Models 101/102/103 Function Generators and the
104/105 Voltage Controlled Generators are semi-precision
sources of waveforms from servo to video frequencies. These
units are extremely rugged, completely transistorized
portable packages. Extremely clean and stable waveform
signals from .008 cps to lMc in the 101/102/103 and from
.0015 cps to lMc in the 104/105 make all 5 generators
versatile, general purpose pieces of equipment for the
laboratory or the field.
The model 101
offers square waves and triangle waves. The
Models 102 and 104 offer square, triangle, and sine waves.
Models 101, 102 and 104 are available with three power
supply options: AC line power, dry cell battery, and
rechargeable nickel cadmium batteries with built-in charger.
Models 103 and 105 provide 30V p-p triangle, sine or square
waves into a 600 ohm load. Models 103 and 105 are available
in the AC power version only.
The 104 and 105 have the capability of having the dial
electrically changed by application of an external voltage
without physical movement of the dial. As such, they are
truly general purpose F.M. modulators.
The wide frequency range of all five models makes them
useful for low frequency applications such as servo and
electro-mechanical systems, as well as audio or even video
work. Complex oscilloscopes may be completely
checked out for proper operation in the field or on the
repair bench with this single, versatile, and portable
instrument. The VCG is capable of sweep testing I.F. Strips,
low frequency filters or F.M. of a servo. In addition, with
proper inputs, it is possible to F.M. or sweep, a triangle,
sine, or square wave. The very fast rise and fall times are
ample for triggering high speed computer circuitry. Battery
versions allow complete isolation from the power line and
ground. This is particularly useful in any low level or wide
Models 101/102/103 have three outputs with independent
amplitude controls: (1) 10V p-p max. square wave at 600 ohm
output impedance; (2) IV p-p square wave at 50 ohm output
impedance, rise and fall time less than 5 nanoseconds; (3)
triangle wave 5V p-p max., Model
102 triangle wave 5V p-p or 2V rms sine wave, Model 103
triangle, sine,or square waves 30V p-p max. into a 600 ohm load.
Models 104 and 105 have two outputs with independent
amplitude controls: (1) IV p-p square wave at 50 ohm output
impedance; (2) Model 104: triangle wave 5V p-p max., sine
wave at 2V rms, or square wave 10V p-p max. at 600 ohm
output impedance; Model 105: triangle, sine or square wave
30V p-p max. into a 600 ohm load. The VCG input has an
attenuator control which provides a minimum input impedance
of 10K ohm. An input of 4.75 volts total will provide a 20:1
frequency range which is equivalent to full spread of the
dial. The VCG input attenuator may be driven with any
vQltage up to 100V without damage to the instrument.
