4 - 16. RESOLUTION BANDWIDTH SELECTIVITY
SPECIFICATION:
60-dB/3-dB resolution bandwidth ratio: < 15: 1
DESCRIPTION:
The 60
- dB bandwidth is measured for all resolution bandwidths. The 60 - to 3 - dB resolution bandwidth ratio
(shape factor) is then computed for each bandwidth by dividing the 3
- dB value (from the Resolution Bandwidth
Accuracy test) into the 60
- dB value.
In the 30
- , lo-, 3 - , and 1 - kHz bandwidths, a 21.4 - MHz signal (final IF) is injected into Bandwidth Filter No. 1
Assembly
All to provide the stability required for the measurement of narrow resolution bandwidths.

In the following procedure, the plug - in must be removed from the display
mainframe and connected through the extender cable assembly. Be very
careful; the energy at some points in the instrument will, if contacted, cause
personal injury. This test should be performed only by a skilled person who
knows the hazard involved.
