500 MHz high-impedance passive probe 10:1 with BNC

The TA133 is a high-impedance passive probe with 500 MHz bandwidth. It is designed for use with oscilloscopes with a 1 MΩ input impedance and has a fixed attenuation of 10:1. The TA133 has been compensated to ensure optimal performance with the PicoScope 6404 oscilloscopes.

The compact design of this high-performance probe means there is only 2.5 mm housing diameter at the probe tip compared to the conventional 5 mm housing, making it easier to see the device under test and making it ideal for measurements of SMT components.

Each TA133 probe is supplied with the following accessories and spares:

  • 1 x Coding rings (set) 3x4 colours
  • 1 x Ground blade 2.5
  • 1 x Ground lead 15 cm
  • 1 x Ground spring 2.5
  • 1 x IC-Cap 2.5 0.5 mm pitch; green
  • 1 x IC-Cap 2.5 0.65 mm pitch; blue
  • 1 x IC Cap 2.5 0.8 mm pitch; grey
  • 1 x IC Cap 2.5 1.0 mm pitch; brown
  • 1 x IC Cap 2.5 1.27 mm pitch; black
  • 1 x Insulating cap
  • 2 x Self-adhesive Cu pad 2 x 2 cm
  • 1 x Solid tip CuBe 0.5 mm
  • 1 x Spring tip gold plated 0.5 mm
  • 1 x Sprung hook
  • 1 x Trim tool
  • 1 x PCB adaptor kit
