ACCURACY
Any signal generator is designed as a convenient and controllable source of modulated or unmod ­
ulated signals. No signal generator is designed as a frequency standard. Expensive standard
signal generators have fairly accurate (3 to 20%) attenuators which control the output voltage
and the calibration accuracy is rarely closer than 1%. The Heathkit Signal Generator may be
expected to fall within 2 to 3% of the frequency calibration, which is quite satisfactory for ser ­
vice work and alignment. In receiver adjustment, the frequency at which the particular adjust ­
ment is made is rarely critical but the adjustment itself for maximum signal output from the
On the other end of the shield cable, the outer insulation is cut back about 4 " and the cable pre ­
pared as shown in Figure 12. Solder alligator clips to both the inner conductor and the shield
braid.
The test lead is assembled as shown in Figure 11. One end of the shielded cable is connected to
the shielded plug; the other end has alligator clips mounted on it for connection to the equipment
under test. First, remove the spring cable guard from the connector plug by loosening the
screw in the side of the plug. Slide this spring over the shielded cable, with the small end of
the spring toward the end that is to be connected to the plug. The outside insulation on the cable
is then cut back for a length of about 3/4", then flare the shield braiding at the end of the cable
so that it may be pushed back over the small end of the spring cable guard. The inner connector
is then stripped for a length of approximately 1/8". The assembly at this point is slid back into
the connector so that the inner coaxial wire passes through the rivet in the insulated end of the
connector, the cable guard with the shielded braid flared over the end is pushed back into the
connector and the screw tightened to hold it in place. Solder the inner connector.
