- In-built power supply
- User's manual.
A typical kit consists of several key modules that allow you to interact with the CPU without needing a full operating system.
-
The CPU (Intel 8085): The heart of the kit, an 8-bit processor that manages data and instructions.
-
Memory (RAM & EPROM): Usually comes with 8KB of RAM (for your programs) and 8KB of EPROM (storing the "Monitor Program" that tells the kit how to boot).
-
Input/Output (I/O)
-
Hex Keypad: Used to enter hex codes (0-F) and commands like SUB (Substitute), EXM (Examine), and GO.
-
7-Segment Display: Usually 6 digits—four for the memory address and two for the data at that address.
-
Peripheral Interface (8255 PPI): A chip that lets you connect external hardware like LEDs, motors, or sensors. Programming on a trainer kit is a very manual, tactile process. You don't type "print('hello')"; you talk to the hardware directly.

LOW PASS FILTER / HIGH PASS FILTER
LOW PASS FILTER (RC TYPE)DefinitionA Low Pass RC Filter allows low-frequency signals to pass through while attenuating (reducing) high-frequency signals.
Circuit Description-
Resistor (R) connected in series with the input
-
Capacitor (C) connected in parallel to ground
-
Output taken across the capacitor
-
At low frequencies, the capacitor offers high reactance, so the output voltage is almost equal to input.
-
At high frequencies, capacitor reactance decreases and it bypasses the signal to ground, reducing output.
- HIGH PASS FILTER (RC TYPE)Definition
A High Pass RC Filter allows high-frequency signals to pass while blocking low-frequency signals.
Circuit Description-
Capacitor (C) connected in series with the input
-
Resistor (R) connected to ground
-
Output taken across the resistor
-
At low frequencies, capacitor reactance is high, so the signal is blocked.
-
At high frequencies, reactance decreases, allowing the signal to pass to output.
-
Components are mounted on the panels are:
• RESISTANCE • Capacitors
SALIENT FEATURES:
• Front panel built with high class insulated Printed Circuit Board
sheet with well printed circuits and symbols.
• Connections are brought out through 4mm Colored Sockets.
• Patch Cords 4mm.

- De Sauty Bridge Applications Trainer Board
Here are some De-Sauty Bridge Trainer Kits / related products you might be referring to — educational lab kits used for learning how a De-Sauty bridge circuit works and how to measure unknown capacitance in electrical labs.
A De-Sauty bridge is a type of AC bridge circuit used primarily to determine unknown capacitance by balancing two arms of the bridge. Trainer kits are educational/beginner lab systems used in electronics and electrical engineering courses to demonstrate this principle in practice.
- An External sine wave oscillator (typically ~1 kHz) that provides AC excitation.
- Adjustable decades of resistance and capacitance in bridge arms.
- A null detector (speaker, meter, or headphone) to find the balanced point.
- Patch cords and sockets so students can connect and experiment with the circuit.
- Decade resistance and capacitance arms: Rotary switches let you vary known resistances/capacitances to find the balance point.
- Measure unknown capacitance by balancing the bridge.
- Understand how AC bridge circuits work (including effect of frequency on impedance).
- Power Supply: Mains operated (~230 V AC) with built-in regulated DC for internal circuits.
- Housed in a panel or cabinet with clearly printed controls.
- Often supplied with an instruction manual explaining theory, objectives, procedures, and experiments.

A Digital to Analogue Converter (DAC) Characteristic Apparatus is an electronic training and testing setup used to study, observe, and verify the operating characteristics of a DAC. It converts given digital input codes (binary numbers) into corresponding proportional analogue output voltages or currents, allowing analysis of parameters such as resolution, accuracy, linearity, monotonicity, and step size.
This apparatus is commonly used in electronics laboratories and training institutes to understand the practical behavior and performance of DACs through experimental measurement and graphical plotting of digital input versus analogue output.
H.L. SCIENTIFIC INDUSTRIES
Objective:- To study digital to analog converter using r-2r network.
Features:- Instrument comprises of DC regulated power supply 5vdc/150ma, ±15vdc/150ma, 1 voltmeter, 4 SPDT switches, provided for selecting logic '1' & logic '0', one output indicators, circuit diagram printed on the front panel.
The Digital to Analog Converter (DAC) Characteristic Apparatus is used to study and verify the relationship between digital input and corresponding analog output voltage.
Digital Input Application :- A digital input (binary code) is applied to the DAC using toggle switches / logic inputs provided on the apparatus.
Binary Weighting :- Each input bit has a specific binary weight (MSB has highest weight, LSB lowest).
The DAC internally uses a resistor network (R–2R ladder or weighted resistors) to assign proportional voltages to each bit.
Current / Voltage Summation :- The weighted currents or voltages from all active bits are summed together inside the DAC circuit.
Conversion to Analog Output :- The summed value is converted into a corresponding analog voltage using an operational amplifier.
Output Measurement :- The analog output voltage is measured using a voltmeter or multimeter connected at the output terminal.
Characteristic Observation:- By changing the digital input from 0000 to 1111 (or full range), the output voltage increases in uniform step increments, showing a staircase characteristic.
The experiment conclusion that:
-
Analog output voltage is directly proportional to the applied digital input.
-
DAC produces stepwise increasing output, validating correct digital-to-analog conversion.

Introduction:
the resistivity measurements of semiconductors can not reveal whether one or two types of carriers
are present; nor distinguish between them. However, this information can be obtained from hall
coefficient measurements, which are also basic tools for the determination of carrier density and
mobilities in conjunctions with resistivity measurement.
hall effect experiment consists of the following:
1) . Hall probe (ge. Crystal mounted on a pcb).
2) . Electromagnate 10,000 gauss.
3) . Power supply for electromagnete.
4) . Constant current power supply with two digital meters.
digital millivotmeter 0-200mv sensitivity ± o. Lmv. Auto polarity.
digital milli ampere-meter 0-20ma , sensitivity ± 0. 01ma.
5) . Digital gauss meter with hall probe, 20kg .
