Possible Setup Issues

If the DTMF symbols are not captured correctly, the it is possible that the Trigger Arm setting of the measurement is Continuous and the gate time is small. It is recommended to set the trigger arm state to single and retry measurement.

If more than 16 DTMF symbols are transmitted, the DTMF measurement only provides results for the first 16 DTMF symbols detected.

If the input signal is not present or is less than the minimum required input signal, then the integrity is set to "Under Range" and all other results of the measurement are 9.91E+37.

If the input signal overdrives the receiver or is clipped by the receiver, then the integrity is set to "Over Range" and all other results of the measurement are 9.91E+37.
