Appendix A — Connector Care and Handling

Anritsu MA24106A Power Sensors are high-quality precision laboratory instruments and should receive the same care and respect afforded to such instruments. Follow the precautions listed below when handling or connecting these devices. Complying with these precautions will guarantee longer component life and less equipment down time due to connector or device failure. Also, such compliance will ensure that Power Sensor failures are not due to misuse or abuse – two failure modes not covered under the Anritsu warranty.

Beware of destructive pin depth mating connectors

Destructive pin depth of mating connectors is the major cause of failure in the field. When an RF component is mated with a connector having a destructive pin depth, damage will usually occur to the RF component connector. A destructive pin depth is one that is too long in respect to the reference plane of the connector (Figure A-1,left).

The center pin of a precision RF component connector has a precision tolerance. The mating connectors of various RF components may not be precision types. Consequently, the center pins of these devices may not have the proper pin depth. The pin depth of DUT connectors should be measured to assure compatibility before attempting to mate them with Power Sensor connectors. An Anritsu Pin Depth Gauge or equivalent can be used for this purpose (Figure A-1,right)

Figure A-1. Pin Depth

If the measured connector is out of tolerance in the “+” region, the center pin is too long (see Table A-1,below). Mating under this condition will likely damage the precision RF component connector. If the test device connector measures out of tolerance in the “–” region, the center pin is too short. This should not cause damage, but it will result in a poor connection and a consequent degradation in performance.

		–0.000	–0.030
N-Female	SC3825	0.207 +0.000	0.207 +0.000
