The '''Tektronix SD-14 High Impedance Probe Sampler''' is a dual-channel, 3 GHz probe sampler designed for high-impedance (100 kΩ) signal acquisition.


From Tektronix' site:
It consists of two samplers, each attached at the end of a 1-meter cable. Applications include high-speed device characterization such as ECL, CMOS, ACL and GaAs testing.  
<blockquote>
Option 01 adds a longer probe tip, two probe-to-board adapters, and two probe-to-SMB adapters. These ease probing of plated holes (as found in Outboards for IC testers) and semi-permanent connections.
The SD14 is a dual-channel, 3 GHz probe sampler designed for high-impedance signal acquisition where a 50 Ohm acquisition system is not the optimal solution. The SD14 is ideal for high-speed device characterization such as ECL, CMOS, ACL and GaAs testing. The 100 kilohm input impedance and 0.5 pF capacitance results in very low loading of the device under test. The 7 V dynamic range and ±3.5 V offset range, makes the SD14 suitable for testing all digital logic families as well as most analog circuits.

The Tektronix SD-14 High Impedance Probe Sampler is a dual-channel, 3 GHz probe sampler designed for high-impedance (100 kΩ) signal acquisition.

It consists of two samplers, each attached at the end of a 1-meter cable. Applications include high-speed device characterization such as ECL, CMOS, ACL and GaAs testing. Option 01 adds a longer probe tip, two probe-to-board adapters, and two probe-to-SMB adapters. These ease probing of plated holes (as found in Outboards for IC testers) and semi-permanent connections.

In conjunction with the 11801C and SM-11 multi-channel unit, it is possible to configure up to 136 channels of high-impedance acquisition with accuracy approaching 140 ps.
