Pasternack has introduced a new line of semi-rigid test probes designed to assist in testing microwave circuits. The test probes are offered in three different diameters of semi-rigid coax including 0.51mm, 0.86mm and 1.19mm. All test probe cable assemblies are 100 per cent RF tested to ensure the cable assemblies operate to a maximum frequency of 6 GHz and to also ensure that the SMA connector meets the 1:35:1 VSWR specification prior to shipping, according to the company. These assemblies come in 3, 6, 9 and 12-inch lengths and are designed to fit a variety of trace widths and applications. The probes are also terminated with female SMA connectors.
