PMM SHC 1, SHC 1/1000, SHC 2 Voltage Probes

PMM SHC 1, SHC 1/1000, SHC 2 Voltage Probes

When LISN (Line Impedance Stabilization Network) are not applicable to EMI conducted test because the current flowing is too high, the conducted interferences are measured by means of a high impedance voltage probe, according to C.I.S.P.R 16-1 subclause 12.2.

The passive probes are designed to comply with CISPR 16-1 regulation and thus include a blocking capacitor to decouple the measured signal from any AC supply voltage which may be present on the line under test, they have a total internal resistance between line and earth of more than 1500 ohm.

Features:
• Insertion loss: SHC-1 35 dB (typical), SHC-1/1000 35 dB (typical), SHC-2 30 dB (typical)
• Input impedance: over 1500 Ohm
• Complete 3 axis system with switching unit
• Input capacity :  less than 10 pF
• Frequency range : 9 kHz ÷ 30 MHz
• Max permissible input operating voltage: SHC-1 300 Volt AC, SHC-2 300 Volt AC, SHC-1/1000 1000 Volt AC
RF output: BNC male
• Rated temperature: 0 to + 45 C
• Storage temperature: - 25 to + 70 C
