Rohde & Schwarz ZISO-Z202 Sq Pin Tip, 25X, +/-750Vrms, +/-1kV Peak, 10Mohm, 3.5pF, .3m, ZISO Series

Rohde & Schwarz ZISO Series - ZISO-Z202 SQPIN Tip

ZISO-Z202: Square Pin (SQPIN), 25x, ±750 V (RMS), 2.54 mm pitch

Even though the square pin can be easily accessed as a test point during design, realize that the proximity may not meet creepage requirements and can lead to arcing. The R&S ZISO-Z202 square pins can measure up to ±750 V and provide the same ±750 V offset range. As mentioned earlier, the CMRR performance and voltage range degrades as bandwidth increases.

CAT III 1000 V safety rating

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.

Safe attach on probe tips

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.
