A plurality of calibration structures facilitate calibration of a probing system that includes a differential signal probe having a linear array of probe tips.
We claim: 1. A probe calibration structure for calibrating a probe having five spaced apart probe tips, said five probe tips arranged in a linear array and operable to communicate a bias to a device under test from a centrally located probe tip and to communicate plural components of each of two ra
We claim: 1. A probe calibration structure for calibrating a probe having five spaced apart probe tips, said five probe tips arranged in a linear array and operable to communicate a bias to a device under test from a centrally located probe tip and to communicate plural components of each of two radio frequency, differential signals with said device under test with pairs of probe tips disposed to either side of said centrally located probe tip, said probe calibration structure comprising: (a) a substrate having a surface; and (b) a substantially linear array of five contact regions and no more than five contact regions on said surface of said substrate, said five contact regions arranged to spatially correspond to said probe tips of said linear array of five probe tips of a probe to be calibrated, each contact region spaced immediately apart from at least one other contact region, electrically isolated from each other contact region and engageable by a respective one of said five probe tips, a bias conducted by said centrally located probe tip to a centrally located contact region of said array of contract regions and one component of a pair of radio frequency, differential signals conducted to each contact region other than the centrally located contact region by respective contact tips. 2. A probe calibration structure for calibrating a probe having seven spaced apart probe tips, said seven probe tips arranged in a linear array and operable to communicate a bias to a device under test from a centrally located probe tip and from a probe tip at each extreme of said linear array and to communicate plural components of each of two radio frequency, differential signals with said device under test with pairs of probe tips disposed to either side of said centrally located probe tip, said probe calibration structure comprising: (a) a substrate having a surface; and (b) a substantially linear array of seven contact regions and no more than seven contact regions on said surface of said substrate, said seven contact regions arranged to spatially correspond to said probe tips of said linear array of seven probe tips of a probe to be calibrated, each contact region spaced immediately apart from at least one other contact region, electrically isolated from each other contact region and engageable by a respective one of said seven probe tips, a bias conducted by said centrally located probe tip to a centrally located contact region of said array of contract regions and conducted by said probe tip at each end of said array of probe tips to a respective contact region at each end of said array of contact regions and one component of a pair of radio frequency, differential signals conducted to each contact region other than the centrally located contact region and the contact region at each end of said linear array by respective contact tips.
