FastEdge™PS
PHASE STABLE RF CABLE ASSEMBLIES
overview
FastEdge™ PS RF cable assemblies feature enhanced phase and amplitude stability with flexure without sacrificing flexibility. They are optimized for laboratory and production test environments that require precise and repeatable measurements. The flexibility of FastEdge™ PS cables reduces mechanical stresses on the device under test (DUT) as compared to phase stable assemblies from other manufacturers.
Typical Electrical Performance
Measurement Quality
The excellent phase and amplitude stability of FastEdge™ PS RF Cable Assemblies ensures accurate and repeatable measurements on the DUT (device under test). All cable assemblies are 100% tested to assure S-parameters and stability with flexure meet or exceed their specified performance.
1 SBT sought to better simulate the actual use model of RF cables utilized in the test and measurement market. In actual use, the RF cable is calibrated or normalized in one position then the distal end is disconnected and reconnected after moving the cable into a new position. SBT’s quality inspection procedures specify that upon normalization, the cable is disconnected from port 2 of the VNA, wrapped 360° around a 4.5” diameter mandrel and reconnected to port 2 of the VNA; maximum phase and IL change is measured at this point. Therefore phase and insertion loss stability is measured in transmission rather than reflection which simulates actual use more closely. SBT utilizes one wrap in the preferred direction of cable lay since RF cables have a preferred direction in which they coil; normally the user will follow the natural direction of lay rather than forcing the cable to bend or coil “unnaturally”.
Phase/Time Delay Matching
Upon request, phase or time delay matching can be specified for FastEdge™ PS RF cable assemblies. According to the user’s requirements for their application, cable assemblies may be specified to meet absolute or relative matching values.
- Absolute matching is when one or more cable assemblies conform to a specific time delay target value within some tolerance (±) value.
- Relative or Differential matching is when the time delays of two or more assemblies conform to a specified delay range. Relative or differential matching ensures consistent matching within a set of cables, but an assembly from one set may not necessarily be matched with cable assemblies in another set. Swift Bridge Technologies addresses this by uniquely labeling the cables within a matched pair or set. Time delay matching within 1 ps available.
