                                    The Model 147 HF Sweep Generator is a precision 0.0005 Hz to
10 MHz source of sine, triangle, square, positive pulse,
and negative pulse waveforms, each with variable amplitude,
dc offset, and symmetry. Frequency range selection is
provided in 10 decades, with a 3 digit LED readout and
vernier control which permits accurate adjustment to the
least significant digit of the readout. The 31^ digit
readout is 3 digits plus λ fourth (tin* most significant)
digit of 0 or I. DC voltage output is also selectable with
an adjustable range of * 10 Vdc into .in open circuit Vdc
into with 150 rnA short circuit current.
Maximum output amplitude is 30 V p-p into an open circuit
(15 V p-p into 50Ω) with a 2O dB calibrated step attenuator
and a dB vernier attenuator (80 dB overall) allowing signal
levels as low as 1.5 mV p-p. Both the output waveform and
the dc offset are attenuated by the 60 dB calibrated step
attenuator. Maximum and minimum output peak voltages are
displayed on the 3Vi digit LED readout and are accurate to
the specification when the output has been properly
terminated with 50Ω load.
The Model 147 has six operational modes (continuous,
triggered, gated, continuous sweep, triggered sweep, and
sweep and hold) plus tone burst capability. The main output
can be internally swept over approximately a 1000:1 ratio at
sweep times from 10 (J.s to 100 s, or it can be frequency
modulated, dc programmed, or externally swept over a greater
than 1000:1 ratio by applying an external
control signal to the front panel VCG IN connector. A

single cycle of output, or one can be obtained by manuel
trigger or an external trigger siqnal applied to The front
panel TRIG IN connector.
In addition to the 50Ω main output and sync output, the
Model 147 also has sweep and generator control voltage (GCV)
outputs. When the main output is not internally swept (i.e.,
operating in continuous, triggered, or gated modes without
sweeping), the fixed amplitude sawtooth output of the
internal sweep generator appears at the SWP/GCV OUT
connector. When the main output is internally swept, an
output voltage proportional to the instantaneous frequency
of the main generator will appear at the SWP/GCV OUT
connector. This GCV output can be used to
drive X-Y recorders or the vertical and horizontal
deflection circuits of oscilloscopes, video monitors, etc.
Varying the triangle symmetry produces a sawtooth signal
with a rise o* fall time as fast as 50 ns .it a recurring
rate of up to 1 MHz Pulse outputs as narrow as 50 ns (duty
cycles from 19:1 to 1:19) with repetition rates as high as 1
MHz c,m be generated in either polarity. Even the sine wave
symmetry may be varied over this 1:19 to 19:1 range if
desired When the output symmetry is not 1:1, the frequency
range setting is divided L>y approximately 10; however, the
actual output frequency is displayed on the LED readout.
With this instrument it is possible to internally or
externally sweep the output frequency, select the output
symmetry desired, and manually vary the dc offset. The
output frequency, positive peak amplitude and negative peak
amplitude are displayed on a digital readout. DC offset or
dc output voltage can be set by digital readout. These
capabilities coupled with the variety of waveforms available
and precision output amplitude control make the Model 147 an
extremely versatile instrument.

This manual provides descriptive material and instructions
for the installation, operation
maintenance, and repair of this instrument. Wavetek’s
product improvement program ensures
that the latest electronic developments are incorporated in
all Wavetek instruments by the
addition of circuit and component changes as rapidly as
development and testing permit
Due to the time required to document and print instruction
manuals, it is not always possible
to incorporate the more recent changes in the released
manual. In this case, data will be found
on engineering change sheets at the rear of the manual.
