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 Analyzer
1
to measure low-level RF power (≤200 mW) at the
ANT IN port.
1. Spectrum Analyzer is optional on some Test Set models.
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.
