Information
                                    The Hewlett-Packard Model 606A is a general-purpose signal
Generator with a frequency range of 50 kHz to 65 MHz. The
instrument has a direct reading frequency dial calibrated to
an accuracy of 1%. Output is held constant within ± 1 dB and
is continuously adjustable from.01 microvolt to 3 volts into
a 50 ohm resistive load. An internal crystal Calibrator
provides check points at 100 kHz and 1 MHz intervals with an
error of less than 0.01%. A front-panel meter accurately
indicates the percent amplitude modulation for frequencies
within the modulation bandwidth of the signal Generator.

The Model 606A has a highly refined amplitude modulation
system which allows modulation up to 90% with low distortion
and incidental FM. This feature makes possible precision
distortion checks of receivers from antenna to output. The
instrument can be internally modulated at 400- or 1000 Hz.
It can be externally modulated from dc to 20kHz or more,
depending on RF frequency in use. Complex waveforms, square
waves, and dc voltages may be used to modulate the Model
606A for testing and evaluating filters, networks,
amplifiers, and receivers.

DIFFERENCES BETWEEN INSTRUMENTS.

The Model 606A carries a five-digit serial number with a
three-digit prefix (000-00000). The prefix changes only when
a change is made in the instrument. The prefix, then, is an
identifier, and it appears on the title page of this manual
to indicate to which instrument this manual directly
applies. A supplement may be included with this manual to
indicate the necessary changes to be made in the manual to
make it apply directly to instruments which carry a
different serial number prefix.
