NOTE: During a W-CDMA or W-CDMA (with HSDPA) Analyzer measurement, a yellow triangle symbol may temporarily appear beside "GPS" in the lower right. The yellow triangle indicates that the test set is re-synchronizing with the GPS pulses. Once the test set is synchronized, a green dot appears in place of the triangle. If the GPS is unavailable, a red X appears. If this happens, you must choose another reference.
