4 .2 FREQUENCY RANGE AND RESOLUTION TEST
SPECIFICATION
4-2
Range
1 MHz to 520 MHz selectable in 1 kHz steps .
Resolution
1 kHz
TABLE 4-1 .
(Cont'd)
METHOD A frequency counter is used to measure the frequency range
and the frequency resolution . All frequencies in CW and AM
modes between 1 and 520 MHz are selected by front-panel lever/
indicator switches . Each of the digits of the frequency se-
lector (a total of 56) will be tested .
The 0 through 9 kHz
digits provide 1 kHz resolution .
