Test Description
To measure the resolution-bandwidth switching uncertainty, an amplitude reference is
taken with the resolution bandwidth set to 1 kHz. The resolution bandwidth is changed to
settings between 5 MHz and 3 kHz and the amplitude variation is measured at each
setting using the marker delta function and compared to the specification. The span is
changed as necessary to maintain approximately the same aspect ratio.
No equipment required for analyzer models E4401B and E4411B.
Resolution Bandwidth Minimum (dB) Maximum (dB)

10 kHz –0.3 dB 0.3 dB
30 kHz –0.3 dB 0.3 dB
100 kHz –0.3 dB 0.3 dB
300 kHz –0.3 dB 0.3 dB
1 MHz –0.3 dB 0.3 dB
3 MHz –0.3 dB 0.3 dB
5 MHz –0.6 dB 0.6 dB
