5.2.5
Resolution Bandwidth Accuracy and Selectivity
This test measures the 3 dB down of RBW accuracy and selectivity.
Selectivity is specified the 3 dB and the 60 dB down bandwidth of RBW.
RBW 30 Hz to 300 Hz are the option, if the unit is installed OPT27, perform verification.
Specification:
RBW Range 1 kHz to 3 MHz (1,3,10 sequence), 30 Hz to 300 Hz (OPT27)
Accuracy:
±
25% (RBW 3 MHz)
±
20% (RBW 1 kHz to 1 MHz)
±
20% (RBW 30 Hz to 300 Hz OPT27)
