PERFORMANCE TESTS
4-16. RESOLUTION BANDWIDTH SELECTIVITY
SPECIFICATION:
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 A l l to provide the stability required for the measurement of narrow resolution bandwidths.
D l SPLAY
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.
