105 Microelectronics Lab 01 Introduction to Electronic Test Equipment

Objectives

To get familiar with test equipments and the HP 5461B oscilloscope. Perform DC and transient
measurements.

Procedure/Measurement Report

Use the
Oscilloscope and Signal Generator to see undercompensated
and overcompensated effects

Try the
triggering function of the oscilloscope.

Use the
Digital Multimeter to measure the given circuit.

Measure
Resistor I-V graph with DMM and oscilloscope

Perform
Transient Analysis on the given circuit.

Results/Analysis

2.1

Q 3.

1.What’s the maximum voltage the supply will produce?

The maximum
voltage is 5V peak to peak.

2.How accurate is the power supply’s panel?

The scale is
accurate to 0.5V.

3. Can this experiment be done with AC
mode? Why, why not?

This cannot be
done with AC mode because AC mode filters out the DC signals with a coupling
capacitor.

4. AC and DC coupling difference?

AC
coupling filters out the DC signals and DC coupling does not.

Q4.

1. How close to two measurements agree?

The
two measurements is extremely close, which is +-0.01V.

2. What is the maximum peak-topeak
amplitude available from the generator?

Maximum = 20V,
minimum = 100mV.

3. What
does the trigger level do?

The trigger level
shifts the waveform to left and right on the display, which is actually
shifting the beginning of the waveform.

Q5.

1. What
is the shortest pulse width? The longest?

Highest frequency 10
MHz, lowest frequency 0.1mHz. Lowest width = 1/10MHz =
10^-7s. Longest width = 1/0.1mHz=10^4s.

2.3

Q2. Voltage of node 1 and node 2? V(1) = 9.88. V(2)
= 6.57.

Q3. Derive a relationship for V(2)
in terms of Vsupply, RA and RB.

V(2) = Vsupply
– (Vsupply)/(RA + RB) x(RB)

Q4. Calculate the current through resistor RB.

The current is calculated to be 0.333 mA. The measured current is 0.336mA. The error is 1%.

2.5

Q1. Measure the resistance on a 10k ohm carbon
resistor.

The 10k ohm is
measured to be 9.875k ohm.

Q2. Learn how to perform an I-V using
oscilloscope.

10k ohm, 5V, 50mA.

2.5

Q4.
Display the waveforms on oscilloscope.

Q5.

The 100kHz graph is like the graph of 10kHz except the blue
curve is almost a horizontal line.

Conclusions

Basically the lab is to have the student be
familiar with the lab equipments. Know how to adjust the probe, the error with
the DC voltage source pane, and other lab techniques that is important to know
like AC mode and DC mode.
