RESOLUTION BANDWIDTH SELECTIVITY (Cont'd)
4-16.
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.
6. Calculate and record resolution bandwidth at 60-dB points (difference between frequencies recorded in
steps 4 and 5).
7. Set RESOLUTION BW to 3 kHz, leaving FREQ SPAN/DIV set to 0. Repeat steps 3 through 6.
8. Set RESOLUTION BW to 10 kHz, leaving FREQ SPAN/DIV set to 0. Repeat steps 3 through 6.
9. Set RESOLUTION BW to 30 kHz, leaving FREQ SPAN/DIV set to 0. Repeat steps 3 through 6.
10. Disconnect signal generator from A16J3. Set the display's LINE power to OFF and remove extender cable
assembly. Install plug-in in mainframe and set LINE power to ON.
11. Set equipment controls as follows:
