14.3.1î™–î™–î™–î™–Description
Measures the DC component of load of the cellular antenna (the GPS antenna is RFU). The antenna load is
expressed in kOhm.

14.3.3î™–î™–î™–î™–Defined values
Parameter Type Description
<antenna_id> Number Antenna identifier (optional parameter)
• 0 (default value): cellular antenna
• 1: GPS antenna (RFU)
<antenna_load> Number Measured value in kOhm of the antenna load with a resolution of 1 kOhm. The range
goes from -1 to 53 (only integer values can be assumed), where:
• -1: open circuit
• 0: short circuit
• 1: 1 kOhm (minimum limit of the measurement range)
...
• 53: 53 kOhm (maximum limit of the measurement range)
14.3.4î™–î™–î™–î™–Notes
•
The
load
resistor
values
below
the
minimum
limit
of
1
kOhm
are
identified
as
short
circuit
(<antenna_
load>=0),
while
values
above
the
maximum
limit
of
53
kOhm
are
identified
as
open
circuit
(<antenna_
load>=-1).
• The reported value could differ from the real resistance value of the diagnostic resistor mounted inside
the antenna assembly due to antenna cable length, antenna cable capacity and the measurement
method.

14.4.1î™–î™–î™–î™–Description
Sets the UART power saving configuration, but it has a global effect on the module power saving configuration:
• If the power saving is enabled (+UPSV: 4), the UART interface is disabled after 6 s of inactivity and the
module enters the idle mode automatically whenever possible
