
CA-158RS cable is used together with this jig for RF testing

VBAT functions can be performed in the CU-4. Calibration voltages and currents
e.g. are protected and monitored by the CU-4 interface software (protection
for over-current, overvoltage and reverse voltage).
VBAT can be powered through MJ-305 with external power. MJ-305 provides
the VBATT with SMPS regulation to 3.9V/2A and regulation bypass with
overvoltage protection (trip point ~4.4VDC). The VBATT external supply is
provided with overvoltage protection (trip point ~16.5VDC), polarity protection
and over-current protection (fuse 2.5A slow).
