Tektronix MMCX10X — Technical facts

The Tektronix MMCX10X is an IsoVu MMCX probe sensor tip, 10× attenuation, rated for a maximum non‑destructive differential voltage of 250 Vpk, with a usable differential input range of ±50 V, offset capability to ±200 V, and designed for use with Tektronix IsoVu/TIVP probe systems.

Model and system compatibility
Part number: MMCX10X (TIVPMX10X); family: Tektronix IsoVu / TIVP series probe sensor tips; interface: MMCX precision coaxial tip intended for use with Tektronix IsoVu active probe heads and compatible probe amplifiers.

Electrical specifications

• Attenuation: 10×.
• Maximum non‑destructive differential voltage: 250 Vpk.
• Linear differential input voltage range: ±50 V.
• Offset (common‑mode) range: ±200 V.
• Differential input impedance: 10 MΩ.
• Equivalent input capacitance: ≈2.8 pF (tip contribution).

Performance characteristics

• Common‑mode rejection ratio (CMRR): ~160 dB at DC, ~115 dB at 1 MHz, ~92 dB at 100 MHz, ~90 dB at 200 MHz, ~85 dB at 500 MHz, and ~80 dB at 1 GHz (system CMRR figures with IsoVu probe head and MMCX tip).
• System noise (rms): example values reported for IsoVu systems with this tip: ±20 mV range (most sensitive): 4.3 mVrms; ±320 mV range: 14.6 mVrms; ±5 V range (widest): 480 mVrms (noise depends on amplifier range and system configuration).

Mechanical and handling

• Connector/type: MMCX precision tip; designed for minimal lead length and optimal bandwidth/CMRR when mated to IsoVu probe heads.
• Use notes: tip is a replaceable sensor accessory for IsoVu probes; follow Tektronix torque and handling guidelines for MMCX mating cycles and avoid excessive mechanical stress to preserve high‑frequency performance and connector life.
