16. Resolution Bandwidth Switching
Uncertainty
To measure the resolution bandwidth switching uncertainty an
amplitude reference is taken with the resolution bandwidth set to
1 kHz using the marker delta function. The resolution bandwidth is
changed to settings between 5 MHz and 1 Hz, as applicable, and the
amplitude variation is measured at each setting and compared to the
specification. The span is changed as necessary to maintain
approximately the same aspect ratio.
The related adjustment for this performance test is “IF Amplitude.”
