The model 4001A is an economy function
generator with the ability to provide linear
and logarithmic frequency sweeps -- a
feature usually not seen at this price point.
This feature is useful for the frequency
characterization of system behavior or the
discovery of resonances.
Model 4003A is similar to the 4001A, but
provides digital frequency setting and a
20 MHz frequency counter for external signals
with 100 mV sensitivity at a surprisingly low
price.
These analog function generators offer
familiar controls, stable output, and reliable
operation at budget-saving price points.
While DDS generators have eclipsed analog
generators at the high end, these analog
generators are the workhorses of industry,
education, and hobbyists. They are widely
used for characterizing and troubleshooting
electrical circuits.

Note: While only the 4040A offers FM modulation,
all units except the 4001A have a VCG (voltage
controlled generator) input that can simulate FM
modulation when driven by a modulating signal. In
addition, providing a ramp signal to this input can
effectively sweep the generator's output
frequency. On generators with sweep, the VCG
jack provides a DC signal proportional to the
instantaneous frequency, which can be useful for
driving XY plotters or scope displays.
The model 4017A is a 10 MHz sweep
function generator with a 5 digit LED display,
linear/log sweep, variable duty cycle and DC
offset.
Models 4011A and 4012A are popular 5 MHz
generators for general bench and lab use with
an ideal mixture of features at a compelling
price. The 4012A is identical to the 4011A,
but with a sweep function added.

The model 4040A is an analog generator with
AM/FM modulation (internal or external),
linear/log sweep, and burst capability.
Includes a 5 digit 30 MHz frequency counter
with 30 mV sensitivity.
