Description: RF Signal Generator
Informations:
                                    Continuous coverage from 100 kHz to 216 MHz in seven
frequency bands (54 MHz to 216 MHz signals use harmonic
output). No gaps in coverage. Covers AM broadcast band, FM
broadcast band, amateur, short wave and two-way
communications bands, and all VHF television channels, plus
all i-f frequencies.

Uses 18 semiconductor devices for
all the advantages of solid state
technology; reliability, ruggedness,
instant warm-up, low power
consumption, no high voltage.
light weight and compactness.

Oscillators and attenuators are
shielded to reduce "spray" radiation;
a necessity when testing
and aligning high sensitivity
receivers.

Sinusoidal rf output signal has
very low distortion on fundamental
output ranges to 54 MHz.

A 6.1 gear reduction ratio between
the tuning knob and the
dial allows the dial to be easily
and accurately set.

A large circular two-color dial (15-
inch circumference with seven
separate frequency scales provides
easy, accurate direct frequency readings.

Key frequencies and frequency
ranges are identified: Broadcast
receiver i-f; FM i-f; TV i-f sound
and video frequencies; FM band;
VHF TV Video Carrier frequencies
for all 12 VHF channels.

A carrier level meter and step attenuators provide
accurately calibrated output level measurement from —106 dB
to +2 dB (0.5 uV to 126,000 uV) when using the 50-ohm
terminated cable that is supplied with the instrument.

A modulation percentage meter
and modulation level adjustment
permit calibrated modulation from
0 to 50%, with higher uncalibrated
levels (up to 100%) possible.

A built-in crystal controlled oscillator,
"zero beat" circuit and adjustable
cursor marker provide
dial accuracy of 0.1%.

Internal 400 Hz oscillator provides
low distortion modulation
voltage.

The output of the 400-Hz oscillator
is available at the external
modulation jacks for use as an
audio test signal. Thus, the signal
generator can be used for
complete testing of both the rf
and audio sections of a receiver.

The level is fully adjustable from
0 to 1.25 volts rms.
Lets you tell at a glance whether
instrument is on or off.

Controls and indicators are "operator
designed". Related controls are grouped,
lettering is easy to read and "explains"
rather than confuses. Simplified
control layout for calibration accuracy eliminates complicated
conversion tables and graphs for
precision frequency and output
level settings.
