PERFORMANCE TESTS
4 - 16. RESOLUTION BANDWIDTH SELECTIVITY (Cont'd)
5.
Tune signal generator in direction opposite to that of step 4 until trace peaks (top graticule line) and then
drops to 2 divisions above graticule baseline. Record signal generator frequency.
MHz
6.
Calculate and record resolution bandwidth at 60
- dB points (difference between frequencies recorded in
steps
4 and 5).
kHz
7.
Set RESOLUTION BW to 3 kHz, leaving FREQ SPAN/DIV set to 0. Repeat steps 3 through 6.
kHz
8. Set RESOLUTION BW to 10 kHz, leaving FREQ SPAN/DIV set to 0. Repeat steps 3 through 6.
kHz
9. Set RESOLUTION BW to 30 kHz, leaving FREQ SPAN/DIV set to 0. Repeat steps 3 through 6.
kHz
10. Disconnect signal generator from
