Precision TP300

TP300 Precision Positioner

To support the smallest geometry and highest precision for microwave and wafer probing, the compact TP300 Precision Positioner is designed with the most precise components and built with highest quality; at the same time, it offers the most competitive price in the industry. The extra large adjustment screw for y-axis ensures ease of control of the microprobe.


  • Travel Range X, Y & Z: 20 mm with 500 μm/turn (50 TPI)
  • Z-axis coarse adjustment: 8 mm/step (6 steps)
  • Planarization Rotation: ±10° with 2.5°/rev
  • Resolution: 5 micron
  • Weight: 1165 grams/41.1 oz
  • Probe Holder: Removable microprobe holder
  • Base: Lockable Magnet
TP300 Probe


  • Most precise and stable control
  • Compatible with most microprobes
  • Availability: Contact PacketMicro
  • For new customers and existing customers to start new projects, PacketMicro recommends customers to use TP250. TP250 has the same features and capability as TP300 at a little lower price.

In addition to offering TP300 to hold microprobes, PacketMicro has a special adapter PMA01 (PacketMicro Probe Adapter), to hold our rugged S-Probes and D-Probes. (View S-Probe and D-Probe pages.)

The S-Probe, D-Probe and microprobe combination offers engineers the option to use S-Probe or D-Probe (for differential signals) for slower speed probing or probing with components, and reserve the fragile, expensive (and easy to break) microprobes for only the most critical measurements. The price for the adapter is $100 each.

We recommend GGB and Cascade microprobes for accurate S21 measurement of PCB traces.
