MIL-PRF-39012/2H
Leakage (pressurized connectors): Not applicable.
Insulation resistance: Method 302 of MIL-STD-202, test condition B. 5,000 megohms minimum.
Center contact retention: (Applicable to captivated-center-contact connectors only.) 15 pounds (66.72
N) minimum axial force for all cables except M17/128-RG400 and M17/60-RG142; 6 pounds (26.69 N)
minimum for M17/128-RG400 and M17/60-RG142.

Voltage standing wave ratio (VSWR): From 500 to 11 GHz, or approximately 80 percent of upper cutoff
frequency of the cable, whichever is lower; 1.30 maximum (1.45 max. to 11 GHz for X503, -X504,
-X513 and X514).
Swept frequency VSWR test setup:
Item 6: VSWR shall be less than 1.008 + .002 F (F in GHz).
Item 16: VSWR shall be less than 1.008 + .002 F (F in GHz).
Second step of VSWR checkout procedure: VSWR shall be less than 1.012 + .004 F (F in GHz).
Group B inspection: VSWR shall be less than 1.024 + .007 F (F in GHz).
Qualification and group C inspection: VSWR shall not exceed 1.08.
Connector durability: 500 cycles minimum at 12 cycles/minute maximum. The connector shall meet the
mating characteristics and force to engage and disengage requirements.
Contact resistance: In milliohms maximum.
