Description
AL-E084 VARACTOR
DIODE CHARACTERISTICS TRAINER (DIGITAL)
Product Code: AL-E084
Product Name: Varactor Diode Characteristics Trainer (Digital)
-------------------------------------------------------------------------------------------------------------------------------------------------------
The AL-E084 Varactor Diode
Characteristics Trainer (Digital) is a compact laboratory training system
designed for practical study of the V-I characteristics of a varactor diode.
The trainer integrates regulated DC power, digital voltage/current measurement,
variable voltage control, and a sine-wave oscillator on a single instructional
panel.
2.
Scope of Learning
The trainer is designed for the
following experiment:
- Study of V-I characteristics of a
Varactor Diode.
- Observation of variation in diode
current with applied voltage.
- Measurement of input voltage and
output voltage using onboard digital voltmeters.
- Measurement of diode current using the
onboard digital ammeter.
- Study of voltage-controlled operation
of the varactor diode.
- Practical operation using 4 mm
patch-cord connections.
