High-Temperature Probe

Note: The original version of this probe is also known as the 85070A Probe. This probe is almost identical to the High Temperature probe. The way to distinguish these two probes is that the glass seal on the 85070A probe looks clear and the glass seal on the High Temperature probe is a translucent milky white.

Frequency Range : 200 MHz to 20 GHz with network analyzer, or 10MHz to 3GHz with impedance analyzer (normal) . Maximum limited by MUT properties, where fmax = GHz
Temperature Range: -40 ° C to +200 ° C
Dielectric constant: εr ‘ = εr ‘ +- 5% | εr *|
Loss Factor: εr “ = εr “ +- 5% | εr *|
Repeatability and resolution: Two to four times better than accuracy
Sample Requirements:
1. Material is ‘infinite’ in size, non-magnetic μ _r* = 1), isotropic (uniform orientation and homogeneous (uniform composition). Solids have a single, smooth, flat surface with gap-free contact at the probe face.
  
  Diameter: >20 mm
  
  Thickness:
  
  Granule size: < 0.3 mm
