14. the standard HP 8514B includes four RF to IF converters to measure all four S parameters without reconnecting the DUT two 90 dB programmable step attenuators for changing in 10 dB steps the incident power level at both ports two bias tees for applying external dc bias to both test port center conductors In the High Forward Dynamic Range Configuration option 003 the Port 2 coupler is reversed to optimize dynamic range in the forward measurement direction Because the b2 sampler is connected to the coupler throughpath instead of the coupled arm there is less isolation between the b2 sampler and Port 2 and the b2 power level will be higher than b1 This configuration is better for wide dynamic range or reciprocal devices or components like filters cables or antennas where S is generally not measured However as a result of the lower isolation between the test port and the sampler sampler bounce appearing as an occasional spurious response related to the VTO frequency can be noticeable in this asymmetrical test set The HP 8512A reflection transmission test set uses one coupler for signal separation The standard HP 8512A has three RF to IF converters for making reflection 511 and transmission 521 measurements no step attenuators to internally change the incident power level nobias tees to apply external DC bias to the test port center conductors HP 8514B and 8512A Test Sets General Informat
