Chapter 23, TX Test Screen Field Descriptions TX Freq Error, TX Frequency This measurement area is used to display transmitter frequency error or transmitter frequency. See Also “Tune Mode” on page 568 TX Power Transmitter power measures RF power at the RF IN/OUT port. Operating Considerations Maximum signal levels at each port are printed on the front panel. Only the RF IN/OUT port can be used for measuring TX Power on this screen. When the Input Port is set to Ant, four dashes (- - - -) appear in place of digits for this measurement. Use the Spectrum Analyzer1 to measure low-level RF power (≤200 mW) at the ANT IN port. CAUTION: Connecting a signal of >200 mW to the ANT IN port can cause instrument damage (although internal protection circuits can typically withstand a short-duration signal of 1 or 2 Watts). If the overpower circuit is triggered (signified by a warning message at the top of the screen), remove the signal from the ANT IN port, and press the MEAS RESET key or turn the Test Set off and on to reset it. See Also “Input Port” on page 567 (Operating Considerations) “TX Power” on page 569 “TX Power” on page 490 “TX Pwr Zero” on page 491 1. Spectrum Analyzer is an option on some Test Set models. 569 Main Menu
