PERFORMANCE TESTS
4-1 6. RESOLUTION BANDWIDTH SELECTIVITY (Cont'd)
Set RESOLUTION BW to 300 kHz, leaving FREQ SPAN/DIV set to 0. Repeat steps 14 through 18.
kHz
Set RESOLUTION BW to 1 MHz, leaving FREQ
SPAWDIV set to 0. Repeat steps 14 through 18.
MHz
Select ALT IF (switch pushed in). Set RESOLUTION BW to
3 MHz, leaving FREQ SPAN/DIV set to 0.
Repeat steps 14 through 18.
MHz
Return ALT IF switch to OFF position. With
RESOLUTlON BW still in 3 MHz and FREQ SPAN/DIV
set to 0, repeat steps 14 through 18.
MHz
In Table 4
- 4, record 3 - dB bandwidths computed in 4 - 15 Resolution Bandwidth Accuracy test.
In Table 4
- 4, record 60 - dB bandwidths recorded in this procedure.
For each resolution bandwidth, divide 60
- dB bandwidth by 3 - dB bandwidth to obtain Resolution Band -
width Ratio. Each ratio should be less than 15: 1.
