    Operation Operating Hints RF Port Voltage Standing Wave Ratio (VSWR) Effects As with most bandpass filters, the magnetically tunable Barrium-Ferrite bandpass filter of the 11974 is reflective out of its passband. In addition, the 11974 does not have a programmable RF port attenuator to improve the VSWR in band or out of band. This may cause measurement errors when testing VSWR sensitive DUTs outside of their operating frequency range.
