Input Signal Requirements
The TX Power measurement will complete and meet its accuracy specification of less than ±0.6dB when.
• Level is between −20dBm and +3 dBm.
• Level within ±3 dB of the expected input level.
• Frequency is within ±100kHz of expected input frequency.
Trigger Source
Auto triggering is the recommended trigger source for each measurement allowing the test set may choose the
preferred trigger source. However the user may want to select the trigger source. See Table 8. on page 107
