The MINI-LAB provides seven independent instruments in a
single compact cabinet for use in the laboratory or
classroom to supply signals and power for a wide range of
measurements and experiments in the fields of electronics,
chemistry and bio-medical engineering.
The functions available include:-
(a) Sine, square, triangle, pulse and ramp generator with
variable symmetry and D.C. offset controls producing a wide
variety of waveforms from 0.001 Hz to 1MHz which can be
amplitude and frequency modulated by an external signal.
(b) A ramp generator 5 sec to 50m sec.
(c) A switched power amplifier/bi-polar power supply/5 Volt
supply combination.
(d) An operational Amplifier with variable gain.
(e) Two variable power supplies -1 to -15V and +1 to +15V at
1 Ampere output.
(f) A 0^ + 200V variable power supply.
(gj A centre tapped 12.6V A.C. supply, and
(h) Numerous instrument combinations by link interconnection.
2.1 Waveform: Sine, triangle or square, pulse and ramp with
amplitude or frequency modulation.
2.2 Frequency range: 8 Decade ranges calibrated from 0.01 Hz
to 1 MHz plus a 200kHz to 2MHz range. An additional
uncalibrated section of the dial extends range to 0.001 Hz.
Dial covers 2 decades on each range.
Calibration: ±3% of full scale 10Hz - 1MHz.
2.3 Voltage output: Two simultaneous levels 10 Volts p-p
open circuit, 5 Volts p-p
into 600Q.
1 Volt p-p open circuit, 0.5 Volts p-p into 600f2.
Variable output provides continuous control of >100:1 of
both outputs whilst maintaining a constant 600Q output
impedance. Outputs, overvoltage and short circuit proof.
Sinewave output level : Less than ±2% level variation over
calibrated frequency range into 600Q ±5% between 1 and 2MHz.
2.4 Output offset: Output normally centered symmetrically
about ground. Push/pull switch applies a continuously
variable 0 to ±5 Volts offset voltage on open circuit.
Control also doubles as ramp frequency control (see 2.8 below).
NOTE: 0-1V output has ±0.5V offset.
2.5 Syr.n.'.ctry (fixed): ±2% from 0.01Hz to 1 MHz
(calibrated portion of dial).
Symmetry (variable) : Pulse or ramp waveforms. Continuously
variable from 1:1 to over 1:50 or 50:1 by switch selection.
Applies to sine, triangle or
square waveforms. Variable control also doubles as ramp
amplitude (see 2.8 below).
2.6 Sine wave distortion: <1.5% 10Hz to >50kHz <2% at 1MHz
(typically
0.6% 20Hz to 50kHz).
Square wave rise time: lOOnsec into 600Q load and <50pf
capacitance.
Triangle linearity: >99% within calibrated range on dial up
to 100kHz.
Triangle symmetry: Better than 2% within calibrated range up
to 100kHz.
2.7 Frequency modulation: Function Generator can be swept
over 2 decades by the internal ramp generator or over 4
decades by an external log sweep. It can also be used as an
externally programmed oscillator over a 10,000/1 frequency
range.
Input: 1 Volt/dial division.
Input impedance: 25KQ.
Linearity: 2%.
Input frequency: DC to >10kHz.
Sweep ramp generator:
Output voltage: 0 to >+10 Volts with a continuously
adjustable upper limit from +0.6 to +10 Volts using the
variable symmetry control in the OFF mode.
Ramp duration : >4 sec to 65m sec approximately.
Continuously adjustable by the OFFSET control in the OFF
position.
When coupled into the FM socket,the Function Generator will
sweep from the frequency selected by the dial up to the
frequency set by the ramp amplitude control. An automatic
circuit prevents the sweep exceeding the dial range.
Horizontal drive to oscilloscope or recorder is also taken
from ramp output via the voltage amplifier (see 2.14) to set
drive voltage and polarity required.
