ZISO-Z101: MMCX, 1.5x, 8 V (RMS), ±45 V (peak)
The MMCX connector has the best signal fidelity with an excellent CMRR at high bandwidths. For measurements with < 700 ps rise time, consider using test points with an MMCX connector. The lower attenuation for the probe tip can only support limited input and offset range but is important for measurements that require high sensitivity and lower noise levels.
The probe head is designed with highest isolation in mind to minimize exposed metal during operation. The probe tips are designed with isolation caps that indicate the safe handling zone. This allows R&S ZISO-Z301 and R&S®ZISO-Z302 isolated passive probes to be used for quick access to measurement locations when debugging.
Another innovation on the R&S ZISO is the safe attach feature on the probe tips. The quick lever allows the tips to be secured quickly and safely to the probe head without the need of additional tools such as wrenches or having to manually screw in the tips. Over-tightening of the SMA connector could eventually damage the contact and degrade the signal and isolation performance. Limiting direct contact with the metal conductor helps prevent electrostatic discharge (ESD) on the sensitive probe tips and heads.
