Page 79 Environmental Specifications Samples of this product have been type-tested in accordance with the Keysight Environmental Test Manual and verified to be robust against the environmental stresses of storage, transportation and end-use; those stresses include but are not limited to temperature, humidity, shock, vibration, and power-line conditions. Test methods are aligned with IEC 60068-2 and levels are similar to MIL-PRF-28800F Class 3.
Page 80 Mechanical characteristics, such as center conductor protrusion and pin depth, are not warranted performance specifications. They are, however, important supplemental characteristics related to the electrical performance of devices. Keysight Technologies verifies the mechanical characteristics of the devices with special gaging processes and electrical testing. These processes ensure that the device connectors do not exhibit any excess center conductor protrusion or improper pin depth when the module leaves the factory.
