output is located on the right
side with safety sockets.
6.output on/off switch.
Multimeter
digital multimeters are designed to
measure resistance, current and voltage,
and the RMS value of sinusoidal current
and voltage. also measure the true RMS
(TRMS) value of any waveform.
Function Generator
•
A FG provides voltages of different forms.
These may include: sinusoidal, triangular, and
square. An adjustable level of DC off set (+ or -)
may also be available. In addition, a control may
be present to vary the waveform symmetry.
Output-voltage frequency and amplitude may
have a wide dynamic range.
Oscilloscope
•
This is one of the most important pieces of laboratory test
equipment. It is basically a voltage sensing and display
device; it cannot measure current directly. However, it can
be used to measure a voltage proportional to a desired
current, e.g., across a small sampling resistance.
•
Most modern Scopes have two input channels with
adjustable, calibrated, gain. Two signals can thus be
viewed separately, or simultaneously if they are
synchronized. Calibrated gain settings enable the
measurement of voltage amplitude.
Project Board (Bread Board)
• A breadboard (protoboard) is a construction base
for prototyping of electronics, because the
solderless breadboard does not require soldering,
it is reusable. This makes it easy to use for
creating temporary prototypes and experimenting
with circuit design.
