TTL/CMOS OUTPUT
The TTL/CMOS output jack provides a fast rise time square
wave output. Either a fixed TTL or a variable CMOS output
level is available. The output is positive with respect to ground
and can be used as an external sync pulse for oscilloscopes or
as a variable frequency signal source for exercising logic
circuits. Because of the fast rise time of this output, cable
length should be minimized to limit ringing and overshoot.
VOLTAGE CONTROLLED FREQUENCY OPERATION
The Model 4010A can be operated as a voltage-controlled generator
by using an external control voltage applied to the VCG INPUT
jack. The externally applied voltage will vary the frequency which is
preselected by the range switches and the frequency controls.
Applying approximately +l0 V with the FREQUENCY control at
full clockwise decreases the output frequency by about 100 times (a
100:1 ratio).

is output at the TTL/CMOS jack. Select a CMOS signal by
engaging the CMOS LEVEL switch and adjust the level of
the signal by rotating the CMOS LEVEL control (8).
Set the starting frequency with the FREQUENCY control.
Apply a positive DC voltage to the VCG INPUT jack (9) to
decrease the frequency. A voltage from 0 to +10 V will
cause the frequency to decrease by a factor of 100 if the
FREQUENCY control is set at maximum CW rotation.
For example, if the starting frequency is 200 kHz, applying
+10 V will change the output frequency to 2 kHz.

OUTPUT PROTECTION CONSIDERATIONS
signal injection point. Excessive voltage at the point of signal
injection of the function generator can cause internal damage.
Under normal operation, the generator output should never be
connected to an external voltage other than low dc values that
can be matched with the DC OFFSET control. The Model
4010A is overload protected so that shorting the output, even
continuously, will not cause damage. A fuse has been added in
series with the OUTPUT jack to help protect the instrument
from damage by connection to excessive external voltage.
connecting the output of the function generator to a voltage in
the equipment under test. The following protective measures are
strongly recommended:
3. To operate the function generator as a sweep generator,
4. Specific frequencies can be selected by applying a fixed

Use care when connecting the function generator output to a

apply a positive going ramp signal to the VCG INPUT
jack. As the ramp voltage increases, the frequency
decreases. The rate of sweep can be adjusted by varying
the frequency of the ramp signal.

base of a transistor, a logic input of a gate, etc.). The
voltage at valid signal injection points is rarely high
enough to damage the instrument.
