FormFactor - Cascade WPH Probe - Multi-contact DC probe with full-radius needles
- Full-radius, nickel-plated tungsten needles
- Power bypass inductance: 16 nH
- Supports collinear and non-standard needle configurations
- Support up to a maximum of 12 ceramic blades DC needles / contacts
- Ideal for probing the entire circuit for functional test
- DC probes can provide power or slow logic to circuit under test
The WPH probes feature up to 12 ceramic-bladed, nickel-plated, tungsten needles with a 2 x 12 square pin cable interface. The circuit board has been laid out such that both series and shunt components can be added to the signal path of each needle.

The Low Frequency Tuner (LFT) is a unique product technology using M algorithms for low frequency wideband tuning. Three or more cascaded tuning sections use series transmission cables and parallel rotary capacitors. The length of the cables and number of tuning sections are optimized for maximum tuning range over a given bandwidth. HLFT tuners use 6 tuning sections allowing second harmonic frequency tuning.
