Setting Antenna Diagnostic Limits – Examples
Multi-Tech Systems, Inc. CDMA C1 AT Commands Reference Guide (PN S000478C)
For Hardware versions 2.1 and later:
This example shows how to calculate and specify antenna diagnostic low and high limit values for
hardware versions 2.1 and later. The AT+ADC command is used to read the value of the antenna
voltage divider so that the limits can be determined. Please note that this is an example only. Your
antenna characteristics may be different.
Set Primary Antenna Diagnostic Limits
This command enables or disables power to the secondary antenna. A secondary active GPS
antenna requires a power source. For these types of antennas, power to the GPS antenna should
be enabled with this command.
The AT+WANT command is also used when determining the non-powered limits of the diagnostic
check. See the AT+WANTLIM command for more information.
The state of AT+WANT is persistent across power-downs.
Command Syntax: AT+WANT=<value>
<value>
Note: Enable primary antenna internal ADC as the source of the
primary antenna diagnostic reading.
Command
AT+WANT=?
Note: Display valid parameter range
AT+WANT?
Note: Display current setting
AT+WANT
Default: Disable power to the secondary antenna
AT+WANT=1
Note: Enable power to the secondary antenna
Command
AT+WANTADC=0<cr>
Attach primary antenna.
AT+ADC=6<cr>
Request the primary antenna ADC voltage.
Assume a +/- 5% variance in antenna ADC reading.
Low limit = 130 – (.05 * 130) = 123
Open limit = 130 + (.05 * 130) = 137
AT+WANTLIM=1,1,123,137<cr>
Set primary antenna diagnostic limits.
AT+WANTS<cr>
Check antenna diagnostic status.

Power to the secondary antenna is disabled.
Power to the secondary antenna is enabled.
Diagnostic testing of the un-powered GPS antenna is enabled. (Note: non-persistent
setting for diagnostic setup only). This setting has no effect for hardware versions 2.1
and later. Un-powered diagnostics for the secondary antenna are not available for
hardware versions 2.1 and later.
